Renal artery stenosis (RAS) has been associated with hypertension, chronic kidney disease and an increased risk of vascular events. This study quantitatively compares two non-contrast enhanced magnetic resonance angiography (NC-MRA) techniques for renal angiography, based on SNR, CNR, vessel sharpness and number of renal branches. TIR has shown promising results in suppressing background signal and provided overall better image quality than outflow time-SLIP. TIR has the advantage over time-SLIP that tissues can be nulled over a wide range of T1 -values. To further shorten scan time the TIR technique could be combined with more advanced image based motion correction techniques.
