Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

Detection of transposition of the great arteries in fetuses reduces neonatal morbidity and mortality. (1/4202)

BACKGROUND: Transposition of the great arteries (TGA) is a life-threatening malformation in neonates, but it is amenable to complete repair. Prenatal detection, diagnosis, and early management may modify neonatal mortality and mortality. METHODS AND RESULTS: Preoperative and postoperative morbidity and mortality were compared in 68 neonates with prenatal diagnosis and in 250 neonates with a postnatal diagnosis of TGA over a period of 10 years. The delay between birth and admission was 2+/-2.8 hours in the prenatal group and 73+/-210 hours in the neonatal group (P<0.01). Clinical condition at arrival, including metabolic acidosis and multiorgan failure, was worse in the neonatal group (P<0.01). Once in the pediatric cardiology unit, the management was identical in the 2 groups (atrioseptostomy, PGE1 infusion, operation date). Preoperative mortality was 15 of 250 (6%; 95% CI, 3% to 9%) in the neonatal group and 0 of 68 in the prenatal group (P<0.05). Postoperative morbidity was not different (25 of 235 versus 6 of 68), but hospital stay was longer in the neonatal group (30+/-17 versus 24+/-11 days, P<0.01). In addition, postoperative mortality was significantly higher in the neonatal group (20 of 235 versus 0 of 68, P<0.01); however, the known risk factors for operative mortality were identical in the 2 groups. CONCLUSIONS: Prenatal diagnosis reduces mortality and morbidity in TGA. Prenatal detection of this cardiac defect must be increased to improve early neonatal management. In utero transfer of fetuses with prenatal diagnosis of TGA in an appropriate unit is mandatory.  (+info)

Preterm labor. (2/4202)

Preterm labor is the leading cause of perinatal morbidity and mortality in the United States. It is characterized by cervical effacement and/or dilatation and increased uterine irritability before 37 weeks of gestation. Women with a history of preterm labor are at greatest risk. Strategies for reducing the incidence of preterm labor and delivery have focused on educating both physicians and patients about the risks for preterm labor and methods of detecting preterm cervical dilatation. Methods used to predict preterm labor include weekly cervical assessment, transvaginal ultrasonography, detection of fetal fibronectin and home uterine activity monitoring. As yet, it is unclear if any of these strategies should be routinely employed. At present, management of preterm labor may include the use of tocolytic agents, corticosteroids and antibiotics.  (+info)

A new lethal syndrome of exomphalos, short limbs, and macrogonadism. (3/4202)

We report a new lethal multiple congenital abnormality (MCA) syndrome of exomphalos, short limbs, nuchal web, macrogonadism, and facial dysmorphism in seven fetuses (six males and one female) belonging to three unrelated families. X rays showed enlarged and irregular metaphyses with a heterogeneous pattern of mineralisation of the long bones. Pathological examination showed adrenal cytomegaly, hyperplasia of Leydig cells, ovarian stroma cells, and Langherans cells, and renal microcysts. We suggest that this condition is a new autosomal recessive MCA syndrome different from Beckwith-Wiedemann syndrome, especially as no infracytogenetic deletion or uniparental disomy of chromosome 11 was found.  (+info)

Pregnancy detection and the effects of age, body weight, and previous reproductive performance on pregnancy status and weaning rates of farmed fallow deer (Dama dama). (4/4202)

Fallow does (n = 502) of different ages (mature, 2-yr-old, and yearling) were maintained with bucks for a 60-d breeding season to determine whether previous reproductive performance and changes in BW affect doe pregnancy rates and to compare the effectiveness of ultrasonography and serum pregnancy-specific protein B (PSPB) for the detection of pregnancy in fallow does. Ultrasonography was performed, blood samples collected, and BW recorded at buck removal (d 0) and at 30 and 90 d after buck removal. Lactational status (lactating = WET; nonlactating = DRY) were determined from farm records taken at weaning prior to each breeding season (autumn 1990 through autumn 1994). Ultrasonography and PSPB for determining pregnancy were in agreement 93% of the time. Overall pregnancy rates did not differ (P>.10) relative to age of the doe; the combined pregnancy rate was 92%. We also determined that 82.9% of does conceived early in the breeding season and that the incidence of embryonal-fetal mortality during the first 90 d after buck removal was 2.8%. In general, mature and 2-yr-old DRY does were heavier and had lower pregnancy rates than WET does. The overall weaning rate for all does was 77.9%. Loss in the number of fawns from pregnancy detection to weaning was equivalent to 14.8% for mature does, 24.7% for 2 yr old does, and 42.5% for yearling does. These data indicate that even though pregnancy rates were relatively high, further study is needed to determine the causes associated with subsequent fawn losses, particularly among yearling does. As a production tool, lactational WET/ DRY status testing was found to be an acceptable means for determining the reproductive potential of individual does within the herd. In addition, serum PSPB may be used in place of ultrasonography for pregnancy diagnosis in fallow deer as early as d 30 after buck removal.  (+info)

Ventriculo-atrial time interval measured on M mode echocardiography: a determining element in diagnosis, treatment, and prognosis of fetal supraventricular tachycardia. (5/4202)

OBJECTIVE: To determine whether M mode echocardiography can differentiate fetal supraventricular tachycardia according to the ventriculo-atrial (VA) time interval, and if the resulting division into short and long VA intervals holds any relation with clinical presentation, management, and fetal outcome. DESIGN: Retrospective case series. SUBJECTS: 23 fetuses with supraventricular tachycardia. MAIN OUTCOME MEASURES: A systematic review of the M mode echocardiograms (for VA and atrioventricular (AV) interval measurements), clinical profile, and final outcome. RESULTS: 19 fetuses (82.6%) had supraventricular tachycardia of the short VA type (mean (SD) VA/AV ratio 0.34 (0.16); heart rate 231 (29) beats/min). Tachycardia was sustained in six and intermittent in 13. Hydrops was present in three (15.7%). Digoxin, the first drug given in 14, failed to control tachycardia in five. Three of these then received sotalol and converted to sinus rhythm. All fetuses of this group survived. Postnatally, supraventricular tachycardia recurred in three, two having Wolff-Parkinson-White syndrome. Four fetuses (17.4%) had long VA tachycardia (VA/AV ratio 3.89 (0.82); heart rate 226 (10) beats/min). Initial treatment with digoxin was ineffective in all, but sotalol was effective in two. Heart failure caused fetal death in one and premature delivery in one. All three surviving fetuses had recurrences of supraventricular tachycardia after birth: two had the permanent form of junctional reciprocating tachycardia and one had atrial ectopic tachycardia. CONCLUSIONS: Careful measurement of ventriculo-atrial intervals on fetal M mode echocardiography can be used to distinguish short from long VA supraventricular tachycardia and may be helpful in optimising management. Digoxin, when indicated, may remain the drug of choice in the short VA type but appears ineffective in the long VA type.  (+info)

Individual growth patterns in the first trimester: evidence for difference in embryonic and fetal growth rates. (6/4202)

OBJECTIVE: To evaluate individual fetal growth during the first trimester in pregnancies resulting from spontaneous and in vitro fertilization (IVF). METHODS: The growth of 11 fetuses conceived by spontaneous fertilization (known dates of ovulation) in nine patients and 15 fetuses conceived by IVF in 12 patients were evaluated at weekly intervals from 6 weeks, menstrual age, to 14 weeks. Fetal length was determined at each examination. Measures of fetal length included the crown-rump length (CRL), maximum straight line length (MSLL) and maximum axial length (MAL). Comparisons of CRL and MSLL to MAL were carried out. The MSLL was used as the measure of length except when the MAL was available. Linear and quadratic functions were fitted to the complete data sets of individual fetuses in the two groups. Individual data sets from ten fetuses in each group were then divided into early and late growth phases, and linear functions were fitted to each data subset. Start points and pivotal points for each fetus were estimated from the coefficients of these two functions. Growth in these two groups of fetuses was compared, on the basis of slope values. RESULTS: Evaluation of length measures indicated that, before 8 weeks, only MSLL could be measured. After 8 weeks, all three measures could be obtained, with the MAL being the largest. Both the linear and quadratic models performed well with individual data sets (mean R2(+/- SD): linear 98.1 (1.0)%; quadratic 99.4 (0.4)%), with no differences found between spontaneous and IVF groups (maximum possible differences in mean slopes (95% probability): 5-8%). Similar findings were obtained for the early and late growth phase data subsets. Slope values in the early and late growth phases showed low variability (CV: early 13.5%; late 11.6%), but were significantly different (early 0.72 (+/- 0.10 SD) cm/week; late 1.21 (+/- 0.14 SD) cm/week). The mean start point was 5.9 (+/- 0.3 SD) weeks' menstrual age, while the mean pivotal point was 9.2 (+/- 0.7 SD) weeks, menstrual age. CONCLUSIONS: First-trimester growth studies in individual fetuses indicate that there is a change in length growth rate between 9 and 10 weeks, menstrual age. This is consistent with a shift in development from organogenesis to growth. These results can be used for more accurate assessment of first-trimester growth and may aid in the detection of fetal problems that manifest themselves as growth abnormalities.  (+info)

Accuracy of sonographic estimates of fetal weight in very small infants. (7/4202)

OBJECTIVE: Fetal outcome is inversely related to gestational age and birth weight. Therefore, in very small fetuses, estimated weight may play an important role in clinical management. Our aim was to determine the accuracy of sonographic estimates of fetal weight in very small infants. DESIGN: Retrospective chart review. SUBJECTS: We retrospectively studied 100 consecutive infants with a birth weight of < 1000 g, at a gestational age between 24.0 and 34.0 weeks, in which biometric data < 2 weeks prior to delivery were available for analysis. METHODS: We estimated fetal weight with the use of two methods--by those of Hadlock and colleagues and Scott and colleagues--and compared the estimated values with measured birth weights. RESULTS: The infants had a mean birth weight of 742 +/- 173 (SD) g, at a gestational age of 28.1 +/- 2.0 (SD) weeks. With Hadlock's method, the mean estimated fetal weight (EFW) was 736 +/- 186 (SD) g, which was not significantly different from birth weight; the mean EFW error was 0.8 +/- 12.7 (SD) %. With Scott's method, the mean EFW was 780 +/- 185 (SD) g, which was significantly increased above birth weight; the mean EFW error was 5.7 +/- 12.5 (SD) %. The accuracy of the weight estimates was not significantly affected by the period between ultrasound examination and delivery if < 2 weeks, or by fetal growth restriction. CONCLUSION: In our population of small fetuses, Hadlock's estimates of fetal weight correlated well with measured birth weight, whereas Scott's method tended to overestimate.  (+info)

Clinical interpretation of ultrasound biometry for dating and for assessment of fetal growth using a wheel and chart: is it sufficiently accurate? (8/4202)

OBJECTIVES: To investigate how accurately practicing obstetricians (experts) can apply dating rules and compare the interpretation of gestation-sensitive ultrasound data with those of a computer system. SUBJECTS: Seventeen practicing obstetricians. Members of the Royal College of Obstetricians and Gynaecologists, from 14 different units throughout the UK. DESIGN: Six cases with menstrual and ultrasound data together with identical ultrasound charts and obstetric wheels. MAIN OUTCOME MEASURES: Concordance between the calculated estimated date of delivery (EDD) and growth assessment provided by the experts and the computer system. RESULTS: The calculation of the EDD by the experts was imprecise (59% within 3 days overall). Concordance with the computer calculation was poorest when the ultrasound measurements lay close to the upper or lower centile lines (average 7% within 3 days of the computer). Interpretation of growth showed good concordance with the computer when gestation was not critical to the interpretation (94%), but very poor when gestation was critical (7%). CONCLUSIONS: Calculation of EDD by means of an obstetric wheel and charts is not precise. Compared with the computer system, these errors have a significant effect on the subsequent interpretation of growth scans when the data are borderline. A computer system provides the more accurate method for interpreting gestation-sensitive ultrasound biometry.  (+info)

Obstetric ultrasonography is the use of medical ultrasonography in pregnancy, in which sound waves are used to create real-time visual images of the developing embryo or fetus in its mothers uterus (womb). The procedure is a standard part of prenatal care in many countries, as it can provide a variety of information about the health of the mother, the timing and progress of the pregnancy, and the health and development of the embryo or fetus. The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) recommends that pregnant women have routine obstetric ultrasounds between 18 weeks and 22 weeks gestational age (the anatomy scan) in order to confirm pregnancy timing, to measure the fetus so that growth abnormalities can be recognized quickly later in pregnancy, and to assess for congenital malformations and multiple pregnancies (i.e. twins). Additionally, the ISUOG recommends that pregnant women have obstetric ultrasounds between 11 weeks and 13 weeks 6 days gestational age in ...
Fetal echocardiography is the name of the test used to diagnose cardiac conditions in the fetal stage. Cardiac defects are amongst the most common birth defects. Their diagnosis is important in the fetal stage as it might help provide an opportunity to plan and manage the baby as and when the baby is born. Not all pregnancies need to undergo fetal echo. Specific maternal and fetal conditions would indicate the need for this test. these conditions are as listed below: Maternal: Diabetes Anticonvulsant intake Prev child with CHD Infections: Parvovirus, Rubella, Coxsackie AutoImmune Disease: Anti Rho/La positive Fetal: Increased Nuchal thickness Abnormal ductus venosus Abnormal fetal cardiac screening Major extracardiac abnormality Abnormal Fetal karyotype Hydrops Fetal dysrthythhmia Fetal Echo is usually performed by a Pediatric Cardiologist but may also be performed by a Sonologist. To date, no detrimental effects in humans have been demonstrated. The performance of a fetal echocardiogram ...

This is a traditional (narrative) review with the objective of highlighting the contribution of obstetric ultrasonography (US) between the 11th and 14th week of pregnancy, commonly called first trimester anomaly scan. In addition to being used for the screening of chromosomal anomalies, US can be employed during this period to confirm or determine gestational age, evaluate fetal anatomy, diagnose malformations, screen major structural abnormalities and genetic syndromes, define the prognosis of pregnancy, diagnose and characterize multiple pregnancies, and screen preeclampsia and intrauterine growth restriction. The most important studies about this subject published between 1990 and 2010 in the Cochrane and PubMed libraries were included. The selected studies can be classified with scientific levels I to III ...

Fetal ultrasound is a test done during pregnancy that uses reflected sound waves to produce a picture of a fetus, the organ that nourishes the fetus (placenta), and the liquid that surrounds the fetus (amniotic fluid). The picture is displayed on a TV screen and may be in black and white or in color. The pictures are also called a sonogram, echogram, or scan, and they may be saved as part of your babys record.. Fetal ultrasound is the safest way to check for problems and get information about your fetus, such as its size and position. It does not use X-rays or other types of radiation that may harm your fetus. It can be done as early as the 5th week of pregnancy. The sex of your fetus can sometimes be determined by about the 18th week of pregnancy. ...

What an informative article! You answered so many of my questions I have been wondering about for months now. This is my 4th pregnancy and right from the start of feeling movements I knew there was something different than the others. All my other babies had been anterior. But with this one, who also has the placenta on the posterior side, I could feel so much more movements all over the front the last few months. I am 37 weeks now and baby is mostly posterior. It has turned sideways a few times too. It still moves alot though, so I am not too worried. I am also showing smaller and my babies have been in the 8lb 6oz to 10lb 4oz range. So I was starting to wonder if this baby is in fact smaller, when my gut tells me the baby is big like the others. I am planning another homebirth, so it would be nice if this baby turned anterior for labour. ...

Objectives:To establish the reference ranges for fetal biparietal diameter and head circumference obtained by transabdominal ultrasound examination in the first trimester in Chinese women.Methods:In this prospective cross-sectional study, 1351 normal singleton fetuses were examined transabdominally by 2 experienced observers in the first trimester of pregnancy in which the CRL was between 55 and 84 mm. Measurements of Biparietal Diameter (BPD), head circumference (HC) were prospectively collected. Charts and predictive equations were constructed from data obtained.Results:Measurements of BPD, HC were correlated with CRL. CRL-based predictive equations were calculated using polynomial least squares regression analysis. HC = 7.710583 + 1.387393 * CRL-0.0037807 * CRL², R² = 0.5735, P = 0.000. BPD = 6.855277 + 0.2389065 * CRL, R² = 0.5355, P = 0.000. CRL-specific biometric charts were constructed.Conclusions:There was a general increase in fetal biparietal diameter and head circumference with CRL.

OBJECTIVES: This study was aimed at establishing an ideal method for performing three-dimensional measurements of the fetus in order to improve the estimation of fetal weight. METHODS: The study consisted of two phases. Phase I was a prospective cross-sectional study performed between 28 and 40 weeks gestation. The study population (n=110) comprised low-risk singleton pregnancies who underwent a routine third-trimester sonographic estimation of fetal weight. The purpose of this phase was to establish normal values for the fetal abdominal and head volumes throughout the third trimester. Phase II was a prospective study that included patients admitted for an elective cesarean section or for induction of labor between 38 and 41 weeks gestation (n=91). This phase of the study compared the actual birth weight to two- (2D) and three-dimensional (3D) measurements of the fetus. Conventional 2D ultrasound fetal biometry was performed measuring the biparietal diameter (BPD), head circumference (HC), abdominal
Background Second trimester routine ultrasound evaluation of the fetal heart by means of the four-chamber view has been proposed for prenatal detection of cardiac anomalies. The aim of this study was to evaluate the efficacy of this procedure.. Methods and Results A prospective follow-up study on 6922 scanned fetuses was performed. Pregnant women without known risk factors who were scheduled for a routine fetal ultrasound examination between 16 and 24 weeks gestation were invited to participate. Follow-up until 6 months postpartum was available for 5660 subjects (81.8%), of whom 5319 fulfilled all eligibility criteria. By comparing the prenatal diagnosis to the postnatal diagnosis, we obtained sensitivity, specificity, and predictive value (positive and negative). A total of 80 cases of congenital malformations were diagnosed during the study: 44 cases of congenital heart disease, 40 cases of noncardiac malformations, and a combination of the two in 4 cases. The fetal four chamber-view ...

N2 - Since the fetal heart is small and less visible, physicians find it based on the fetal position and orientation assumed with acquired US images. Meanwhile, an artifact due to bones and fetal movement in uterus not only makes the procedure cumbersome but also limits the reliability of diagnosis. Then, this paper proposes the robotic US imaging system allows for the estimation of fetal position and orientation based on the fetal bone distribution which is a key anatomical feature to detect the heart and to avoid the artifact. We obtain intrauterine bone distribution in three dimensions from echo images and estimate the ...
This was a prospective observational study of an unselected obstetric population in whom routine anomaly scans are performed at 18-23 weeks gestation. Between January 1997 and August 1999 all women booked for antenatal care at our institution and subsequently delivered within our unit were included in the study. High risk referrals from other hospitals were excluded to eliminate bias.. Two full time and four part time sonographers working only in obstetric ultrasound performed routine ultrasound scans. The obstetric ultrasound service was situated within a unit that provided fetal medicine and echocardiography services. High resolution ultrasound equipment with a cineloop facility (ATL 3000/5000, Letchworth, UK and Acuson XP10, Uxbridge, UK) was used.

Fetal double aortic arch (DAA) malformation is a rare congenital heart disease with few reported cases in the literature. We aimed to investigate the characteristics of prenatal ultrasound and postnatal computed tomography angiography (CTA) of DAA and to describe the associated anomalies and clinical outcomes to improve prenatal diagnosis and assist in perinatal management. The obstetric ultrasound imaging databases of seven tertiary referral centers were reviewed retrospectively to identify fetuses with a prenatal diagnosis of DAA between January 2013 and December 2018. Ultrasonographic findings, associated anomalies, genetic abnormalities, postnatal CTA images, and long-term postnatal outcomes were evaluated. A total of 36 cases out of 40 prenatally diagnosed DAA fetuses were confirmed by postnatal diagnosis (fetal autopsy, CTA, and surgery). In this cohort of 36 confirmed cases, 24 (67%) were isolated anomalies, while 12 (33%) were associated with intracardiac or extracardiac anomalies, and 2 (6%)
TY - JOUR. T1 - Prenatal detection of neuroblastoma by fetal ultrasonography. AU - Saylors, Robert L.. AU - Cohn, Susan L.. AU - Morgan, Elaine R. AU - Brodeur, Garrett M.. PY - 1994/1/1. Y1 - 1994/1/1. N2 - Purpose We report three cases of neuroblastoma diagnosed by prenatal ultrasound examination and examine the biologic features of tumors diagnosed prenatally.: Patients and Methods Neuroblastoma is the most common tumor detected in the newborn period. Thus, some of these tumors develop prenatally and should be detectable by maternal ultrasound. Here we report three cases in which a neuroblastoma was suspected on prenatal ultrasonography. In addition, we review selected features of 17 additional cases reported in the literature.: Results and Conclusions These data indicate that, although the majority of patients have favorable clinical and biological features and do well, some patients do not, and the DNA index may be the most important predictor of outcome.. AB - Purpose We report three cases ...

2006 all cases of fetal SUA, from Security Forces Hospital, Riyadh, Kingdom of Saudi Arabia, in a routine obstetric population were studied. Targeted sonograms and perinatal follow up were obtained. Sixteen thousand women completed the study, 162 cases of SUA were diagnosed on the basis of prenatal sonograms, however 169 cases [53 non isolated SUA and 116 isolated SUA] confirmed postnatafly. The sensitivity, specificity, positive predictive value and negative predictive value of prenatal ultrasonographic diagnosis of SUA were 90.5%, 99.9%, 94.4% and 99.8% respectively. Aneuploidy and cardiac abnormalities were present in 8 out of the 53 [15%] and 17/53 [32%] In none isolated SUA respectively. fetuses with SUA should get further evaluation at centers that handle high-risk cases and parent should strongly counseled for fetal echocardiogram and fetal karyotyping In case of none isolated SUA ...
Conventionally volume measurements can be made by using multiplanar or VOCALTM (Virtual Organ Computer-aided AnaLysis). Recently, a new technique, XI VOCALTM (eXtended Imaging VOCAL) has been described. Combined with the inversion mode, measurements for the liquid-filled structures can also be made. The potential use in clinical diagnosis and prediction of pathologies of volume measurements particularly in the first trimester are yet to be investigated.. 3D ultrasound is found to be superior to 2D parameter in volumetry measurement. However, currently, there are still very few studies done to evaluate the potential use of volumetry measurement in clinical practice, especially of the validity and reproducibility of XI VOCALTM; and the variation of results obtained within different ultrasound machines. Due to the potential use of volumetry measurements in clinical practice, the accuracy in volumetry measurement is very important and the development of new technique need to be fully explored so ...
Topical articles are focused on the maternal state but lack detailed fetal description. It is worth to discussing whether COVID-19 maternal infection should be indication for further, more specific fetal ultrasound. Scientists and experts agree that fetal monitoring should be conducted using ultrasonography [12, 14]. Ultrasound assessment of fetal growth, amniotic fluid volume, umbilical artery Doppler, and fetal heart rate should be checked [12, 14]. More advanced monitoring is recommended once the fetus reaches viability [14]. Other viral fetal infections co-occur with prenatal symptoms, which can be detected by ultrasonography (Table 2) [15-18]. Ye et al. presented a study suggesting that maternal viral infection is significantly associated with risk of congenital heart defect in offspring [19]. Viruses such as cytomegalovirus (CMV) and rubella virus can cause transplacental infection. Other viruses are occasionally able to gain access to the fetus via the hematogenous route. Herpes simplex ...

The pandemic of COVID-19 is seriously challenging the medical organization in many parts of the world. This novel corona virus SARS-CoV-2 has a specific tropism for the low respiratory airways, but causes severe pneumonia in a low percentage of patients. However, the rapid spread of the infection during this pandemic is causing the need to hospitalize a high number of patients. Pneumonia in COVID-19 has peculiar features and can be studied by lung ultrasound in the early approach to suspected patients. The sonographic signs are non-specific when considered alone, but observation of some aspects of vertical artifacts can enhance the diagnostic power of the ultrasound examination. Also, the combination of sonographic signs in patterns and their correlation with blood exams in different phenotypes of the disease may allow for a reliable characterization and be of help in triaging and admitting patients.
I. Introduction The ultrasound community involved with obstetric sonography has been grappling with a controversial issue for a number of years. The issue centers on the so-called soft markers for Down syndrome (trisomy 21) and other trisomic chromosomal anomalies. Recently, the issue has been hotly debated at major meetings of medical organizations involved in sonographic diagnosis, including the American Institute of Ultrasound in Medicine (AIUM) and the Society of Radiologists in Ultrasound. Importantly, both sides of the argument were well intentioned. What emerged from these debates was the realization that experts on opposite sides of the argument were actually closer to agreement than they had previously thought when it came to the identification of some of these soft markers in lowrisk women. Many of these soft markers have been described. However, 2 of these markers have been the source of the greatest controversy. These are the choroid plexus cyst (CPC) and the echogenic ...
Ultrasound scans, also known as sonograms, use the reflection of high-frequency sound waves to create images. The standard 2D obstetric ultrasound shows a flat, black and white picture on a screen.. 2D ultrasounds can be done during any trimester, but are often performed early in gestation to confirm the pregnancy and to help establish the due date. This scan is usually repeated at 18-20 weeks of gestation to check for normal growth and development, and to reveal the sex of the baby if desired.. While trained medical professionals have become adept at recognizing features of the developing fetus in 2D, parents are better able to visualize the baby with the advent of 3D ultrasonography.. A 3D ultrasound creates a different perspective by merging a series of 2D images taken from various angles into a composite to form a 3D picture. Because of this increased resolution and visibility, 3D ultrasounds capture a more detailed and realistic representation of the developing baby.. Because 3D ultrasounds ...

Apart from the technical details of diagnostic imaging; sonographers usually take care of administrative duties along with collecting patient information and maintaining files, such as patient histories and sonography results. The responsibility of maintaining sonography equipment inventory can be assigned to them. Some sonographers may be engaged in supervising the work of other staff members involved in diagnostic imaging work; these sonogram technicians could be required to perform other administrative duties including the scheduling of writing work.. Aspiring sonography technicians can choose a career specialization from several available choices such as vascular sonography, neuro-sonography, and gynecological and obstetric sonography.. Educational Prerequisites. Sonographers usually sharpen their skills in diagnostic imaging by undergoing hands on training or via formal education. Employers prefer sonographers who have completed healthcare programs or postsecondary programs that carry ...

If you cant remember your last menstrual period date or if you have consistently irregular cycles, the doctor can use can early ultrasound to give you a your your due date. While can may be more familiar with a trans-abdominal ultrasound, it is common for doctors to use a transvaginal ultrasound for pregnancy dating, especially early in the first trimester. If your first ultrasound gives you a due date that is more than 1. You may have simply conceived earlier or later than you thought you can which can happen if your cycle is at all why dating if you remembered your last menstrual period date incorrectly.. Your doctor might want to repeat the how to make sure that your pregnancy is developing as it should. Assuming that the subsequent ultrasound shows the expected fetal growth for the your period between the can, your doctor may revise your due date how match the first ultrasounds predictions. And as long as the repeat ultrasound shows consistent growth and there your no signs of problems, ...
INTRODUCTION: In a population-based study, we found an overall false-positive rate of 8.8% for the second and third trimester ultrasounds. Although numerous studies have been performed to examine factors which lead to false negatives, the same is not true for the factors associated with false positives. The principal objective of this study was to look for risk factors for false-positive diagnoses of fetal malformations on obstetric ultrasound scans. MATERIAL AND METHODS: In this nested case-control study, the case infants were those whose mother had a false-positive antenatal ultrasound diagnosis of a malformation during the second or third trimester (ultrasound false-positives) and who were live- or stillborn in Auvergne in 2006-2010 ...

Dynamic application and manipulation of the basic controls will provide for enhanced image optimization and increased abnormality conspicuity.. Adjustment of power is generally limited to the start of the exam, if manipulated at all. This should be set to a relative standard for each ultrasound machine. Keeping power the same across the diverse patient caseload contributes to the identification of abnormal tissue pathology.. Gain should be manipulated for each patient, and often throughout the individual exam. The more variable penetration in depth required during a patient examination, the more manipulation of the gain control may be needed. Gain controls the amplification of echoes returning to the probe, which is used in image formation. Gain controls the overall level of brightness of the image. Specifically 2D gain establishes the gray scale brightness across the entire image.. The Time-Gain-Compensation controls, usually a series of slides, allow for manipulation of gain segmentally by ...

The first trimester of pregnancy is the most critical moment for the embryo and fetal development in terms of rapid changes and modification of its internal and external appearance. The modern ultrasound equipment enables us to identify some of these changes as early as 5-7 weeks after the last menstrual period (LMP). The relevance of 3D ultrasound (3D US) in the detection and demonstration of fetal abnormalities has already been proven. Some of the 3D/4D tools have shown some benefits compared to the 2D US when a malformation is present. The 3D images are usually clearer for parents to understand the problem or the normality of the small fetus. There are five main aspects of the 3D/4D US to mention, which are relevant during the first trimester of pregnancy: (1) the multiplanar approach of the embryo and the fetus; (2) the ability to obtain planes that are not accessible with 2D US; (3) the possibility to do an off-line analysis of acquired 3D/4D volumes and telemedicine; (4) the images are ...

Twins fetal development at 3 weeks. The placenta also forms during this month. The progesterone helps prepare the endometrium (lining of the uterus). 8th month pregnancy foetal position and development A major development that occurs during the 8th month of pregnancy is the change in foetal position. The word trimester means â 3 months.â This can be confusing, because a normal pregnancy is 40 weeks, a bit longer than 9 months. At the end of month 6, your baby is about 12 inches long and can weigh close to 2 lbs! This is the month that his or her nervous system develops. At about 6 weeks, your babys heart beat can usually be detected. At this stage, you may begin to feel your baby moving around. As the fertilized egg grows, a water-tight sac forms around it, gradually filling with fluid. Throughout the third trimester, your baby will gain weight quickly, adding body fat that will help after birth. This is called the amniotic sac, and it helps cushion the growing embryo. If the fertilized egg ...
Introduction: Among congenital dysplasias the anomalies of kidney and urogenital tract are among the most frequent encountered. Their rate in prenatally made diagnoses is about 50 %. Modern prenatal diagnostic facilities have changed the therapeutic access to these anomalies in the last decade. After a phase of overtreatment in the beginning, nowadays new insights in the natural course of these dysplasias and the results of long-term follow-up studies resulted in a more differentiated apporach. Questions and methods: In this retro- and prospective study we looked for the the influence of prenatal diagnostics on the postnatal course and management. The question was to examine the relationship between the prenatal ultrasound results, the suggested prenatal diagnosis and then the defintive postnatal disease. Of interest was the prognostic impact of typical prenatal sonographic imaging on the postnatal course of the baby. Because of its frequency we focused on anomalies of the kidney and urogenital ...
Since the 1970s, pregnant women have been repeatedly told that ultrasound is just sound waves and, therefore, perfectly safe during pregnancy.. They have been encouraged by care providers to undergo multiple ultrasound scans and Doppler fetal heart monitoring (also ultrasound based) during pregnancy, and sometimes they and their babies are exposed to ultrasonic monitors for hours during hospital birth.. But ultrasound is not just sound waves. In fact, it is nonionizing radiation, and many hundreds of studies have shown that this type of radiation is harmful. Humans and other life forms are in danger from exposure to non-ionizing technologies, and this is especially true for children and developing babies in the womb.. We can find ultrasound listed on the FDAs website in a section entitled Radiation-Emitting Products. There we are told that ultrasound… is based on nonionizing radiation, so it does not have the same risks as X-rays… However, study after study has confirmed that ...

Objectives To examine associations between ultrasonography (US) assessments (B-mode (BM) and power Doppler (PD)) of a large number of joints and traditional assessments of disease activity, and to examine the sensitivity to change of the US scores and clinical measures in patients with rheumatoid arthritis (RA).. Methods Twenty patients with RA initiating adalimumab treatment were examined at baseline and after 1, 3, 6 and 12 months with US (BM and PD) using an Outcome Measures in Rheumatoid Arthritis Clinical Trial semiquantitative scoring (0-3) of 78 joints as well as assessment of clinical and laboratory variables with calculation of composite indexes.. Results The US scores were associated with composite scores as well as clinical and laboratory variables (r=0.41-0.84, p,0.05-0.001 at 12-months follow-up). Compared with clinical assessments, US detected higher numbers of inflamed joints. The US scores decreased after 1 and 3 months (p,0.005) and PD showed the highest percentage improvement. ...

... surgical techniques are used to remove an invasive malignancy that extends to the clitoris. Standard surgical procedures are followed in these cases. This includes evaluation and biopsy. Other factors that will affect the technique selected are age, other existing medical conditions, and obesity. Other considerations are the probability of extended hospital care and the development of infection at the surgical site.[3] The surgery proceeds with the use of general anesthesia, and prior to the vulvectomy/clitoridectomy an inguinal lymphyadenectomy is first done. The extent of the surgical site extends one to two centimeters beyond the boundaries of malignancy. Superficial lymph nodes may also need to be removed. If the malignancy is present in muscular tissue in the region, it is also removed. In some cases, the surgeon is able to preserve the clitoris though the malignancy may be extensive. The cancerous tissue is removed and the incision is closed.[3] Post operative care may ...

In treating müllerian agenesis, the Vecchietti procedure is a laparoscopic surgical technique that produces a vagina of dimensions (depth and width) comparable to those of a normal vagina (ca. 8.0 cm. deep).[28][29] A small, plastic sphere ("olive") is threaded (sutured) against the vaginal area; the threads are drawn though the vaginal skin, up through the abdomen, and through the navel. There, the threads are attached to a traction device, and then daily are drawn tight so that the "olive" is pulled inwards and stretches the vagina, by approximately 1.0 cm. per day, thereby creating a vagina, approximately 7.0 cm. deep by 7.0 cm. wide, in 7 days. The mean operating room (OR) time for the Vecchietti vaginoplasty is approximately 45 minutes; yet, depending upon the patient and her indications, the procedure might require more time.[30] The outcomes of Vecchietti technique via the laparoscopic approach are found to be comparable to the procedure using laparotomy.[31] In vaginal hypoplasia, ...
