Normal renal artery velocity ultrasound

Web1 de dez. de 1993 · Doppler parameters measured in the distal renal artery included systolic acceleration, acceleration time, peak systolic velocity, deceleration in late systole, pulsatility and resistivity indexes, and waveform features in early systole. RESULTS: Angiograms demonstrated 28 stenotic renal arteries. WebThe RIR is the best velocity parameter in the detection of RAS (≥50%), and its best cutoff is 5. Valuing influencing factors of PSV in the renal artery will help reduce misdiagnosis. The combination of RIR greater than 5 and PSV less than 15 cm/s in the interlobar artery provides the best diagnostic efficiency of RAS.
