摘　　要：目的 :探讨肺部孤立结节内空泡征的HRCT表现及其对诊断早期肺癌的价值。方法 :对手术病理证实的肺内孤立结节 176例 (肺癌 12 9例 ,良性结节 4 7例 )的普通CT及HRCT扫描表现回顾性研究 ,分析了肺内孤立结节空泡征的HRCT表现。结果 :(1)在显示直径为≤ 2 .0cm结节空泡征HRCT优于普通CT。 (2 )空泡征在肺癌和良性结节出现率分别为 2 7.8%及 8.5 %。两者有显著差异 (P <0 .0 5 )。 (3)空泡征在直径≤ 2 .0cm的肺癌中出现率最高。结论 :空泡征是鉴别肺内孤立结节良、恶性的重要依据之一。Objective:To evaluate the high resolution CT(HRCT) findings of vacuole sign in solitary pulmonary nodule,and its value in the early diagnosis of lung cancer.Methods:the CT and HRCT findings of 129 cases lung cancer and 47 cases of benign pulmonary nodule that proved by pathlolgy were reviewed.Results:(1)HRCT was more sensitive than conventional CT depicting the vacuole sign in ≤2 0cm lesions. (2)the vacuole sign was observed 28.7% and 8.5% of malignant and benign nodule respectively.(3)the rate of vacuole sign is significant high in ≤2.0cm lung cancer.Conclusion:The vacuole sign is one of the most important sign in differential diagnosis between malignant and benign nodule,and has value in diagnosis lung cancer,especially in early stage.
