First-Pass Whole-Body Magnetic Resonance Angiography at 3T with the Blood-Pool Contrast Agent Gadofosveset and the Extracellular Contrast Agent Gadoterate: A Randomized Study.

Whole-body magnetic resonance angiography (WB-MRA) can depict arterial stenoses in a large part of the body in one fast examination. We investigated the feasibility of 3T WB-MRA using the built-in body coil for signal acquisition. Two different contrast agents (a standard extracellular agent and a blood-pool agent) were used in a randomized manner. A total of 16 patients with symp-tomatic peripheral arterial disease were examined. DSA served as method of reference. Sensitivity and specificity for detecting significant arterial stenoses with the used WB-MRA method was mod-erate to high for both contrast agents. Interobserver agreement for WB-MRA was good.
