Objective: Detection and evaluation of adrenal glands are complex problems in conventional ultrasonography in dogs. Using three-dimensional (3D) ultrasonography (US) in adrenal gland volume evaluation can add new potential for further adrenal studies. Design: Descriptive study Animals: a total of 10 mix breed dogs Procedures: The dogs underwent two dimensional (2D) and 3D US of the adrenal g...

Three-dimensional (3D) ultrasonography has been shown to be an accurate and appropriate tool for measurement of gallbladder volume in humans. Therefore, we applied this novel technique for the first time to study fasting and postprandial gallbladder volume in 10 healthy dogs and compared the results with those of 2-dimensional (2D) ultrasonography. Fasting gallbladder volumes determined by 3D u...

A prospective study was conducted at the OB/GYN department of Kasr El Eini hospital, Cairo University from Jan 2000 - Oct 2002. The study included 51 patients in the age group between 40-70 years (including pre and post menopausal women). All patients were subjected to following after taking a consent from each patient: Complete clinical evaluation; including history taking and clinical examina...

Our objective was to determine the accuracy of three dimensional (3D) ultrasonography in the differentiation of ovarian tumours. Women (n = 20) with ovarian tumours (13 benign and seven malignant) were first examined using two-dimensional (2D) ultrasonography and were then evaluated with three-dimensional (3D) ultrasonography. All patients underwent surgery within 7 days of 2D and 3D ultrasonog...

OBJECTIVE Patient characteristics, CA125 level and two-dimensional (2D) ultrasonography can be used to predict the probability of malignancy of an ovarian mass. Three-dimensional (3D) ultrasonography might also contribute to the prediction of malignancy. We evaluated whether addition of 3D features to a diagnostic model could improve the discriminative capacity of the model. METHODS This mult...

A review and update on tridimensional ultrasonography covering all its aspects, ultrasonography and 3D endoscopic ultrasonography, its technical details and current indications, such as volume calculation, vascular architecture assessment, and role in interventionist ultrasounds. Images included are from the author's own experience.

Objective: to compare the estimated thyroid volume, as determined by two-dimensional (2D) and three-dimensional (3D) ultrasonography, with real volume. Design: Descriptive Study Animals: A total of 7 mixed breed dogs Procedures: On 2D ultrasound, the thyroid volume is estimated by the ellipsoid equation and on 3D ultrasound; it is estimated by outlining the boundaries of the thyroid lobe in ...
