摘　　要：目的探讨双源CT扫描血管成像对主动脉病变的诊断价值。方法对临床可疑主动脉病变的90例患者采用双源CT血管造影（CTA）检查，并对原始数据采用多平面重建（MPR）、曲面重建（CPR）、最大密度投影（MIP）和容积再现（VR）后处理技术进行重建。结果90例患者中共检出主动脉夹层27例，主动脉瘤14例，大动脉炎3例，主动脉粥样硬化15例，主动脉壁溃疡5例，主动脉壁内血n,5例，主动脉缩窄1例，主动脉变异1例，门静脉海绵样变性1例，布加氏综合征l例，肠系膜上动脉血栓2例，门静脉血栓1例，左肾动脉瘤1例，脾动脉瘤1例，肺动脉血栓4例，肾癌1例，正常7例。所有图像质量优良，有效射线剂量平均约3．14mSv。结论双源CT扫描对主动脉病变的诊断具有重要意义，并能降低辐射剂量。Objective To explore the value of the dual-source CT angiography （DSCT） in diagnosis of aortic disease. Methods 90 patients were suspected aortic disease with CTA, raw data were dealt ,with multiplanar reformation （MPR）, curved planar reformation （CPR）, maximum intensity projection （MIP） and volume rendering （VR）. Results The aortic disease in 90 cases included aortic dissection 27 cases, aortic aneurysm 14 cases, takayasu arteritis 3 cases, atherosclerotic 15 cases, aortic ulcer 5 cases, aortic intramural hematoma 5 cases, aortic coarctation 1 case, aortic variations 1 case, portal spongy degeneration 1 case, Budd-Chiari Syndrome 1 case, superior mesenteric arterial thrombosis 2 cases, portal thrombosis 1 case, left renal artery aneurysms 1 case, splenic artery aneurysms 1 case, pulmonary embolism 4 cases, renal cancer 1 case, normal aortic 7 cases. All the image quality is excellent, and the average effective radiation dose was 3.14 mSv. Conclusion Dual-source CT angiography is significant in diagnosing aortic disease, and can reduce radiation dose.
