Complete evaluation of both large and small vessel status would typically require two separate contrast enhanced acquisitions: MR angiography and dynamic contrast enhanced (DCE) perfusion. Both the MRA and quantitative DCE perfusion could be obtained simultaneously if a 3D time-resolved contrast enhanced data set could be acquired in a manner that the contrast and spatial/temporal resolution requirements for both exams could be met. This study demonstrates feasibility and repeatability of simultaneous MRA and perfusion (MRAP) with a time resolved MRA acquisition, and initial application for leg angiography and quantitative skeletal muscle perfusion at rest and following a physiological stimulus (exercise).
