The purpose of this study was to intraindividually compare static, high resolution and dynamic CE MRA of the lower legs in patients with severe peripheral arterial occlusive disease (PAOD). State of the art 4D MRA of the lower legs for suspected PAOD provides excellent image quality without venous overlay, an artefact that severely influences diagnostic quality in static MRAs. It is user independent proven by a Cohen´s kappa of 0.92. 4D MRA of the lower legs should be employed in all patients undergoing CE MRA for suspected PAOD.
