摘　　要：目的探讨Bone Removal去骨多层螺旋CT血管成像技术(MSCTA)对诊断内脏动脉瘤的临床价值。方法回顾性选取1486例行腹部常规多期增强扫描患者的动脉期薄层图像,利用Bone Removal软件进行动脉去骨血管成像,筛选与诊断内脏动脉瘤;并与常规轴位图像已作出的诊断相比较,部分患者同时与DSA结果进行对照。结果 Bone Removal去骨MSCTA技术共发现内脏动脉瘤26枚,其中与动脉期常规轴位图相比新发现内脏动脉瘤18枚,行DSA检查的11枚内脏动脉瘤与去骨MSCTA相符。结论利用Bone Removal软件对MSCT常规腹部增强动脉期薄层图像,进行快速去骨血管成像,能显著降低内脏动脉瘤漏诊,值得临床推广。Objective To investigate the clinical utility of multi-slice spiral CT angiography（MSCTA） with bone removal technique for diagnosing visceral artery aneurysms.Methods The arterial phase thin-slice images of 1486 patients who underwent routine MSCT enhanced scans of the abdomen were retrospectively selected and treated by bone removal angiography software to screen and to diagnose vis ceral artery aneurysms.The mumbers of aneurysms visualized by bone removal angiography technique were compared with those visualized by routine axial view images,while those in partial patients were compared with DSA.Results Twenty-six visceral artery aneurysms in the group patients were detected by bone removal angiography,of them,18 were invisible on routine axial view images.Eleven aneurysms found in bone removal angiography were showed in DSA as well.Conclusion Utilizing Bone Removal software for arterial phase thin-slice images of routine enhancement MSCT in abdomen can significantly reduce the leak-diagnosis of visceral artery aneurysms so that it is worth to popularize clinically.
