目的：探讨孤立性肺小结节高分辨率CT诊断及临床治疗方法的相关性。方法回顾性分析2011年1月-2013年8月我院50例孤立性肺小结节患者的64排螺旋CT诊断结果及临床治疗情况。结果对于直径为≤1 cm、1 cm~2 cm及2 cm~3 cm的结节64排螺旋CT诊断敏感性分别为90.01%，97.35%及100%；特异性分别为50.25%，70.45%及80%。其中≤1cm的结节恶性率为35.1%，1 cm~2 cm结节恶性率为52.3%，2 cm~3 cm结节恶性率为76.5%。孤立性肺小结节的CT诊断及治疗因其大小及性质而存在明显差异。结论≤2 cm的孤立性肺小结节CT不能明确为良性时应行胸腔镜手术切除，2 cm~3 cm的肺孤立性小结节可先行穿刺活检明确病灶性质，恶性结节则行胸腔镜手术切除。

Objective To summarize the correlation of the solitary pulmonary nodule between the high resolution CT diagnosis and clinical treatment. Methods A retrospective study about 50 cases small solitary pulmonary nodules in 64 slice spiral CT diagnosis and clinical data. Results For diameter≤1 cm,1 cm~2 cm and 2 cm~3 cm nodules in 64 slice spiral CT diagnostic sensitivity was 90.01%, 97.35%and 100%;specificity were 50.25%, 70.45%and 80%. The nodule of diameter≤1cm malignant rate was 35.1%, 1 cm~2 cm nodules malignant rate was 52.3%by surgical removal of the pathological diagnosis, 2 cm~3 cm nodule malignant rate was 76.5%with biopsy in the diagnosis of specificity of 97.37%. The CT diagnosis of pulmonary nodules had obvious difference in its size and properties. Conclusion ≤2 cm nodules should be underwent thoracoscope surgery, 2 cm~3 cm nodules should first clear nature of the lesion biopsy and then malignant nodules should resect by thoracoscope surgery .
