Dual-station calf-foot bolus chase MRA with high spatial (<1.0 mm isotropic) and high temporal (2.4-6.6 sec) resolution is demonstrated in volunteers. Real-time reconstruction of diagnostic 3D calf arteriograms is used to precisely trigger table motion to the foot station. High quality arteriograms without confounding venous contamination can be acquired over the extended field-of-view with resolution competitive with single-station methods.
