[MR angiography of pelvic and leg vessels with automatic table movement technique ("Mobi-Trak")--clinical experience with 450 studies].
OBJECTIVE
By a retrospective clinical evaluation of 450 MR angiograms of the lower extremity arteries the question was posed of whether MR angiography can replace i.a. DSA.


METHODS
Image quality of 450 MR angiograms was graded by 4 radiologists; in 102 patients who underwent radiological intervention a comparison between MR angiogram and i.a. DSA was done. Additionally, MR angiography was compared with the results of surgical intervention in 106 cases.


RESULTS
6% of 450 examinations showed a significant limitation of diagnostic information. 5 examinations (1%) had to be redone by i.a. DSA. In all cases the diagnosis from MRA was proven by the results of the following i.a. DSA or surgical procedure.


CONCLUSIONS
The retrospective clinical evaluation of 450 examinations demonstrated that MR angiography of the lower extremity arteries can replace i.a. DSA in routine use.
