An International Multicenter Comparison of Time-SLIP Unenhanced MR Angiography and Contrast-Enhanced CT Angiography for Assessing Renal Artery Stenosis: The Renal Artery Contrast-Free Trial

Abstract

Compared with contrast-enhanced CTA, the unenhanced MRA technique time-SLIP shows promise for assessing the renal arteries for stenosis. The unenhanced MRA technique time-SLIP may provide a safe alternative for evaluating the renal arteries for stenosis.
