OBJECTIVES: To assess to what extent results of CE-MRA coincide with DSA in grading of stenosis and planning of therapy in patients with PAOD.
MATERIALS AND METHODS: Retrospectively, images of 71 PAOD-patients were studied by three observers. For evaluation, the lower limb was subdivided into 31 segments and categorized with TASCII-score.
RESULTS: In grading stenosis, both modalities agreed in 93.26%. CE-MRA achieved sensitivity of 92.69% and specificity of 96.87% (κ = 0.88). The concordance of TASCII-classification was almost perfect.
CONCLUSION: CE-MRA is an excellent method for the evaluation of PAOD with some tendency to overrate the grade of stenosis.
