From: Ratio of diastolic to systolic blood pressure represents renal resistive index
Schema to show the studied four renal regions and the concept of renal resistive index. The studied four regions from the proximal to the distal are as follows: trunk, hilum, segmental, and interlobar. EDV end-diastolic velocity, LPP pole-to-pole kidney length, PSV peak systolic velocity, RRI renal resistive index
