| 摘要: |
| ［目的］ 探讨细支气管肺泡癌的CT诊断要点。［方法］回顾性分析了经手术及病理证实的20例细支气管肺泡癌的CT扫描资料，并与24例周围型肺癌进行了对照分析。［结果］肺泡癌结节肿块病灶中的空泡征或细支气管气像的阳性率为64.71%(11/17)，其他周围型肺癌的阳性率为16.67%(4/24)，二者具有显著差异。叶段实变型肺泡癌主要表现为“枯枝状”支气管气像（3/3）和蜂窝状低密度区(2/3)。［结论］空泡征或细支气管气像、枯枝状支气管气像及蜂窝状低密度区是CT诊断细支气管肺泡癌的几个特征性征象。 |

| Abstract: |
| ［Objective］To study the CT diagnostic characteristics of bronchioloalveolar carcinoma.［Methods］The features of pathologically verified bronchioloalveolar carcinoma in 20 patients were retrospectively analyzed and compared with the other typical lung cancer.［Results］There was notable discrepancy on vacuole sign or the air brochiologram between bronchioloalveolar carcinoma and the other typical lung cancer. ［Conclusions］The some characteristic CT features included: vacuole sign or the air brochiologram, the withered tree air brochiologram and honeycomb shadows. |
