WebGreg J. McKenna, Göran B.G. Klintmalm, in Transplantation of the Liver (Third Edition), 2015 Hepatic Artery The resistive index (RI) assesses the ratio of the upstroke of the systolic wave in the hepatic artery to the end-diastolic flow rate, and normal initial posttransplant RI should be 0.6 to 0.9. WebThe authors prospectively evaluated the accuracy of the resistive index (RI) in Doppler ultrasound (US) for the detection of the increased vascular resistance that theoretically occurs with acute liver transplant rejection. RIs were calculated for the proximal hepatic artery and a more distal hepatic artery branch in 67 liver transplant recipients. Biopsies …
