PRIMARY COLORECTAL CANCERS DETECTED WITH PET

Positron emission tomography (PET) using F-18-fluorodeoxyglucose can s ensitively detect cancers of increased glucose metabolism. We describe three asymptomatic individuals who were found to have colorectal canc er and underwent potentially curative surgery. On the PET images, lesi ons were easily discernible. Our experience and the experience of othe rs suggest that primary colorectal cancer can be detected with PET in a resectable stage, Our three cases are presented and the potential ut ility of PET is discussed.
