目的应用18F - FDG PET/CT诊断孤立性肺结节(SPN)的良、恶性,以评价其临床价值.方法回顾性分析28例SPN患者的临床资料,根据确立的PET/CT诊断标准诊断SPN的良、恶性,以手术病理作为金标准.计算18F- FDG PET/CT诊断SPN的灵敏度、特异性、准确性、阳性预测值和阴性预测值.结果 18F- FDG PET/CT诊断正确25例,假阴性2倒,假阳性1例,其对SPN的诊断灵敏度、特异性、准确性、阳性预测值和阴性预测值分别为89.5％、88.9％、89.3％、94.4％和80.0％.结论综合分析PET/CT中18F - FDG代谢表现和CT征象,能准确诊断SPN的良、恶性.

Objective To diagnose benign or malignant solitary pulmonary nodules (SPNs) with 18F - FDG PET/CT and evaluate its clinical values.Methods Twenty - eight cases of SPNs were retrospectively reviewed.Benign or malignant SPNs were diagnosed according to the established criteria of PET/CT,and results of operational pathology were regarded as gold standard.Sensitivity,specificity,accuracy,positive predict values and negative predict values for SPNs diagnosed by 18F - FDG PET/CT were calculated respectively.Results Twenty-five cases were correctly diagnosed by 18F- FDG PET/CT,and three cases were misdiagnosed,including two false negative cases and one false positive case.Sensitivity,specificity,accuracy,positive predict values and negative predict values for SPNs diagnosed by 18F - FDG PET/CT were 89.5％,88.9％,89.3％,94.4％ and 80.0％,respectively.Conclusions Benign or malignant SPNs can be correctly diagnosed by synthetic analysis of 18F - FDG metabolism and CT features.
