AAPM/RSNA physics tutorial for residents: topics in US: beyond the basics: elasticity imaging with US.
A new mode of imaging with ultrasonography (US) is under development in several laboratories around the world. This technique allows estimation of some measure of the viscoelastic properties of tissue. The information displayed in the images is a surrogate for that obtained with manual palpation. Fundamental concepts in elasticity imaging include stress, strain, and the elastic modulus; strain ...
متن کاملThe role of ultrasonography (US), Doppler US artifacts and elastography in the detection of foreign bodies
Purpose: The aim of the study is to characterize the ultrasound and Doppler ultrasound artifact patterns of foreign bodies and to define the role of elastography in their detection. Material and method: Two in-vitro environments including a lamb leg and a lamb stomach coated with ultrasound gel, were prepared. Twenty-seven foreign bodies grouped as metallic, organic and inorganic were evaluated...
متن کاملColor Doppler US in the evaluation of uterine vascular abnormalities.
Uterine vascular lesions are rare but potentially life-threatening lesions that should be suspected in women of reproductive age with unexplained vaginal bleeding and in postmenopausal women in whom anechoic structures are detected at ultrasonography (US). This is especially true in patients with a history of infection, curettage, therapeutic abortion, pelvic surgery, endometrial carcinoma, or ...
متن کاملDoppler US evaluation of renal biopsy complications in children.
PURPOSE Percutaneous renal biopsy plays an important role in the diagnosis and management of renal disease in children, but it does carry some complications. As most cases are vascular in origin, Doppler ultrasonography (US) has clear benefits in terms of detecting bleeding and assessing vascular damage. The aim of this study was to investigate the effectiveness of Doppler US in detecting possi...
متن کاملGray-scale and color Doppler US findings of amniotic sheets.
PURPOSE To identify the gray-scale and color Doppler ultrasonography (US) findings of amniotic sheets. MATERIALS AND METHODS Among 1201 pregnant patients who underwent detailed second trimester US, nine had amniotic sheets. An amniotic sheet was defined as a shelf-like structure in the uterine cavity with a free edge not attached to the fetus or umbilical cord. There was no major fetal anomal...
