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...

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...

conclusion following splenectomy, thrombocytosis can predispose the patients to an increase in cerebral blood velocities more than respected with anemia. but by transcranial doppler ultrasonography no evidence of significant stenosis were found in intracerebral arteries to conclude that the beta-thalassemia major patients were more prone to the development of stroke secondary to this abnormalit...

conclusion our study revealed that the hypoplastic umbilical artery group’s non-dominant cia had higher ri values than the contralateral dominant cia. results eleven of the 165 patients (6.7%) demonstrated a hypoplastic umbilical artery. second-trimester us showed median dominant and non-dominant cia pi values of 1.43 and 1.60 (p = 0.062), respectively, and median dominant and non-dominant cia ...

Background: To investigate difference in intratesticular arterial pulsatility index (PI) and resistance index (RI) between varicocele and healthy testes using power Doppler ultrasonography. Materials and Methods: Patients undergoing scrotal ultrasonography were recruited. PI and RI of the intratesticular artery were measured using a 12-MHz power Doppler ultrasound, and varicocele grades were ob...
