What Is A Virtual Colonoscopy?
A virtual colonoscopy is a CT scan of your abdomen after the colon has been gently filled with air. The scan is then sent to a computer workstation where the data is analyzed. The exam takes only about 15 minutes to perform, eliminates any risk of colon perforation, and the patient does not need to be sedated.
In addition, this process allows the performing physician to see other abdominal organs, resulting in early diagnosis of kidney cancers, liver cancers, kidney stones, and other diseases.
While CT colonography is an evolving technology, recently published studies with modern multi-slice equipment such as that utilized at South Jersey Radiology Associates (SJRA) show detection rates (sensitivity) of 90-95% for polyps greater than 1 cm in size, in essence, as effective as traditional, invasive colonoscopies. Insurance coverage for a virtual colonoscopy varies by provider.
