目的 研究支气管扩张黏液栓的影像诊断及鉴别诊断。方法 对 32例支气管扩张患者拍正侧位胸片及普通CT扫描 ,其中 15例行病变区高分辨率CT扫描。对病变局限于一个叶或段的 15例进行肺叶或肺段切除。结果 X线平片显示支气管扩张 15例 ,17例显示肺纹理柱状增粗 ,提示支气管黏液栓。 32例CT支气管黏液栓表现为棒状、分支状及结节状高密度影。CT值 - 18～ 32Hu ,普通CT与HRCT在显示黏液栓方面无差别。另外 14例病变肺叶合并肺气肿。结论 仅有黏液栓表现时X线平片易误诊 ,CT能准确显示黏液栓的形态、程度及普及的范围 ,是诊断支气管扩张黏液栓的最好方法。
Objective To study the imaging diagnosis and differential diagnosis of bronchiectasis mucus suppository. Methods Thirty-two patients with bronchiectasis underwent lateral radiography and plain CT scan, of which 15 were performed high-resolution CT scan. 15 cases of lesions limited to a leaf or segment of the lobectomy or segmentectomy. Results X-ray showed bronchiectasis in 15 cases, 17 cases showed pulmonary thickening of the columnar, suggesting bronchial mucus plug. 32 cases of bronchial mucosal CT showed sticky, branched and nodular high density. CT value - 18 ~ 32Hu, CT and HRCT showed no difference in mucus plug. Another 14 cases of lung disease with pulmonary emphysema. Conclusion Only the mucoid suppository is easy to misdiagnosis of X-ray films, CT can accurately show the morphology, extent and spread of mucus plug is the best way to diagnose bronchiectasis mucus plug.
