Renal Vascular Perfusion Index in a Canine Model [PDF]
Ultrasound in Medicine & Biology, 2009 Decreased renal perfusion plays an important role in the progression toward renal failure. In this study, a novel measure was proposed to quantify renal perfusion using canine model. Serial renal vascular images at different vascular areas including the whole vascular tree, interlobar, arcuate and interlobular vessels were captured.
