MRI

Overview

Magnetic Resonance Imaging (or MRI) produces detailed cross-sectional images of the body by using two naturally occurring forces to generate the images – magnetic fields and radio waves. During the scan, a computer processes the signals received from protons in the body and produces a series of images interpreted by a radiologist.

What to expect

Before

You will be advised when making your appointment the approximate duration of your scan and specific preparation. Most scans take between 30 – 45 minutes.

During

On arrival, you will be given an MRI Patient Questionnaire to complete which will be checked by the MRI technologist. You will be asked to remove all jewellery and metal objects and change into one of our gowns. All valuables will be safely locked away.

The MRI scanner is large and open and makes a continuous loud knocking sound while scanning. You will be provided with earplugs and music headphones to reduce any discomfort from the noise and a buzzer to contact the MRI technologist at any time throughout the procedure.

During the scan it is vital that you keep still. If you have difficulty lying flat, have poorly controlled pain or suffer from claustrophobia, please discuss this with us prior to your scan.

​In some cases, the administration of a contrast agent is required through a vein in your arm. If this is required, you will be fully informed and asked for consent prior to your scan.

After

After the scan, you can resume normal activities. 

Results of your scan will be sent to your referring Specialist usually within 48 hours, unless alternative arrangements have been made. 

Risks

​Due to the strong magnetic field of the scanner, some patients may not be able to have an MRI scan. Please contact us immediately if you have a cardiac pacemaker, cochlear implants, metal fragments in the eye or surgical clips on blood vessels in the brain.
