A case of colon cancer detected by carbon-11 choline positron emission tomography/computed tomography: an initial report.

[C-11] choline positron emission tomography ([C-11] choline PET) has been expected to be one of the new PET modalities similar to [F-18] fuluorodeoxyglucose positron emission tomography (FDG-PET), which has spread worldwide as a gold standard of PET oncologic imaging. However, there has been no report on [C-11] choline PET used for detection of colorectal cancer, which is one of major targets of oncologic FDG-PET. We initiated the research to investigate the detectability of [C-11] choline PET for various tumors including colorectal cancer. This is the first report of a patient who underwent surgical resection for advanced colon cancer depicted by [C-11] choline positron emission tomography/computed tomography.
