Total-body PET images of different types of cancers. a Total-body PET images of a 58-year-old man with infiltrating adenocarcinoma of the lung confirmed by surgery. The FDG-avid lesion in the upper lobe of the right lung is identified in MIP and axial images with different reconstruction times [39]. The times in the panel represent reconstruction duration. b Coronal view of the estimated time delay td map and Ki parametric images with and without time delay correction (TDC) for a patient with liver cancer. Arrows point to the liver cancer [54]. To better illustrate the lesions in the liver, the authors only demonstrate the upper part of the total-body PET images. c MIP maps with different reconstruction times of a 58-year-old male with adenocarcinoma of the splenic flexure of the colon diagnosed by pathological examination. The corresponding axial images show a low-grade intraepithelial neoplasia lesion in the descending colon [40]. The times in the panel represent reconstruction duration. d Total-body dynamic FDG PET images of a patient with metastatic renal cancer. The MIP images demonstrate higher renal FDG uptake in the late phase than that in the early phase [54]. The times in the panel represent scan time
