Colorectal cancer (arrow) in the initial staging. Maximum intensity projection (MIP) of PET captured in the coronal projection of the 360°-rotation (a), axial slices of PET (b), CT (c) and PET/CT (d) and colonoscopy (e). As in Fig. 2, rotating the maximum intensity projection (MIP) or scrolling through axial PET slices (b) is mandatory to detect carcinomas behind the urinary bladder. PET clearly depicts the colorectal cancer, here with an SUVmax of 6.1
