主动脉夹层的MRI诊断

Magnetic Resonance Imaging in Aortic Dissection

目的：评价ＭＲＩ对主动脉夹层的诊断价值及优势。方法：对２０ 例主动脉夹层进行了ＭＲＩ检查，运用常规自旋回波（ＳＥ）技术及电影（ｃｉｎｅ）技术。结果：运用ＭＲＩＳＥ及ｃｉｎｅ ＭＲＩ，能够清楚地显示主动脉夹层的破裂口，撕裂的内膜片及真、假腔。结论：ＭＲＩ是诊断主动脉夹层的最佳影像诊断方法。

Objective: To evaluate the value of MRI in diagnosing aortic dissections. Methods: Twenty patients underwent spin echo (SE) MRI and cine MRI examinations. Results: All the cases showed the entry tears, intimal flap and double lumen. Conclusion: MRI is the optimal imaging techniques in diagnosing aortic dissections.
