摘　　要：目的：研究肺癌增强ＭＲＩ表现的病理基础，探讨其在肺部诊断中的作用。材料与方法：４７例原发性支气管肺癌，１０例结核球及５例其他良性病灶行平扫和增强ＭＲＩ检查，分析其增强表现并与病理对照。结果：所有肺癌在静脉注入Ｇｄ－ＤＴＰＡ后均有强化，表现为３种形式：均匀型、不均匀型和厚壁空洞型，结核球多数表现为薄壁环形增强，各种增强形式有不同的病理基础。结论：肺癌的增强形式与结核球不同。Objective: To evaluate enhancement characteristics of MR images and pathologic basis for making diagnosis and differential diagnosis of bronchogenic carcinoma.Materials and Methods: Pre and post enhanced magnetic rasonance imaging (MRI) of bronchogenic carcinoma (n=47), tuberculoma (n=10) and other benign lesions (n=5) were analyzed and compared with pathologic findings. Results: All bronchogenic carcinoma yield enhanced images after intravenous Gd DTPA appearing in one of 3 patterns, namely: homogeneous type, unevenly mottled type and thick wall cavity type; tuberculoma, however, generally manifest thin rim ring like enhancement and various enhancement patterns stem from different pathologic basis.Conclusion: The enhanced patterns of bronchogenic carcinoma differ from that of tuberculoma, thus beneficial to differential diagnosis.
