寻常型间质性肺炎的MSCT诊断

Diagnosis of multi-slice CT in usual interstitial pneumonia

目的探讨寻常型间质性肺炎(UIP)的MSCT影像学特征。方法收集经病理和临床实验性治疗证实的UIP患者16例,行胸部MSCT扫描。结果 UIP的主要MSCT表现:①磨玻璃样密度影;②肺小叶间隔增厚;③斑片状含气实变影;④支气管血管束异常,表现为边缘毛糙、光滑或有结节;⑤蜂窝肺;⑥胸膜下弧线影;⑦小叶内间质增厚(网格状阴影);⑧胸膜增厚。结论 MSCT诊断UIP具有较高的准确性,有重要的临床应用价值。

【Objective】 To investigate the MSCT radiological features of Usual interstitial pneumonia.【Methods】Sixteen patients with UIP were identified pathologically and in clinical trials of treatment.The chest MSCT scanning was performed in all patients.【Results】 The main findings were as follows： ①ground glass opacity;②thickened pulmonary lobular sepla;③patchy air-space consolidations;④Thickening of bruncbovascular bundles with coarse,blurred or smooth bundles,and nodular shape;⑤honeycomb lung;⑥Subpleural lines;⑦Thickening lobular interstition;⑧pleural thickening.【Conclusions】 UIP can be accurately diagnosed by using MSCT,and MSCT has important value in clinical application.
