Diagnostic value of MR angiography in aortic dissection
2011
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 Ⅰ24 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.
