• organs
  • They generally develop on normal or fatty liver, are single or multiple (generally paucilocular), have distinct delineation, with increased echogenity (hemangiomas, benign focal nodular hyperplasia) or absent, with posterior acoustic enhancement effect (cysts), have distinct delineation (hydatid cyst), lack of vascularization or show a characteristic circulatory pattern, displace normal liver structures and even neighboring organs (in case of large sizes), are quite elastic and do not invade liver vessels. (wikipedia.org)
  • It is used to see internal body structures such as tendons, muscles, joints, blood vessels, and internal organs. (wikipedia.org)
  • biometry
  • Because of there was not significant difference between the biometry of the both eyes, the measurements of the ocular structures are the mean and standard deviation of 40 eyes. (vin.com)
  • The axial length (AL) is the distance between the anterior surface of the cornea and the fovea and usually measured by A-scan ultrasonography or optical coherence biometry. (wikipedia.org)
  • uterine
  • More recently 3-D ultrasonography has been advocated as an excellent non-invasive method to evaluate uterine malformations. (wikipedia.org)
  • The uterine appendages or (adnexa of uterus) are the structures most closely related structurally and functionally to the uterus. (wikipedia.org)
  • Compared to ICC, the measurements of the aforementioned extrafoetal structures give a less accurate prediction, because the uterine wall and foetal membranes are characterized by less defined margins than those of the chorionic cavity (Luvoni, Grioni 2000). (vin.com)
  • spleen
  • However, because spleen size varies greatly, ultrasonography is not a valid technique for assessing spleen enlargement and should not be used in typical circumstances or to make routine decisions about fitness for playing sports. (wikipedia.org)
  • Superficial
  • Superficial structures such as muscles, tendons, testes, breast, thyroid and parathyroid glands, and the neonatal brain are imaged at a higher frequency (7-18 MHz), which provides better axial and lateral resolution. (wikipedia.org)
  • contrast
  • In contrast to arterial ultrasonography the wall of the vein is not relevant and importance is given to the hemodynamic conclusions that the examiner can obtain in order to provide a valuable report. (wikipedia.org)
  • assess
  • To assess the feasibility of integrating ultrasonography into the first-year and second-year OMM curriculum through the evaluation of students' success in demonstrating the technology and visualizing the anatomy. (jaoa.org)
  • It makes it easier to assess damage done to these structures. (wikipedia.org)
  • study
  • In all 3 study phases, ovarian specimens will be imaged first with 2D and 3D ultrasonography and then with the Biomedical Imaging and Therapy Beamline (BMIT) at the Canadian Light Source. (clinicaltrials.gov)
  • procedure
  • Ultrasonography as a single procedure is usually performed without the need for sedation or anaesthesia, so the owner can sit and wait while the procedure is performed, and gain results immediately. (elandsvet.co.uk)
  • various
  • Drawbacks of ultrasonography include various limits on its field of view including patient cooperation and physique, difficulty imaging structures behind bone and air, and its dependence on a skilled operator. (wikipedia.org)
  • application
  • the application of ultrasonic waves to therapy or diagnostics, as in deep-heat treatment of a joint or in ultrasonography. (thefreedictionary.com)
  • The mean value of the data obtained from the measurement of each structure on different fetuses is calculated and the predicted day of parturition is obtained by the application of equations. (vin.com)
  • uterus
  • This uterus may or may not be connected to Müllerian structure on the opposite site if the Müllerian duct on that site undergoes some development. (wikipedia.org)
  • depth
  • The heights of the reticular crests and depth of the structures vary across ruminant animal species. (wikipedia.org)
  • Other limitations of ultrasonography for imaging the ovaries include a limited depth of penetration within the pelvis and the inability to see the ovaries clearly due to bowel activity and/or gas. (clinicaltrials.gov)
  • known
  • Portal venography is the definitive method for demonstrating PSS, but is invasive, hence it is best reserved for animals with a known shunt or those considered highly likely to have a shunt that was not detectable by ultrasonography. (wikipedia.org)
