WebPatients with a creatinine level less than 3 mg/dl were divided into a control group without renal diseases and three groups with different underlying renal diseases: diabetic nephropathy, chronic glomerulonephritis, and nephrosclerosis. WebFeb 17, 2024 · The resistive index (Pourcelot index) is a calculated flow parameter in ultrasound, derived from the maximum, minimum, and mean Doppler frequency shifts during a defined cardiac cycle. Along with the pulsatility index (PI), it is typically used to assess the resistance in a pulsatile vascular system. RI = ( PSV - EDV) / PSV WebResistive index. A resistive index (RI) is also available which is calculated by subtracting the end-diastolic velocity from the peak systolic velocity, and then dividing that by the peak systolic velocity. 52 The interlobar and the arcuate arterial beds in the kidney are the insonation target in this measurement, and a commonly used normal ... lakeville youth volleyball
