An investigational version of inflow inversion recovery fast spin echo (IFIR-FSE) is the technique of non-contrast enhanced MR angiography (NC MRA) based on inflow effect during inversion time of inversion recovery. We investigated usefulness in assessment of supraaortic arteries of NC MRA with IFIR-FSE in comparison of NC MRA with 3D time of flight and dynamic contrast-enhanced MRA in twenty patients. NC MRA with IFIR-FSE could visualize large areas of the supraaortic arteries with good image quality and showed high negative predict value for detection of vascular stenoses. This technique can be used as a screening method in this area.
