Virtual colonoscopy -- promising, but not ready for widespread use

Article Abstract:

Virtual colonoscopy is a promising diagnostic tool but some problems remain to be resolved. This technique involves using helical CT imaging to create two-dimensional images of the colon, which are then converted into three-dimensional images. It is meant to replace colonoscopy, which involves inserting an endoscope up the rectum, an expensive and often painful procedure. Faster scanners are needed that can detect small intestinal polyps. Software must be improved to shorten the time it takes to create the final image. If these problems can be solved, the technique could be a noninvasive way of detecting colorectal cancer.

A comparison of virtual and conventional colonoscopy for the detection of colorectal polyps

Article Abstract:

Virtual colonoscopy may be an effective and low-cost method of diagnosing colorectal cancer. During this procedure, helical computed tomography (CT) is used to create two-dimensional images which are then converted into three-dimensional images. The traditional way of examining the colon is to stick an endoscope up the rectum, which can be uncomfortable for the patient and expensive. In a study of 100 patients who received both procedures, virtual colonoscopy detected all the cancers and 90% of the adenomatous polyps larger than 6 millimeters. There were no false-positive findings of cancer.

Magnetic resonance cholangiopancreatography

Article Abstract:

Magnetic resonance cholangiopancreatography (MRCP) may soon replace endoscopic retrograde cholangiopancreatography (ERCP). Both are techniques for imaging the pancreas and biliary tract. However, ERCP involves exposing the patient to radiation. MRCP does not involve radiation and is therefore safer for the patient. It is based on magnetic resonance imaging (MRI) which takes advantage of the natural magnetic properties of body fluids and organs. It also does not involve injecting the patient with dyes. It is also cheaper than ERCP.
