Diagnostic Value of the Rare CT Features in Pulmonary Nodule
Journal of Practical Radiology(2007)
摘要
Objective To study the rare CT features in pulmonary nodules,so that to elevate the diagnosis of peripheral lung carcinoma. Methods The occurrence ratio of rare CT features(including multi-cyst lucency, undefined patchy opacity between the tumor and the pleura and ground-glass opacity) were analyzed in 139 peripheral lung carcinomas and 47 other types of pulmonary nodules retrospectively. All cases were confirmed by surgical operation-pathology or clinic. Results The ratio of multi-cyst lucency and undefined patchy opacity between the tumor and the pleura were different between peripheral lung carcinoma and other pulmonary nodules,which in the later was higher than that in the former (P0.05). There was no difference of the occurrence ratio of ground-glass opacity between peripheral lung carcinoma and other pulmonary nodules.The occurrence ratio of ground-glass opacity in bronchioalveolar carcinoma(BAC) was higher than that in other types peripheral carcinoma (P0.001).Conclusion The multi-cyst lucency and undefined patchy opacity between the tumor and the pleura in pulmonary nodules predict peripheral lung carcinoma. The ground-glass opacity in peripheral lung carcinoma predicts BAC.
