[Abstract] Objective: To evaluate the value of magnetic resonance angiography (MRA) in diagnosing aortic dissection.Materials and Methods: We retrospectively analyzed MRA findings of 73 aortic dissection (AD) patients. Express and RF-FAST were used in the MR examination. The results were compared with the findings of surgery or DSA.Results: Seventy-three AD patients including DeBakey type Ⅰ 24 cases, DeBakey type Ⅱ 6 cases, DeBakey type Ⅲ 43 cases. Both the sensitivity and the specificity of the presence and the differentiation of aortic dissection were 100%. The sensitivity of the localization of intimal tears was 94.74%, but the specificity was 100%. The sensitivity of the involvement of arch branches was 91.49%, but the specificity was 92.31%.Conclusion: The aortic dissection can be diagnosed by MRA accurately and non-invasive. MRA can provide more useful information to clinical treatment.
