摘要
目的 探讨螺旋CT对肠系膜上动脉狭窄的诊断价值。方法 对经DSA或临床证实的5例肠系膜上动脉狭窄的病例进行回顾性分析其CT平扫及增强扫描图象特点,并结合容积再现(VR)、多平面重建(MPR)、最大密度投影(MIP),曲面重建的重建显示方式,观察肠系膜上动脉的形态。结果 5例病例轴位及重建图象均能很好显示肠系膜上动脉狭窄,与DSA或临床结果相符。结论 MSCT平扫及增强扫描及其后处理能快速准确地诊断肠系膜上动脉狭窄,具有重要的临床使用价值。
Objective To assess the diagnostic value of multi -slice CT (MSCT)in superior mesenteric artery stenosis. Methods 5 patients with superior mesenteric artery stenosis who were eomfirmed by clinical data or DSA underwent Plain CT scan and enhanced seanning,CT angiograms of superior mesenteric artery were produced using volume rendering technique ,multi -planar reconstruction ,maximal intensity projection and curved planar reconstruction. All the clinical data were retrospectively analyzed. Results Both axial scan and image reconstruction can well display the superior mesenteric artery stenosis and the results has a good agreement with the clinical data or DSA in 5 patients. Conclusion Plain CT scan and enhanced scanning can display the superior mesenterie artery stenosis quickly and accurately and have important value in clinical application.
