Clinical Trial Summary

To evaluate the potential usefulness of 68Ga-FAPI positron emission tomography/computed tomography (PET/CT) for the diagnosis of primary and metastatic lesions in lung adenocarcinoma, compared with 18F-FDG PET/CT.


Clinical Trial Description

Participants with lung adenocarcinoma underwent contemporaneous 18F-FDG and 68Ga-FAPI PET/CT for an initial assessment. Tumor uptake was quantified by the maximum standard uptake value (SUVmax). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 18F-FDG and 68Ga-FAPI PET/CT were calculated and compared to evaluate the diagnostic efficacy. In addition, the investigators further investigate the performance of 68Ga-FAPI PET/CT for differentiating invasive adenocarcinoma from adenocarcinoma in situ (pre-invasive lesion) or minimally invasive adenocarcinoma in participants with solitary ground-glass opacity nodules. ;
