目的:探讨夹层动脉瘤的多层螺旋CT扫描方法及三维重建技术。方法:对11例临床怀疑有胸、腹主动脉夹层动脉瘤患者均进行了多层螺旋CT血管造影胸腹联合扫描检查,将原始数据在工作站进行MR I、3D-CTA、M IP、SSD等后处理。结果:其中6例诊断有夹层动脉瘤,3例为胸主动脉夹层动脉瘤,3例为腹主动脉夹层动脉瘤。结论:通过多层螺旋CT血管造影结合影响后处理技术,可清晰显示夹层动脉瘤的起始和终结部位及破裂口所在位置。
Objective: To investigate the multi-slice spiral CT scan method and three-dimensional reconstruction of dissecting aneurysms. Methods: 11 cases of suspected thoracic and abdominal aortic dissecting aneurysms were examined by multi-slice spiral CT angiography combined with thoracoabdominal scanning, the raw data in the workstation MR I, 3D-CTA, M IP, SSD, etc. Post-processing. Results: 6 cases were diagnosed as dissecting aneurysms, 3 cases were thoracic aortic dissecting aneurysms and 3 cases were abdominal aortic dissecting aneurysms. CONCLUSIONS: The location of the beginning and the end of dissecting aneurysms and the location of rupture can be clearly shown by MSCT angiography combined with post-processing techniques.
