F-18 FDG PET/CT scan. Transaxial-, coronal-, and sagittal-section images of PET alone, CT alone and PET/CT fused images of the lungs show a discrete focus of increased uptake in the right lung middle lobe, without any structural abnormality on CT

F-18 FDG PET/CT study. F-18 FDG PET/CT images demonstrated an area of increased FDG uptake in the right lung middle lobe parenchyma, without any structural abnormality on CT [Figure 1].
A control F-18 FDG PET/CT scan performed after 4 days of the first PET/CT. Transaxial-, coronal-, and sagittal-section images of PET alone, CT alone and PET/CT fused images of the lungs revealed complete resolution of the previously noted FDG avid focus. No other abnormalities were noted

A repeat F-18 FDG PET/CT scan was performed after a brief interval of 4 days of the first study did not reveal any abnormality; the previously noted intense focus of FDG avidity having been completely resolved [Figure 2]; the latter suggesting the benign nature of the lung abnormality.
