Diana Mignognotti, a researcher at the University of California, Davis, warns that unless absolutely necessary, people should minimize the use of computed tomography (CT) scans, especially in children. Unnecessary CT scans have been empirically shown to significantly increase the risk of cancer in children.
Researchers point out that although CT scans involve radiation exposure, they remain a valuable diagnostic tool when necessary. However, the health risks associated with overuse should not be underestimated.
CT scans can also be used for colorectal cancer screening, but many physicians recommend opting for colonoscopy whenever possible. Yet, many people hesitate at the mention of a colonoscopy. Besides medical history, colorectal cancer diagnosis can utilize several screening tools, including digital rectal exams, rigid sigmoidoscopy, colonoscopy, and barium enema X-rays. However, these methods have limitations such as restricted examination scope and discomfort during the procedure, leading some to miss early detection and treatment opportunities.
Three-dimensional CT scanners can use virtual reality computer post-processing to produce dynamic images similar to real colonoscopy, simulating the effects of an endoscopic examination while also scanning organs outside the intestines.
Doctors note that 3D CT colonography is less invasive and provides full three-dimensional imaging of the colon. Some physicians believe it could serve as a screening tool for detecting colorectal cancer and polyps. However, patients should consider whether it is suitable for them before undergoing the procedure, as it still involves radiation exposure.
