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 …

PURPOSE: To evaluate the modifications of Doppler ultrasound waveform morphology after
inhibition of angiotensin-converting enzyme with captopril to increase the sensitivity of …

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 aim of this study was to determine the accuracy of direct and indirect parameters for the
diagnosis of renal artery stenosis and to determine the most useful thresholds for these …

Abstract purpose: The purpose of this study was to determine the sensitivity, specificity, and
clinical usefulness of renography performed in combination with captopril administration …

This study identified the extent of inter-and intraobserver variation in assessing intrarenal
Doppler waveform parameters. Optimized Doppler waveforms from the interlobar arteries of …

Because of the success of Doppler sonography in the carotid arteries, original efforts at
detecting renal artery stenosis were focused on similar Doppler parameters. Criteria …

The renal arteries of 40 patients without renal or renovascular disease were examined with
duplex real-time Doppler sonography. Special views were employed to obtain adequate …

In arteries, such as the internal carotid artery, that are easily insonifled, stenoses are very
well detected through identification of the increased velocity they produce. Application of this …

Slowing and dampening of systole in the arterial network distal to stenosis is a well-known
Doppler sign of severe arterial stenosis. To determine whether this sign is present in boys …
