Background The arterial vascularity of the hip has been investigated in normal infants using duplex Doppler sonography. This study addressed the differences in hip vascularity in infants with respect to gender and acetabular morphology.... more
Color flow mapping systems have become widely used in the short time since their development. These systems overlay a pseudo-color velocity map upon the gray-scale two-dimensional image. Between 4 and 16 pulses are directed to each... more
Objective To determine the role of transrectal power Doppler ultrasonography (PDU) in the diagnosis of prostate cancer. To determine the role of transrectal power Doppler ultrasonography (PDU) in the diagnosis of prostate cancer.Patients... more
Objective To evaluate the relationship between power Doppler ultrasonography (PDUS) assessment and clinical variables including enthesitis index, pain threshold and disease activity parameters, and to document grey-scale US findings of... more
Pancreatic pseudoaneurysm rupture is a rare complication of chronic pancreatitis, with severe prognosis and high mortality. Angiography is usually required for confirmation of the diagnosis, but transabdominal ultrasound and CT... more
The objective was to evaluate whether three-dimensional ultrasonography (3D-US) and power Doppler angiography (PDA) measurements can predict ovarian response and/or are associated with IVF/ICSI outcome. A prospective clinical study in 65... more
Ultrasound contrast agents (UCAs) are small micro-bubbles that behave nonlinearly when exposed to an ultrasound wave. This nonlinear behavior can be observed through the generated higher harmonics in a back-scattered echo. In past years... more
Purpose.To examine synovial vascularity and flow patterns in hand and wrist joints—metacarpophalangeal (MCP) joints and ulnar stiloid (USTL) regions—of patients with rheumatoid arthritis (RA) using power Doppler sonography (PDUS) and... more
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... more
OBJECTIVE:Use of new echo enhancers capable of passing the lung filter has extended the clinical applications of color power Doppler flow imaging in many diseases and appears promising in the study of neoplasm vascularization. Levovist... more
We test the hypothesis that first-trimester serum analytes, 4-D power Doppler placental vascular indices and uterine artery Doppler (UAD) predicts abnormal placental morphometry in pregnancies with preeclampsia (PE) and fetal growth... more
