Fig. 2From: Role of PET/CT in the follow-up of postoperative and/or post-therapy cancer rectum: comparison with pelvic MRIa–f PET/CT study for the same patient in Fig. 1. a MIP, b–f sagittal, coronal and axial Fused PET-CT images revealed: Long segment of diffuse central low grade FDG uptake seen involving the rectum and anal canal (max. SUV ~ 4) (likely post therapeutic sequelae); however a focal eccentric area of slightly higher FDG uptake ((max. SUV ~ 5) is seen involving the lower rectum at 6–7 O’clock (worrisome about residual viable tumoral lesions), for close follow-upBack to article page
