[MR angiography of the lower extremities with an automatic table translation (Mobitrak) compared to i.a. DSA].
OBJECTIVE
Comparison of the diagnostic information obtained by MRA using a moving bed ("MobiTrak") with i.a.DSA for angiography of the lower extremities.


METHODS
In 20 patients, i.a.DSA and MRA were performed within a few days. The image quality and diagnostic information were evaluated by two radiologists and two surgeons.


RESULTS
The radiologists assessed the quality of MRA higher for 18%, for 79% image quality was equal, for 3% the quality was graded as lower in comparison to i.a.DSA. The surgeons found the quality of MRA higher for 16%, equal for 75% and lower for 9%. In all cases, MRA was sufficient for planning of further treatment.


CONCLUSIONS
For examinations of the arterial vessels of the lower extremities, MRA with a moving bed ("MobiTrak") can be used instead of i.a.DSA. The diagnostic information from MRA is sufficient for planning the further treatment. The advantages of MRA (no radiation, no i.a. puncture, no contrast medium with iodine) will lead to an increasing application of this method.
