Bowel test more patient-friendly

The system gives virtual images

A new technique for detecting cancer of the colon is to be tried out on several thousand NHS patients.

They will be given a virtual body scan, instead of the internal examination which is usually necessary to detect any growths.

The scanner gathers a series of images and the data is processed into an easy-to-use form.

Colon cancer kills 16,000 people in the UK every year. But if caught early 90% of cases can be cured.

However, the current diagnostic technique, which involves inserting a device with a mini-camera into the colon, is so unpleasant that many people are put off seeking help at an early stage.

Not only is the new technology far less invasive, it also raises the possibility of automating the process.

Dr Steve Halligan, consultant radiologist at St Mark Hospital in Middlesex is planning the biggest test of the virtual system anywhere in the world.

He said: "We have a test that is rapid, and easy for the patient. They are on the CT scanning table just for a few seconds, and they don't need any sedation.

"They can have the test, get the results and go."

Charles Bunker is among the first patients on which the new technique has been tired.

He said: "Usually you are having a camera put up your backside, and you have got to have a light anaesthetic, whereas what I am doing here is lying on a table for about ten minutes.

"It is much better than the alternative, there is no doubt about that."
