摘要
目的:探讨双源螺旋CT尿路造影技术的临床应用价值。方法:回顾性分析有临床症状并行双源CT尿路造影的病例86例,通过常规平扫、动脉期、静脉期、延迟期扫描将所获得的数据进行MPR、MIP、CPR及VR三维重建。然后对获得的影像进行分析。结果:所有病例均可成功重建出双肾、输尿管和膀胱的三维图像,能够通过旋转、放大等清晰显示全尿路及其局部细微结构、形态、走形及与周围组织的关系。结论:通过双源CT对全尿路的适当扫描,对采集的数据进行各种三维重建,能够大大地提高病灶的阳性率和诊断率。
Objective To evaluate the technology and application of dual-source CT urography. Methods 56 cases with clinical symptoms and dual-source CT urography were analyzed retrospectively through conventional plain scan, arterial phase scan, venous phase scan, which gained data were reconstructed 3D images of MPR, MIP, CPR and VR, and the images were analyzed. Results The 3D images of kidneys, ureters and bladder were reconstructed successfully, which showed clearly the detail of the entire urinary tract and the local fine structure, morphology, taking shape and the relationship with the surrounding tissue through rotating and zooming. Conclusion Through the dual-source CT to scan the entire urinary tract is suitable for a variety of data acquisition of three-dimensional reconstruction, which can greatly enhance the focal positive rate and diagnosis rate.
