MRI introduction MRI History MRI how it works MRI patient info

Magnetic Resonance Imaging (MRI) is an imaging technique that uses magnetism and radio waves to produce images of parts of the body. It does not rely on the use of x-rays as in CT scanning. The first MRI images of the body were produced in the late 1970’s. Since then MRI has developed to become a highly sophisticated imaging technique capable of producing very detailed images of the body.

MRI involves a patient being passed through the centre of the cylinder shaped MRI scanner. The MRI scanner is able to produce finely detailed images of the body especially soft tissues and is very valuable for the diagnosis of a range of medical conditions. MRI is the imaging technique of choice to view the brain and spinal cord. It is also very useful for viewing joints and may also be used to view other organs such as the liver or kidneys. A more advanced form of MRI – “MRI Angiography” is a highly accurate technique for examining the heart and blood vessels.                      A photograph of an MRI scanner

MRI is used throughout the world and is a relatively safe technique. However, there may be certain circumstances why a patient may not be able to undergo MRI and this is discussed in the patient information section.
