摘要
目的研究肺间质病变的高分辨CT(HRCT)表现及鉴别诊断。方法采用HRCT法对88例临床病理证实的肺间质病变作影像分析。结果HRCT可清晰显示所有病例的肺间质病变征象,常表现为支气管血管束周围间质增厚(27例);肺小叶改变,其中包括小叶内间质异常(35例)、小叶间隔增厚(36例);毛玻璃影(38例);蜂窝征(41例);胸膜下间质改变(33例):出现界面影、胸膜下线、网织样变;受牵支气管扩大(28例)。结论HRCT对判断肺间质病变有影像诊断价值。
Objective To Study the appearances of high resolution CT(HRCT) images in diagnosing interstitial lung diseases. Methods Eighty-eight clinical pathologic confirmations cases of interstitial lung diseases were examed with HRCT. Results HRCT is clear to show the features of interstitial lung diseases, often displaying as follow:interstitium around bronchus and vascular bundle was thick (27 cases); little lobules of lung changed, including abnormal interstitial substance (35 cases),interlobular septum thickening(36 cases); the sign of frosted glass (38 cases) or beehive (41 cases); Interstitial changing under the pleural (33 cases):the appearance of interface, the line inferior membrane pleuralis, the sign of graticule; bronchiect in diseased region (28 cases). Conclusion HRCT is useful to judge the interstitial lung diseases.
