Abstract:
Virtual colonoscopy (VC), also known as CT colonography, continues to gain momentum worldwide as a safe and accurate alternative to traditional optical colonoscopy (OC) for colorectal cancer (CRC) screening. Within the US Army medical system, VC has experienced sustained growth since the program's inception in 2003. Integral to the success of this screening program has been dedicated radiologists and clinical support staff, collaboration with gastroenterology and an active training program for radiologists. Increasing patient and physician acceptance of the VC program along with radiologist education will ensure continued penetration of this valuable screening tool into the US Army medical system.
