This week a listener asked about virtual colonoscopy. Virtual colonoscopy uses Cat Scan and computer imaging to produce two- and three-dimensional images of the colon. Although the preparation is the same as traditional colonoscopy, the benefit is that no sedation is necessary, and the exam only takes about 10 minutes. According to Fox Chase radiologist Dr. Kristin Edwards, studies show that virtual colonoscopies are just as effective as traditional ones in detecting large polyps and colon cancers. Since colon cancer is a leading cause of death, and early detection is essential, colonoscopy is vitally important. At Fox Chase, our expertise in virtual colonoscopies provides an option for patients when traditional colonoscopies are incomplete.
