摘　　要：【目的】观察多层螺旋CT肺部常规增强和CTPA在肺动脉栓塞诊断中的应用价值。[方法】搜集2009年3月至2010年2月常规增强CT扫描发现而临床未拟诊肺栓塞病例13例，对原始数据采用MPR技术常规三雏重建；两天内进行肺血管CT血管成像（CTA），对原始数据采用最大密度投影（MIP）、容积再现（VRT）及多平面重建（MPR）技术对肺动脉进行三维重建。【结果】常规增强CT发现13例肺栓塞，栓塞动脉107支；CTPA确诊9例，栓塞动脉139支。【结论】CTpA相对常规增强CT灵敏性更高，但后者仍有较高临床价值，CTPA确诊并非必需。[Objective]To observe the clinical value of conventional enhancement of multi-slice spiral CT （MSCT） vs CTPA for the diagnosis of pulmonary embolism. [Methods]Thirty patients unsuspected of pulmonary embolism who were found by conventional enhanced-CT from March 2009 to January 2010 were collected. The conventional 3D-reconstruction was performed for the original data by using MPR technology. CTA of pulmonary vessel was performed in 2 days. MIP, VRT and MPR technology were used for the 3D-reconstruction of the original data of lung arteries. [Results] Thirteen cases of pulmonary embolism and 107 embolism arteries were found by conventional enhanced-CT. Nine cases of pulmonary embolism and 107 embolism arteries were confirmed by CTPA. [Conclusion] CTPA is more sensitive than conventional enhanced-CT, but the latter still has high clinical value. Therefore, CTPA is not so necessary.
