1. To show the sequential morphological changes of various colorectal neoplastic lesions, based on the imaging findings obtained from follow-up surveillance CT colonography, conventional abdominal CT, barium enema and colonoscopy. 2. To familiarize the audience with the developmental process and characteristics of the lesions showing progressive behavior. 3. To understand key imaging findings of the lesions which should be detected effectively to reduce mortality.

1. Review of the developmental process (natural history) of colorectal neoplastic lesions. 2. Introduction of typical shapes and characteristics of clinically indolent lesions and progressive life-threatening lesions. 3. Case series using 2D- and 3D- images in a quiz case-study format, including adenoma, serrated adenoma, adenocarcinoma with or without submucosal invasion and advanced adenocarcinoma. 4. Answer for all questions.
