 Generally it is inferred that imaging of flat lesions using CTC is difficult. In this study we examined twenty-seven lesions of LST by CTC and colonoscopy. We found that CTC was useful for imaging lesions with tumor height greater than 2mm and tumor diameter exceeding 20mm. Surface colorectal cancers were imaged significantly more frequently than adenomas. Clinically, lesions that require treatment have a tendency to be imaged, and CTC will become more important in clinical settings with accumulation of knowledge and progress in the development of equipment and novel techniques.
