目的 探讨单纯标准摄取值 (SUV)及综合判断在肺内占位病变诊断中的价值。方法 行PET检查并经病理检查证实的肺部占位病变患者共 80例 ,对其PET显像结果进行分析。结果 单纯SUV诊断的准确性、灵敏度、特异性分别为 72 .5 % ,76.0 % ,65 .0 % ;综合判断的准确性、灵敏度、特异性分别为 88.8% ,90 .0 % ,84.6%。结论 依据SUV结合临床资料进行综合判断 ,可显著提高PET显像鉴别肺部良恶性病变的准确性。
Objective To investigate the value of simple standard intake (SUV) and comprehensive judgment in the diagnosis of space occupying lesions in the lung. Methods A total of 80 cases of lung space occupying lesion confirmed by PET examination and confirmed by pathology were analyzed and their PET imaging results were analyzed. Results The accuracy, sensitivity and specificity of simple SUV diagnosis were 72.5%, 76.0% and 65.0% respectively. The accuracy, sensitivity and specificity of comprehensive diagnosis were 88.8%, 90.0% and 84.6% respectively. Conclusion According to SUV combined with clinical data to make a comprehensive judgment, can significantly improve the accuracy of PET imaging to identify benign and malignant lung lesions.
