| 目的 回顾分析95例直径≤2cm的肺孤立性小结节的HRCT表现,以评价HRCT在肺孤立性小结
节诊断上的价值。方法 95例直径≤2cm的孤立性小结节常规CT扫描后结节
处加扫3~5层HRCT。对不同病变结节的边缘、形态及内在特征进行对比分析。结果 HRCT显示结节边缘有切迹或分叶状,毛
刺影及偏心小针尖状钙化更倾向于肺癌诊断,无一种HRCT征象是小肺癌结节所特有的。结节
内发现脂肪是错构瘤的特征性表现,小结节内含液性密度提示是肺脓肿的可能。胸膜皱缩征
对鉴别肺癌或结核瘤无帮助。结论 HRCT对肺孤立性小结节的诊断和鉴别
诊断有重要的价值。 |

| Purpose To evaluate the value of HRCT in the diagnosis of smal
l solitary pulmonary nodules. Methods Ninety-five solitary pu
lmonary nodules with diameter ≤2cm were performed HRCT scan after common CT scan and were an
alyzed the edge,configuration or internal architecture by two radiologists. Results The lobulation,specula or partial needl-like calcification of SPN on HRCT were found commonly in lung cancer,but none of them was found only in lung canner; fat-density in SPN was the characteristic feature of
hamartoma,low-density was found usually in lung abscess,pleural indentation wa
s found in lung cancer and tuberculoma. Conclusion HRCT was a valuable method in diagnosis and distinguishing diagnosis of SPN. |
