MRI Scan - Magnetic Resonance Imaging

What is MRI?

Magnetic Resonance Imaging (MRI) is a unique way of showing structures in the body using a strong magnetic field and harmless low energy radio waves.  NO X-RAYS ARE USED.

What Happens During the Scan?

You lie on a special table which moves into the tunnel of the machine.  You need to keep very still during the examination.  The scan can take from 30 minutes to an hour.  At times the machine makes loud knocking noises. 

Some people find the tunnel in the machine confining.  Please inform staff at the time of your booking if you know you are very claustrophobic (uncomfortable in small spaces).  

Is Any Special Preparation Necessary?

All loose metal objects, safety pins, hairclips, watches and credit cards must be left outside the scan room.  Lockers are provided.

Patients will be required to complete a questionnaire.  If you answer "yes" to any questions it is very important that you inform staff at the time you make your appointment.
