PURPOSE: The utility of Doppler parameters and waveform contour analysis for diagnosis of
renal artery stenosis was studied in a hypertensive population screened for renovascular …

The clinical use of ultrasonic echo Doppler velocimetry as a screening test for renal artery
stenosis was investigated in 11 control subjects and 20 hypertensive patients including 10 …

The measurement of resistive index (RI=[peak systolic velocity− end diastolic velocity]/peak
systolic velocity) by Doppler sonography has demonstrated variable reliability as an …

Previous studies of transplant kidneys and recent reports on native kidneys have suggested
intrarenal arterial Doppler findings can be helpful in the noninvasive workup of renal vein …

The goal of this study was to assess the value of quantitative and qualitative analysis of the
early systolic rise on Doppler waveforms obtained before and after administration of …

Background We examined the most widely used echo-Doppler variables in healthy adults to
define their normal distribution and variability in relation to age, sex, body surface area and …

The flow velocity pattern in the descending aorta, renal arteries, and celiac and superior
mesenteric arteries was studied with pulsed Doppler in eight premature babies with …

Recent clinical studies using duplex Doppler sonography identified an alteration in renal
arterial blood flow in obstructed hydronephrotic kidneys that reportedly can be used to …

This report compares six Doppler ultrasound measures of blood flow: Pourcelot's pulsatility
index, Gosling's pulsatility index, area under the curve, systolic amplitude, diastolic …

Background/Purpose: It is difficult to detect the arcuate or cortical renal arteries when
performing pulsed Doppler sonography (PDS) for congenital hydronephrosis. This study …
