WebJan 2, 2024 · The RI can be calculated by subtracting the end-diastolic velocity from the PSV and dividing that number by the PSV. We have not found RI analysis to be valuable in the evaluation for renal artery stenosis as the RI may be elevated in numerous conditions, including parenchymal renal disease, acute tubular necrosis, pyelonephritis, renal vein … WebOhm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: =, where I is the current through the conductor, V is the voltage measured …
