Two- and three-dimensional transvaginal ultrasound with power Doppler angiography and gel infusion sonography for diagnosis of endometrial malignancy.
OBJECTIVES To evaluate the diagnostic efficiency of two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasonography, power Doppler angiography (PDA) and gel infusion sonography (GIS) at offline analysis for recognition of malignant endometrium compared with real-time evaluation during scanning, and to determine optimal image parameters at 3D analysis. METHODS One hundred and sixt...

15 صفحه اولFetal cardiac flow velocities in the late 1st trimester of pregnancy: a transvaginal Doppler study.
In 30 normal women with a singleton pregnancy, transvaginal Doppler ultrasound was used to record flow velocity at the fetal atrioventricular (AV) valve and outflow tract levels (ascending aorta and pulmonary artery) at 11 to 13 weeks of gestation. Technically acceptable flow velocity waveforms were recorded at the AV valve level in 19 fetuses and in the ascending aorta and pulmonary artery in ...
متن کاملVirtual angiography of the fetal brain using postmortem MRI.
Recently, Postmortem MRI imaging is used to replace traditional invasive autopsy examination. This may be an alternative in the 40% of cases which cannot be autopsied because of parental demand to protect the integrity of their fetus, or when standard autopsy is not available. Cerebral sinovenous thrombosis (CSVT) is a rare and significant condition in fetuses and is mostly diagnosed late durin...
متن کاملCervical Volume and Flow Indices during Pregnancy by Transvaginal 3-dimensional Ultrasonography and Doppler Angiography
Recent studies have shown that transvaginal ultrasound provides a more reliable and objective evaluation of the uterine cervix, demonstrating that the shorter the length of the cervix the higher the risk of preterm delivery. Measuring cervical volume could even be a better reflection of cervical morphology. Three-dimensional (3D) imaging combined with power Doppler, theoretically provides the p...
