目的:探讨64排螺旋CT血管成像诊断主动脉夹层的价值。方法:主动脉夹层患者23例,均行64排螺旋CT血管成像检查,采用容积重建、多平面重建及曲面重建等方法进行三维重建。结果:DeBakeyⅠ型8例(34.8%),Ⅱ型3例(13.0%),Ⅲ型12例(52.2%)。主动脉重要分支受累5例(21.7%),均在三维重建中有特征表现。结论:64排螺旋CT血管成像是诊断主动脉夹层准确、快捷、有效地检查方法。
Objective: To explore the value of 64-slice spiral CT angiography in the diagnosis of aortic dissection. Methods: Twenty-three patients with aortic dissection were examined by 64-slice spiral CT angiography. Volume reconstruction, multiplanar reconstruction and curved surface reconstruction were used to perform 3D reconstruction. Results: There were 8 cases (34.8%) of DeBakey type I, 3 cases (13.0%) of type Ⅱ and 12 cases (52.2%) of type Ⅲ. Five cases (21.7%) of major aorta involvement were involved in the three-dimensional reconstruction. Conclusion: 64-slice spiral CT angiography is an accurate, rapid and effective method for the diagnosis of aortic dissection.
