摘　　要：目的:为了探讨腹主动脉螺旋CT三维重建的临床应用价值。材料与方法:使用TOSHIBAXPRESS/SX螺旋CT扫描机;以每秒5mm的进床速度,3mm的X线束厚度进行螺旋扫描;重建图像间隙为1.7mm;再用SUN SPARC STATION20工作站硬件,TOSHIBA XTENSION 2.01版本工作站软件,对10例患者的腹主动脉螺旋CT扫描数据进行三维重建。结果:10例中,有两例夹层动脉瘤,7例腹主动脉瘤,1例髂总动脉假性动脉瘤。腹主动脉CT扫描三维重建能显示腹主动脉全貌,动脉壁钙化及动脉瘤的形态、大小、位置、蒂部和血栓情况。结论:螺旋CT扫描获得的容积数据可以重建高质量的腹主动脉三维图像。能为临床医生提供腹主动脉直观的立体图像。便于临床医生制定手术方案。Purpose: To discuss the clinical application of three-dimensional (3D) reconstruction in abdominal aorta. Materials and methods: Helical scan in collimation of 3mm. Pitch = 5:3, 1. 7mm of reconstruction interval, and 3D reconstruction of abdominal aorta in 10 cases were performed with TOSHIBA XPRESS/SX CT scanner, SUN SPARC STA-TION20 workstation and TOSHIBA Xtension 2.01 software. Results: In the 10 cases, 2 were aorta dissection, 7 were abdominal aorta aneurysms and 1 was a psuedoaneurysm in common illiac artery. 3D reconstruction demonstrate not only the whole contour and calcification of the abdominal aorta, but also the shape, size, position, pedical and thrombus of the aneurysm. Conclusion: Helical CT can result in good quality image. 3D image helps the pre-operative diagnosis and surgical planning in the lesions of the abdominal aorta.
