摘　　要：目的探讨十六层螺旋CT血管成像(MSCTA)在主动脉夹层中的诊断价值。方法回顾性分析13例经手术证实的主动脉夹层的MSCTA表现。图像采用软组织函数重建方法,重建层厚1.0mm,间隔0.7mm。图像后处理包括采用多平面重组(MPR)、最大密度投影法(MIP)和容积再现(VR)等技术。结果主动脉MSCTA能清晰显示夹层的范围、内膜片的形态、破口的位置、真假腔和附壁血栓以及与周围大血管的关系。结论主动脉MSCTA,具有快速、准确、简便的特点,在主动脉夹层动脉瘤的诊断中有重要价值,可作为影像学诊断主动脉夹层的首选。Abstract： Objective To discuss the diagnostic value of 16 - slice spiral CT angiography in dissecting aneurysm of aorta. Methods The findings of multi - slice spiral CT angiography （MSCTA） for 13 patients with aortic dissection verified by surgery were analyzed retrospectively. The imaging parameters were set as following： section thickness 1.0mm, standard reconstruction space 0.7mm. The volume data of all patients were reconstructed using 3D techniques including multi- planar reconstruction （MPR）, maximum intensity projection （MIP） and volume rendering （VR）. Results All the 13 cases could be displayed clearly by MSCTA with the range of the aortic dissection, intimal flap, the location of the rupture, true and false lumen, mural thrombus around the tumor and the relationship with peripheral big vessels. technique, which plays an important role Conclusion Aortic MSCTA is a in diagnosis of aortic dissecting and convenient, quick and accurate imaging should be the first choice for diagnosis of aortic aneurysm.
