A method combining an interleaved variable density (IVD) Cartesian acquisition with a reconstruction that integrates HYPR and parallel imaging is applied to peripheral run-off MRA. The method is compared to conventional view sharing in normal volunteers, demonstrating improved spatial resolution and temporal fidelity. Preliminary clinical results in patients with peripheral vascular disease are also presented.
