摘要
目的 探讨磁共振成像在主动脉夹层诊断与评估方面的价值。方法 对 19例经磁共振成像自旋回波序列和梯度回波序列诊断为主动脉夹层的患者进行了研究 ,对比分析不同序列及不同体位在观察主动脉夹层内膜瓣、破口位置、分支血管受累情况及区分真腔和假腔方面的诊断价值。结果 17例显示了内膜瓣 ,其余 2例依靠真假腔内血流信号不一致做出诊断 ,13例显示了近端破口 ,其中I型 2例 ,Ⅱ型 2例 ,Ⅲ型 9例。结论 磁共振成像是诊断主动脉夹层首选的无创性检查方法 。
Aim To investigate the value of magnetic resonance imaging in the diagnosis and evaluation of aortic dissection. Methods 19 patients with aortic dissection diagnosed by using spin echo and gradient echo sequences of magnetic resonance were studied. We have discussed the diagnostic value of different sequences and positions of magnetic resonance for visualizing the intimate flap,the site of tear,origins of aortic branches and differentiating the true lumen from the false. Results Among these 19 patients with aortic dissection, 17 cases showed the intimate flap. 13 cases showed the entry tear and were classified into DeBakey typeⅠ, Ⅱ and Ⅲ in 2, 2 and 9. Conclusion Although magnetic resonance imaging has some limitations,it is the first choice for the diagnosis of aortic dissection,and is significant for the management of aortic dissection.
