Preoperative vascular evaluation of living renal donors Gadolinium-enhanced magnetic resonance angiography [MRA] versus conventional renal angiography

The aim is to assess the accuracy and sensitivity of Magnetic Resonance Angiography [MRA] in preoperative vascular evaluation of living renal donors. Twenty five individuals [donors] coming up for renal donation, eleven related and fourteen unrelated donors with ages between 20-45 years. Each donor had 3D MRA as an outpatient procedure and intra-arterial DSA [Digital Subtraction Angiography] as an inpatient procedure. The operative findings were considered as a standard for comparison between MRA and DSA results. No difference was found between MRA and DSA. The accuracy of MRA when compared with operative finding was 96%. MRA is a non-invasive, accurate and pretty safe procedure for the evaluation of healthy renal donors
