A Safe, Non-Invasive Procedure For Colon Cancer Detection
At Winchester Imaging, we utilize state-of-the-art helical CT scanning to rapidly scan the colon with x-rays, creating detailed 2D and 3D images. Virtual colonoscopy (colonoscopia virtual) is a non-invasive alternative to conventional colonoscopy.
Unlike traditional colonoscopy, which requires the introduction of a long tube into the rectum, virtual colonoscopy uses CT imaging to provide a comprehensive view of the colon.
How Does a Virtual Colonoscopy Work?
A virtual colonoscopy, or CT colonography, involves a quick and painless CT scan. The procedure typically takes about 15 minutes. During the scan, the patient lies on a table while the CT scanner takes detailed images of the colon. These images help detect polyps, cancer, and other abnormalities.
Who Should Have a Virtual Colonoscopy?
According to guidelines endorsed by the American Cancer Society and other national groups, colorectal cancer screening is recommended for individuals beginning at age 50. For those at high risk, screening should start at age 40. High-risk individuals include those with a family history of colorectal cancer, a personal history of inflammatory bowel disease, or other risk factors.
Advantages of Virtual Colonoscopy
Did you know that heart disease is the number one killer of women? American women are 5 times more likely to die of heart disease than breast cancer. Heart attack symptoms are different in women than men, often going unnoticed. Early detection with Cardiac Calcium Scoring can be life-saving.
