PURPOSE: Prostate needle biopsy is a commonly performed procedure since it is the most definitive form of cancer diagnosis. Magnetic resonance imaging (MRI) allows target-specific biopsies to be performed. However, needle placements are often inaccurate due to intra-operative prostate motion and the lack of motion compensation techniques. This paper detects and determines the extent of tissue displacement during an MRI-guided biopsy so that the needle insertion plan can be adjusted accordingly. METHODS: A multi-slice-to-volume registration algorithm was developed to align the pre-operative planning image volume with three intra-operative orthogonal image slices of the prostate acquired immediately before needle insertion. The algorithm consists of an initial rigid transformation followed by a deformable step. RESULTS: A total of 14 image sets from 10 patients were studied. Based on prostate contour alignment, the registrations were accurate to within 2 mm. CONCLUSION: This algorithm can be used ...

Background Multiparametric magnetic resonance imaging (MRI), with or without MRI‐targeted biopsy, is an alternative test to systematic transrectal ultrasonography‐guided biopsy in men suspected of having prostate cancer. At present, evidence on which test to use is insufficient to inform detailed evidence‐based decision‐making.. Objectives To determine the diagnostic accuracy of the index tests MRI only, MRI‐targeted biopsy, the MRI pathway (MRI with or without MRI‐targeted biopsy) and systematic biopsy as compared to template‐guided biopsy as the reference standard in detecting clinically significant prostate cancer as the target condition, defined as International Society of Urological Pathology (ISUP) grade 2 or higher. Secondary target conditions were the detection of grade 1 and grade 3 or higher‐grade prostate cancer, and a potential change in the number of biopsy procedures.. Search methods We performed a comprehensive systematic literature search up to 31 July 2018. We ...

bloomberg.com Researchers are finding evidence that patients who test positive for the coronavirus after recovering aren’t capable of transmitting the infection, and could have the antibodies that prevent them from falling sick again. Scientists from the Korean Centers for Disease Control and Prevention studied 285 Covid-19 survivors who had tested positive for the coronavirus after their illness had apparently resolved, as indicated by a previous negative test result. The so-called re-positive patients weren’t found to have spread any lingering infection, and virus samples collected from them couldn’t be grown in culture, indicating the patients were shedding non-infectious or dead virus particles. The findings, reported late Monday, are a positive sign for regions looking to open up as more patients recover from the pandemic that has sickened at least 4.8 million people. The emerging evidence from South Korea suggests those who have recovered from Covid-19 present no risk of

This video demonstrates the MRI/TRUS fusion biopsy procedure of a 62 year old male with history of elevated serum PSAs in the setting of multiple negative TRUS biopsies. The patient was initially biopsied under the standard of care 12-core TRUS with no evidence of prostate cancer with subsequent TRUS biopsies also demonstrating no evidence of cancer. The patient then elected to undergo MRI/US fusion biopsy. A diagnostic pre-biopsy multiparametric MRI with surface and endorectal coils was taken and identified one lesion that was highly suspicious for prostate cancer based on NIH scoring criteria. The entire fusion biopsy procedure using the UroNav platform is depicted and includes: patient preparation, TRUS sweep, MRI/TRUS image co-registration, and targeted and standard biopsy. Screenshots of the UroNav platform during biopsy target acquisition and sampling are shown followed by an optional 12-core TRUS biopsy ...
Biopsy-the removal of cells or tissue for microscopic examination-has a long history in medicine. The first percutaneous needle biopsy of the liver was reported in 1923, and the technique developed into an invaluable diagnostic tool in many organ systems.. The development of computed tomography (CT), ultrasound and magnetic resonance imaging (MRI), allowed physicians to use advanced imaging guidance with biopsies. Imaging-guided percutaneous needle biopsies achieve greater precision in targeting lesions, resulting in high sensitivities and low complication rates.. For the study, researchers looked for biopsy trends in Medicare claims data from 1997 through 2008 for 10 anatomical regions. Biopsy procedures increased from 1,380 per 100,000 Medicare enrollees in 1997 to 1,945 biopsies in 2008, representing a compound annual growth rate of 3 percent. In 2008, 67 percent of all biopsies were performed percutaneously, compared to 59 percent in 1997.. We also found that the use of imaging guidance ...

Postmortem computed tomography (pmCT) and pmCT angiography (pmCTA) provide a minimally invasive method to determine the cause of death. Postmortem image-guided biopsy allows for precise sampling of histological specimens. This case study describes the findings of lethal systemic fat embolism (FE) on whole-body unenhanced pmCT, pmCTA, and image-guided biopsy, with autopsy and histopathologic correlation. Unenhanced pmCT revealed a distinct fat level on top of sedimented layers of corpuscular blood particles and serum in the arterial system and pulmonary trunk. Subsequent pmCTA showed reproducible results, and image-guided biopsy confirmed fatal FE. pm CT/pmCTA combined with image-guided biopsy established the cause of death as right heart failure as a result of systemic fatal FE prior to autopsy. All imaging findings were consistent with traditional autopsy and histological specimens. This unique case demonstrates new imaging findings in massive, fatal FE and highlights that postmortem imaging, ...

You can read part 1 here.. Put the carrier in a sunbeam or other comfortable place.. If the cat is suspicious, and doesnt enter the carrier right away, toss in the treats, and walk away! Dont try to encourage or coax the cat into the carrier - - they will become suspicious, especially if they have had previous negative experiences with the carrier in the past. Do this every day to start with, and dont forget to walk away. Cats will soon eat the treats, first it may be when you arent watching. And most of them will start to spend time in the carrier.. Sense of Control: To protect themselves, cats want to have a sense of control over their environment. Cats are more secure if they have options to hide and the ability to monitor their environment from a higher place.. If instead of putting them on exam tables at the practice, we allow them to choose whether to be on the floor, in the carrier, or in another place, we will be much more successful in our goals for feline healthcare and reduction ...
Multiparametric magnetic resonance imaging (mpMRI) of the prostate has become an important tool, not only for the detection of prostate cancer but also for its staging(6). Imaging-based staging usually implies a morphological evaluation on T2-weighted sequences. In addition to showing the capsule, such sequences can show gross extensions as well as suspicious findings that can be indicative of microscopic ECE, such as in cases in which there is considerable contact between the neoplasm and the prostatic capsule(7). Since the advent of new MRI resources, such as the incorporation of functional methods diffusion weighted imaging (DWI), dynamic contrast-enhanced imaging, and spectroscopy there have been various studies evaluating their role in predicting microscopic ECE(8 12). More recently, studies focusing on ECE have started to include the analysis of DWI, an important component of mpMRI scans(13). Rosenkrantz et al. reported cutoff values of capsular contact for predicting any ECE, which were 7 ...

The following three major strategies were evaluated: (a) standard transrectal ultrasonography (US)-guided biopsy; (b) diagnostic MR imaging followed by MR imaging-targeted biopsy, with no biopsy performed if MR imaging findings were negative; and © diagnostic MR imaging followed by MR imaging-targeted biopsy, with a standard biopsy performed when MR imaging findings were negative. The following three MR imaging-guided biopsy strategies were further evaluated in each MR imaging category: (a) biopsy with cognitive guidance, (b) biopsy with MR imaging/US fusion guidance, and © in-gantry MR imaging-guided biopsy. Model parameters were derived from the literature. The primary outcome measure was net health benefit (NHB), which was measured as quality-adjusted life-years (QALYs) gained or lost by investing resources in a new strategy compared with a standard strategy at a willingness-to-pay (WTP) threshold of ...

To determine the degree of pain and discomfort associated with transrectal sonography (TRS)-guided biopsy of the prostate and to analyze the complications associated with this procedure. Methods. Three hundred men referred as part of an investigation to exclude prostate cancer were studied. The reasons for referral were suspected prostate cancer due to increased serum prostate-specific antigen level (,4 ng/ml), the finding of a palpable nodule or greater firmness of one prostatic lobe than the other on digital rectal examination, or the finding of a suspicious area of neoplasm of the prostate on TRS biopsy. All TRS-guided biopsies were performed as ...
Purpose: Transrectal ultrasound guided biopsy is the gold standard for detecting prostate cancer but international reports suggest that increasing risks are associated with the procedure. We estimated incidence and risk factors for infection after prostate biopsy as well as 90-day mortality using a nationwide Swedish sample.. Material and Methods: We performed a population based study of 51,321 men from PCBaSe between 2006 and 2011. Primary outcome measures were dispensed prescriptions of antibiotics for urinary tract infection and hospitalization with a discharge diagnosis of urinary tract infection. Multivariable logistic regression was used to examine risk factors for infection in men who underwent prostate biopsy.. Results: During the 6 months before biopsy the background incidence of urinary tract infection was approximately 2%. Within 30 days after biopsy 6% of the men had a dispensed prescription for urinary tract antibiotics and 1% were hospitalized with infection. The strongest risk ...

Nowadays, the majority of biopsies performed in the hospital are carried out in the Radiology department. Most of these are performed with local anaesthesia on its own or with a combination of local anaesthetic and light sedation using midazolam. Only a very small proportion of image-guided biopsies require the use of deeper sedation with a combination of midazolam and fentanyl; a general anaesthetic is almost never necessary (usually only for very painful lesions, such as an osteoid osteoma of bone).. Biopsies are performed through tiny (less than 5 mm) incisions in most cases; sutures are not required. If the patient is expected to require sedation he or she is admitted as a day case, and discharged once the sedation has worn off. When the biopsy is performed under local anaesthetic only, the patient can go home immediately after the procedure.. There are two forms of biopsy that we commonly perform: fine needle aspiration (FNA) and core biopsy.. FNA involves the use of a small calibre (23 G ...
Procedures performed by an interventional radiology specialist are becoming increasingly important in the management of patients with cancer. Although general interventional radiology procedures such as angiography and angioplasty are used in patients with and without cancer, certain procedures are reserved for the diagnosis and treatment of cancer or cancer-related complications. Interventional radiology procedures include imaging-guided biopsies to obtain samples for cytologic or pathologic testing without affecting adjacent structures. Transjugular liver biopsy is used to diagnose hepatic parenchymal abnormalities without traversing Glissons capsule. This biopsy procedure is particularly useful in patients with coagulopathies. Because the transjugular liver biopsy obtains random samples, it is not recommended for biopsy of discrete hepatic masses. Fluid collections can also be sampled or drained using interventional radiology techniques. Transcatheter chemoembolization is a procedure that delivers a
I had my first prostate biopsy back in 2008 at age 48 - it was such a negative experience that it really turned me off to the procedure and everything related to prostate cancer. Which is sad, because I had my second prostate biopsy today (at age 57) due to an alarming PSA of 16 - and I wish Id had my PSA checked at least every 2-3 years, but alas, I did not.. That said, Im still in a positive mood about things, perhaps because my doctors have been better about the entire process: in the space of about 3 weeks I had a second PSA test (which was also very high), then I had an MRI scan, which appeared to confirm the presence of cancer (but also indicated that it was localized and there was no obvious metastasis), and my biopsy today was a fusion biopsy that used the MRI results to help the doctor target the problem regions. So its been a run of bad luck so far, but I feel like my doctors have been really good about handling the diagnosis and explaining things, and so far that has helped me a ...

BACKGROUND & AIMS:Liver cT1 , liver T1 , transient elastography (TE) and blood-based biomarkers have independently been shown to predict clinical outcomes but have not been directly compared in a single cohort of patients. Our aim was to compare these tests prognostic value in a cohort of patients with compensated chronic liver disease. METHODS:Patients with unselected compensated liver disease aetiologies had baseline assessments and were followed up for development of clinical outcomes, blinded to the imaging results. The prognostic value of noninvasive liver tests at pre-specified thresholds was assessed for a combined clinical endpoint comprising ascites, variceal bleeding, hepatic encephalopathy, hepatocellular carcinoma, liver transplantation and mortality. RESULTS:One hundred and ninety-seven patients (61% male) with median age of 54 years were followed up for 693 patient-years (median (IQR) 43 (26-58) months). The main diagnoses were NAFLD (41%), viral hepatitis (VH, 25%) and alcohol-related
Malignant melanoma of the mandibular gingiva is extremely rare. It is a malignant tumour of melanocytes or their precursor cells, and often misinterpreted as a benign pigmented process. A few reports have described computed tomography (CT) and magnetic resonance imaging (MRI) findings of malignant melanoma in the oral cavity. We report a rare case of malignant melanoma of the mandible and the related CT and MRI findings. Soft tissue algorithm contrast-enhanced CT showed an expansile mass and irregular destruction of alveolar bone in the right side of the mandibular molar area. MR images showed an enhancing mass and the tumour had a low to intermediate signal intensity and a high-signal intensity. Soft tissue algorithm contrast-enhanced CT and MR images showed lymphadenopathy involving the submandibular lymph nodes. Histopathological examination confirmed the diagnosis of malignant melanoma ...

Prostate Magnetic Resonance Imaging (MRI) Michael S. Leapman, M.D. 12/2015 What is a Prostate MRI? Magnetic resonance imaging (MRI) is a method for visualizing soft tissue structures in the body. Images are generated by MRI scanners using magnetic fields instead of x-rays or other forms of radiation. When applied to imaging of the prostate, MRI offers advantages in identifying potentially significant aggressive prostate cancers and recent advances in technology also facilitate directlesion targeted biopsy. What is a Fusion Biopsy? Fusion MRI-ultrasound biopsy is a technique that overlays previously acquired MRI images of the prostate with real-time transrectal ultrasonography (TRUS) to allow clinicians to directly target suspicious areas identified on MRI. It combines ability to target in real-time ultrasound with the more detailed MR images to allow for a more accurate diagnosis of prostate cancer. The technique involves acquisition of the MR images that are reviewed by experienced radiologists ...
We found 3 main themes that largely determine whether and how communication about TM/CAM takes place between patients and their primary care clinicians: acceptance/nonjudgment, initiation of communication, and safety/efficacy concerns. Patients perspectives about TM/CAM communication were clear and consistent. Most patients who are using TM/CAM for health or illness expect the clinician to initiate the discussion on this topic if communication is to occur. Patient data suggested clinician initiation, when carried out in a nonjudgmental fashion, would demonstrate openness to TM/CAM and would help patients overcome anticipated or previous negative interactions in discussions about TM/CAM. Patients usually did not expect their clinicians to be experts on the TM/CAM they were using.. Paradoxically, some clinicians interpreted the low levels of communication about TM/CAM as a sign of low use in their clinical practices. This assumption, together with the clinicians lack of understanding about ...
My research proceeds from the idea that the foundation of mental health and mental illness is social; thus mental health care must include attention to the patient (or client) as a person living in society and in relationship with others. In the 1990s I studied mental health outreach to people who are homeless (outreach work). In outreach work, clinicians leave their offices to find, make contact, and build trust with people who, often, are avoiding contact with mental health professionals due to their previous negative experiences with them. Outreach workers move at the clients pace, gradually introducing a range of services including primary care, access to entitlement income, and housing, hoping eventually to persuade people to accept mental health care. While the encounters between homeless people and outreach workers are clinical encounters, I see them, also, as social encounters taking place at the psychological, socioeconomic, and physical boundaries of society. These social encounters ...
From hazard mitigation and strategic planning to the urgent deployment of resources in response to major disasters, public safety comprises a major component of local, state and federal government administration. Response to natural disasters like Superstorm Sandy on the Atlantic coast, wildfires in the west or implications of potentially harmful virus outbreaks all present unique and unpredictable challenges to police, fire, EMS and military agencies at all levels. Acts of terror, such as the Charleston Church Massacre and Orlando nightclub shootings, challenge our efforts to prevent danger, minimize its effects and respond efficiently and effectively when necessary. Security is not just a federal responsibility; local and state agencies share responsibility. Noble public administrators are entrusted to protect and serve citizens on a daily basis. But what are the public administration implications when such trust is compromised by previous negative community relationships, civil protest and ...
Background Prostate cancer (PCa) diagnosis by means of multiparametric magnetic resonance imaging (mpMRI) is a current challenge for the development of computer-aided detection (CAD) tools. An innovative CAD-software (Watson Elementary (TM)) was proposed to achieve high sensitivity and specificity, as well as to allege a correlate to Gleason grade. Aim/Objective To assess the performance of Watson Elementary (TM) in automated PCa diagnosis in our hospitals database of MRI-guided prostate biopsies. Methods The evaluation was retrospective for 104 lesions (47 PCa, 57 benign) from 79, 64.61 +/- 6.64 year old patients using 3T T2-weighted imaging, Apparent Diffusion Coefficient (ADC) maps and dynamic contrast enhancement series. Watson Elementary (TM) utilizes signal intensity, diffusion properties and kinetic profile to compute a proportional Gleason grade predictor, termed Malignancy Attention Index (MAI). The analysis focused on (i) the CAD sensitivity and specificity to classify suspect lesions ...

Induced pluripotent stem cell-derived neural stem cells (iNSCs) have significant potential as an autologous, multifunctional cell therapy for stroke, which is the primary cause of long term disability in the United States and the second leading cause of death worldwide. Here we show that iNSC transplantation improves recovery through neuroprotective, regenerative, and cell replacement mechanisms in a novel ischemic pig stroke model. Longitudinal multiparametric magnetic resonance imaging (MRI) following iNSC therapy demonstrated reduced changes in white matter integrity, cerebral blood perfusion, and brain metabolism in the infarcted tissue. The observed tissue level recovery strongly correlated with decreased immune response, enhanced neuronal protection, and increased neurogenesis. iNSCs differentiated into neurons and oligodendrocytes with indication of long term integration. The robust recovery response to iNSC therapy in a translational pig stroke model with increased predictive potential ...

Hi, does anyone know why D2 biopsies would be taken? Is this routine? I was told everything looks normal but so worried as to why they ve taken them it s going to be a long 10days waiting on results.

இந்த கட்டுரையை எழுதும் போது என்னை பார்க்க வந்த ஒரு நோயாளியை பற்றி இங்கு குறிப்பிட விரும்புகிறேன்: சுமார் 60 வயது மதிக்க அவர், ஒரு நுரையீரல் புற்றுநோயாளி, அவருக்கு ஆங்கில மருத்துவத்தில் கொடுத்த சிகிச்சை, ஸ்கேன் செய்து விட்டு Biopsy test என்னும் பெயரில் அந்த கான்சர் கட்டியின் ஒரு பகுதியை வெட்டி உள்ளனர். பின்பு இதனை சரிசெய்ய முடியாது என்று கூறி அனுப்பி விட்டனர். ஏன், இந்த நோயை ஆங்கில ...
