Non-contrast renal MRA using an inflow inversion recovery SSFP sequence (Inhance) was performed in additiona to 3D CE MRA in 24 patients referred for renal MRA. Inhance images were of good-excellent quality in nearly all cases, and demonstrated good agreement with CE MRA for detection of significant renal artery stenosis. Our results suggest that this technique may be effective in investigating suspected renovascular disease in patients who have contraindications to gadolinium-based contrast agents.
