多层螺旋CT在肺动脉栓塞诊断中的应用

Application of multislice spiral CT in diagnosis of pulmonary embolism

目的:探讨多层螺旋CT(MSCT)在肺动脉栓塞诊断中的价值。方法:回顾性分析我院12例诊断为肺栓塞的患者,均用美国GE16排螺旋CT机进行双期扫描后,将获得数据传至工作站进行后处理,观察肺动脉栓塞的直接和间接征象及栓塞血管级别。结果:MSCT可清晰地显示肺栓塞直接和间接征象及栓塞血管分级。结论:MSCT扫描速度快,空间分辨率高并且强大的图像后处理功能,在肺栓塞的诊断中能提供非常精确的信息,有望成为肺栓塞诊断中的最佳手段之一。

Objective： To investigate the value in pulmonary embolism diagnosis using MDCT. Methods： The CT features of 12 cases with pulmonary embolism were analyzed retrospectively after CTPA exam handling in workstation. Direct and indirect sign of pulmonary embolism and pulmonary artery branchs of embolism were observed. Results： MSCT could clearly display direct and indirect sign of pulmonary embolism and pulmonary artery branchs of embolism. Conclusion： MSCT has some advantages： fast scaning, high space resolution, strong images post processing function and so on. It may be one of the optimal method in pulmonary embolism diagnosis.
