目的：探讨多层螺旋CT（MSCT）增强簿层扫描及图像后处理技术在肺隔离症(PS)的诊断价值。方法分析经临床手术病理、主动脉造影证实的21例肺隔离症患者的胸部多层螺旋CT平扫及CTA检查，并进行多平面重建(MPR)、最大密度投影法重建(MIP)、容积重建(VR)。结果21例病例均为单发，肺隔离症（PS）位于左肺下叶14例,右肺下叶7例；表现为肺野内团片、实性肿块者15例，囊样病灶者6例；21例孕杂的供血动脉均来自自体动脉,其中18例来自胸主动脉分支,3例来自腹主动脉。结论多层螺旋CT（MSCT）后处理技术能较准确、直观显示肺隔离症的供血动脉，可以取代有创DSA检查。“,”Objective To evaluate the multi-slice spiral CT (MSCT) reinforced thin layer scanning and image processing technique in the diagnosis of pulmonary sequestration (PS) value. Methods Analysis the clinical operation pathology, aortic angiography confirmed 21 cases of chest multi-slice spiral CT plain scan and CTA of pulmonary sequestration were examined, multi planar reconstruction (MPR), and the reconstruction of maximum intensity projection (MIP), volume rendering (VR). Results 21 cases were solitary, pulmonary sequestration (PS) located in the left lower lobe in 14 cases, right pulmonary lower lobe in 7 cases;for the performance of lung field of tanacu, solid mass in 15 cases, 6 cases of cystic lesion; artery in 21 cases of PS were derived from autologous artery, including 18 cases from aortic branch, 3 cases from the abdominal aorta. Conclusion Multi slice spiral CT (MSCT) after treatment technology can accurately, visual display of pulmonary sequestration artery, can replace invasive DSA examination.
