AIM To determine whether introducing three-dimensional (3D) ultrasonography with power Doppler facilities as a secondary screening test, preceded by annual transvaginal grayscale ultrasonography (TVUS) (followed by transvaginal color Doppler (TVCD) in selected cases) as a primary screening test for ovarian cancer improves the accuracy of ovarian cancer screening studies. METHODS Annual TVUS w...

OBJECTIVE: To evaluate the interobserver reproducibility of vascular indices obtained with three-dimensional power Doppler (3D power Doppler) ultrasonography at the first trimester of gestation. MATERIALS AND METHODS: The present reproducibility study involved 32 healthy pregnant women with 7 to 10 weeks and 6 days of gestation. The VOCAL (Virtual Organ Computer-aided AnaLysis) method was utili...

Aneurism of the vein of Galen is a complex arteriovenous malformation which is of multiply communications between of the vein of Galen and the cerebral arteries. It represents less than 1% of the cerebral arteriovenous malformations. Few cases using three-dimensional (3D) power and color Doppler ultrasound have been reported in the literature. We present a case of an aneurysm of the vein of Gal...

OBJECTIVE To estimate whether three-dimensional ultrasonography and three-dimensional power Doppler investigation can contribute to the differentiation between benign and malignant ovarian masses. METHODS Women scheduled for surgical treatment of an adnexal mass were included in a multicenter prospective study. All women underwent two-dimensional and three-dimensional ultrasonographic examina...

Choriocarcinoma is a highly malignant disease of trophoblastic cells, which affects young women in the reproductive years. The main sites of metastasis from choriocarcinoma are lung, vagina, liver, gastrointestinal tract and kidneys, and the involvement of the ovaries is extremely rare. The diagnosis of ovarian metastasis is made mainly by two-dimensional ultrasonography (2DUS) with color Doppl...

this study was conducted to determine the use of three-dimensional ultrasonography (3du) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3du of the eyes were done using a 5–12 mhz linear trapezoid transducer. 3du of the eyes were evaluated and the normal optical long axis through a line between the cornea ...
