目的：探讨校正标准摄取值(standard uptake value,SUV)在周围型孤立性肺病变诊断中的应用及校正 SUV 与病变体积之间的关系。方法回顾分析69例周围型孤立性肺病变的 PET 及 CT 征象,分别用标准方法和校正方法测量病灶的 SUV 及病灶体积,并分析二者之间的相关性。结果 PET/CT 及校正 SUV+CT 的诊断准确率分别为88.7%、98.5%,二者差异有统计学意义。病变 SUV 最大值(SUVmax)、校正 SUV 与体积呈正相关(r 1=0.536,P <0.001；r 2=0.637,P <0.001)。结论 PET/CT 对周围型孤立性肺病变的诊断具有很高价值,校正 SUV 能提高诊断准确率。病灶 SUV 与体积呈正相关。

Objective To evaluate the use of corrected standard uptake value(SUV)in patient with peripheral solitary pulmonary lesion and the relationship between corrected SUV and the lesion's size.Methods This retrospective study included 69 patients with peripheral solitary pulmonary lesions seen on PET and CT scans whose diagnoses were confirmed by pathology.Each lesion’s FDG uptake was quantified by using two methods:the SUV and the corrected SUV.The lesion’s size was recorded on CT.Results The diagnostic accuracy was 88.7% and 98.5% for PET/CT and combining corrected SUV with CT respectively.There was a positive correlation between SUV,corrected SUV and the size of lesions(r 1 =0.536,P <0.001;r 2 =0.637,P <0.001).Conclusion Measur-ing corrected SUV appears to improve the accuracy of FDG PET/CT for characterization of peripheral solitary pulmonary lesions . The volume of lesion may potentially affect the value of SUV.
