High spatial resolution arterial-only frames are desired in time-resolved 3D CE-MRA of the hands and feet. However, the increased spatial undersampling used for acceleration generally causes a reduction in image quality. In this work dedicated eight- and twelve-element peripheral vascular coil arrays were developed to maintain high image quality for accelerations greater than an order of magnitude (>10x). Results demonstrate high diagnostic image quality for high spatial and temporal resolution, bilateral 3D CE-MRA of the hands and feet.
