| 摘 要： | 报道32例肺癌脑转移的MR表现，病灶以大脑多发为主，伴有不同程度的灶周水肿，鳞癌易发生囊变，腺癌易卒中，T2wI图像上出血周围的低信号环不规则。增强扫描，发现平扫不能显示的病灶。由此可见MRI对肺癌脑转移的影像诊断具有重要价值。

| Abstract: | MR appearance of brain metastases from 33 cases of lung carcinoma was reported. The lesions were mainly localized in the cerebrum associated with edema in varying degrees. Squamous cell carcinoma had a tendency to cystic degeneration and adenocarcinoma to bleeding. The low signal rings around the bleeding locus were irregular in T2WI imaging. Enhanced MR could find the lesions that noncontrast-enhanced MR could not. From the above, it was concluded that MRI had an important value in the imaging diagnosis of brain metastases from lung carcinoma. |
