Virtual colonoscopy provides clear, detailed images of polyps that are--mm or larger.
Virtual colonoscopy uses a CT scan and computer software to produce images of the colon and rectum.
In another study, virtual colonoscopy had advantages for follow-up of targeted populations.
Colonoscopy, virtual colonoscopy, and double contrast barium enema require the same bowel preparation.
Additionally, iCAD is developing CAD solutions for use with virtual colonoscopy to improve the detection of colonic polyps, iCAD's systems are based on sophisticated algorithms that analyze the data, automatically identifying and marking suspicious regions in the images.
The virtual colonoscopy (CT colonography, or CTC) could make life just a little bit easier when it comes to discussing colorectal cancer screening options with your patients.
Virtual colonoscopy, which uses X-rays and computers to diagnose colorectal cancer and bowel disease less invasively than traditional colonoscopy, has potential for people who may not be able to handle a traditional colonoscopy.
Several options exist for colon cancer screening: fecal occult blood tests (which checks for hidden blood in the stool), flexible sigmoidoscopy (which uses a short flexible scope to examine the lower portion of the colon and rectum), barium enema (an X-ray of the colon), virtual colonoscopy (a more specialized X-ray using CAT scan technology) and colonoscopy (which uses a long flexible scope to examine the entire colon).
Computed tomography (CT) colonography (virtual colonoscopy) is a promising new method for detecting colorectal polyps and cancers.
The computerized scans offer cost savings and can be less invasive, as in the case of virtual colonoscopy. Only a short probe is needed, making the exam much less intrusive and risky than the traditional colonoscopy.
In addition to being an effective screening tool for colorectal cancer, virtual colonoscopy also may detect heart attack risk in patients, according to a new study.
Virtual colonoscopy, a scanning procedure designed to spot cancer-related growths in the colon, may offer a side benefit: identifying heart attacks that are waiting to happen.
