Relevance of Incidental Colorectal FDG-PET/CT-Enhanced Lesions

Abstract

Incidental findings of focal colorectal FDG uptake should lead to further workup with colonoscopy. The SUVmax was not predictive for higher grade histologies. With an SUV of 5 the yield was high for colonic premalignant and malignant lesions. However, malignancy cannot be ruled out in focal lesions with an SUV of less than 5, and for individual patients a colonoscopy should not be ruled out.
