肺部弥漫性病变的影像学分析(附80例报告)

目的 探讨肺部弥漫性病变的X线诊断。方法 回顾分析80例肺部弥漫性病变的X线表现。结果 根据X线征象分析为(1)主质病变，包括腺泡结节，小片及大片阴影，支气管充气征；(2)间质病变，包括间质结节，网状及网状结节阴影，支气管血管束的增粗；(3)主间质病变，包括毛玻璃影，多发肿块及蜂窝状改变。同时对肺弥漫性病变做进一步探讨。结论 常规胸片目前仍是诊断肺弥漫性病变的首选方法，而CT则是重要的辅助手段。

Imaging analysis of diffuse lung diseases: a report of 80 cases

Objective To investigate the X- ray diagnosis and imaging features of diffuse lung diseases(DLD).Methods Thoracic X- ray findings of 80 patients with DLD were analyzed retrospectively.Results According to X- ray findings,the lesions of DLD could be divided into the following three kinds of types:(1)parenchymal lesions such as acinic- form nodules,small or large patchy shadows and air bronchogram;(2)interstitial lesions such as interstitial nodules,reticular shadows or reticular- nodular shadows,and thickened of bronchial vessel bundles;(3)parenchymal and interstitial mixed lisions such as ground- glass shadows,multiple masses and honeycomb changes.Conclusion At present,conventional X- ray thoracic film remains a main method for diagnosing DLD whereas CT is its important supplementary means.
