OBJECTIVE To present the appearance of the fetal akinesia deformation sequence by three-dimensional ultrasonography after four-dimensional ultrasonographic scanning. METHODS Three-dimensional surface-rendering images were used to show the fixed postural abnormalities of the fetal extremities and body. Four-dimensional ultrasonography was used to show that the postural abnormalities were fixed...

Objective- To determine the possibility and reproducibility of three-dimensional ultrasonography (3DUS)and comparison of the achieved measurements to normal two-dimensional ultrasonography (2DCS)Design- Descriptive studyAnimals- 10 young mixed normal dogs, age 1.5-2.5 year, weighing 9.7-12 kg Procedure- Renal width, length, and depth measured in coron al and transverse sections. The measurement...

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...

Three-dimensional ultrasonography is a significant novelty in neurosonology as it offers the possibility of an even more successful evaluation of atherosclerotic stenoses of the carotid trunk than previous ultrasonographic investigations. In 37 patients with signs of transitory ischemic attack and in 5 patients with reversible ischemic neurologic deficit we compared the findings of three-dimens...

Today’s ultrasound imaging systems produce better images and display more information than it was possible to display 30 years ago. Similarly, performance criteria for ultrasound imaging systems and the tools used to make these measurements have evolved, and have become more complex. This presentation will informally discuss a few examples of the evolution of ultrasound imaging systems and perf...

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...

PURPOSE To assess the feasibility of applying trans-applicator intracavitary ultrasonography to image-guided brachytherapy for cervical cancer. MATERIAL AND METHODS For this experiment, a phantom was created and included a polyethylene tube, intended to simulate a tandem applicator, which was inserted into chicken meat and embedded in agar, along with magnetic resonance imaging (MRI)-compatib...
