摘要
探讨磁共振对肺结核的诊断价值。方法回顾分析５５例成人型肺结核磁共振和Ｘ线片表现。结果磁共振和胸片在反映肺结核浸润性、增殖性病理变化和空洞、结核瘤、干酪性肺炎病变类型方面无明显差别。浸润性、增殖性病灶及干酪性肺炎Ｔ１、Ｔ２加权像均呈中等信号，空洞呈低信号，结核瘤Ｔ２加权像多呈不均信号。
Objective To study the role of MRI in diagnosis of adult pulmonary tuberculos is.Methods MRI and X ray appearances of 55 adult pulmonary tuberculosis cases were reviewed.ResultsNo obvious difference was found between the images of MRI and chest radiography which reflect infil trative and proliferative pathologic changes of pulmonary tuberculosis(including cavity,tuberculoma and caserous pneumonitis).Infiltrative,proliferative lesions and caserous pneumonitis showed middle signal on the T 1 and T 2 weighted images.Cavity showed low signal.Tuberculoma showed generally hyteroge nous signal on the T 2 weighted images.Conclusion It is unnecessary to use MRI as aroutine tool for diagnosis of pulmonary tuberculosis.
