Figure 1
Rectal carcinoma depicted on PET-CT. (a) There is circumferential rectal thickening (arrow) on contrast-enhanced CT. (b) There is avid FDG radiotracer uptake (arrow) on axial FDG-PET. (c) Increased FDG uptake on FDG-PET correlates with thickening (arrow) due to rectal carcinoma seen on CT.
