Magnetic Resonance Imaging (MRI) scans

Magnetic resonance imaging (MRI) is a specialised imaging technique that does not involve the use of radiation, instead it uses a special high field magnetic to generate an image or picture. It is similar to CT scans in that it produces an image of a cross-section, or slice, of the body. MRI can produce images in many different planes (angles) within the body helping to identify any possible abnormalities. The information passes to a computer which then produces a picture of the internal structure of the body. The pictures are displayed on a TV screen and can be examined by the radiologist. The scanner consists of a long ‘doughnut’ shaped structure, through which you pass on a couch. Some people find this claustrophobic but generally with earplugs, eye patches and headphones to listen to music most people are able to have an MRI. The MRI differs from CT scanning, and is often complimentary, it is better at looking at the differences between the soft tissues within our bodies. As such it has a particular role in the imaging of the anal complaints (cancer, fissures & fistulas), rectal (polyps, cancer, fistulas), pelvic floor injuries (commonly after childbirth) and organs within the abdomen & pelvis. Most scans require no preparation and no injection (occasionally it is required). The examination takes between 1-1.5hrs.
