To date, no prospective randomized trial comparing peripheral CE-MRA at 3T to the reference standard DSA has been performed so far including a large patient population. This multicentre trial including 189 patients was primarily aimed to compare the degrees of agreement in stenosis detection between contrast enhanced-MRA and DSA using two different contrast agents (gadoterate meglumine (Dotarem) or gadobutrol (Gadovist)) inpatients with peripheral arterial occlusive disease (PAOD). This study demonstrates the value of peripheral MRA at 3T for diagnosis and treatment planning in patients suffering from PAOD without any difference between gadoterate meglumine-MRA and gadobutrol-MRA.
