This one and one-half day workshop has been designed to review current aspects of colon cancer and colon cancer screening. The format is hands-on training using workstations loaded with approx. 25-40 "endoscopically proven" data sets, chosen to include a mix of normals, abnormals and pitfalls. In addition to the hands-on experience, didactic lectures are included on patient prep, data acquisition, current screening techniques and how Virtual Colonoscopy fits in with overall patient management.
