Fig. 2
Colorectal cancer (arrow) as an incidental finding in the PET/CT restaging of oesophageal cancer with new lymph node and hepatic metastases. 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). Note that the 18F-FDG-filled bladder can obscure carcinomas on the coronal maximum intensity projection (MIP) (a). Rotating MIPs or scrolling through axial PET slices (b) is mandatory to detect such carcinomas. The colorectal cancer, here with an SUVmax of 9.7, is clearly depicted on the axial PET images (b) in contrast to CT (c)
