摘　　要：目的探讨MSCT血管造影及其后处理技术在叶内型肺隔离症中的诊断价值。方法回顾分析13例经手术和病理证实的叶内型肺隔离症患者的胸部CT平扫及增强扫描资料,对异常供血血管进行后处理重建,并与手术资料结果对比。结果 4例位于右下叶后基底段,另外9例病灶位于左下肺,其中7例位于左下叶后基底段;1例表现为含气的单房囊状影,8例表现为含气或和含液的多房囊状影,囊壁薄,增强后未见强化,4例表现为类圆形肿块,增强后有中等强化;血管重建均可显示病灶内供血的异常血管(其中3例来自腹主动脉上段,另外10例来自胸主动脉下段),并能清楚显示其起源、分支及行程,血管显示情况与手术一致。结论MSCT血管成像及其后处理技术能清晰显示病灶内异常的供血动脉,对叶内型肺隔离症的诊断具有重要的临床应用价值,可以取代血管造影。Objective To assess the value of MSCT and post-processing techniques in diagnosis of the intra-lobar pulmonary sequestration. Methods MSCT findings were analyzed retrospectively in thirteen patients with surgical and pathology conformed intra-lobar pulmonary sequestration, all patients underwent CT plain scan and contrast enhanced ,the vessels related to the lesions were recon by post-processing techniques ,then compared with the surgical results. Results four cases were located at the posterior basal segment in the right lower lobe. and the the rest of nine cases lesions were found in the basal segment of the left lower lobe, include seven cases were located at the posterior basal segment of the left lower lobe; One case was showed as single loculated cyst contains of air. and eight cases present as multi-loculated cyst contains of air with/fluid or in without contrast enhancement of cyst wall, four cases presented as round like mass with moderate enhancement. Angiography post-processing technique displayed abnormal supplying vessels in all patients（ten cases from descending aorta and three cases from abdominal aorta）and displayed the courser、origin、and branches of lesions clearly,which was consistent with surgery. Conclusion MSCT angiography with post-processing reconstruction techniques can depict supplying artery clearly of intra-lobar pulmonary sequestration and shows great value in the diagnosis of intra-lobar pulmonary sequestration,the conventional angiography technique might be replaced.
