肺隔离症的CT诊断

CT Diagnosis of Lung Sequestration

目的：分析肺隔离症的ＣＴ表现，以提高诊断正确率。材料和方法：对１３例肺隔离症患者采用胸部ＣＴ扫描，病灶薄层增强扫描，并经手术病理证实。结果：１３例患者的病灶均位于两肺下法后基底段。在ＣＴ片上１３例中有１０例表现有异常供血血管。结论：ＣＴ在诊断肺隔症上具有较高的价值。

urpose: To analyze CT appearances of lung sequestration so as to enhance diagnotic correctivity of the disease. Materials and methods: All thirteen cases with lung sequestration proved by surgery and pathology were perforned with chest computed tomography. Results: All cases were located in the posterior segment of lower lobes of both lungs. On CT images, the disease appeared some characteristic findings. Abnormol suppling blood vessels of the lesion could be seen on CT in 10 of 13 cases. Conclusions: Computed tomography is of high value in the diagnosis of lung sequestration, especially in showing suppling vessels.
