Herein, we present a new method for the performance of percutaneous transluminal renal angioplasty (PTRA) guided by non-contrast magnetic resonance angiography (NATIVE True FISP) overlaid on intra-procedural fluoroscopy images. This novel overlay system led to sufficient visualization as the overlaid vasculature on the live fluoroscopic image, and enabled the safe completion of PTRA with fewer angiographic procedures, thus requiring lower volumes of iodinated contrast material and shorter fluoroscopic times.
