what to expect from your MRI scan

MRI

What is MRI?

MRI stands for Magnetic Resonance Imaging, an imaging technique used to visualise the soft tissue inside your body.

How does MRI work?

MRI combines a powerful magnet with radio-frequency pulses. These collect signals that are then processed by a sophisticated computer to form pictures of the inside your body.

What is MRI used for?

MRI gives highly detailed pictures of the soft tissues within the body, for example muscles and ligaments. This capability means Doctors can use MRI in a wide range of investigations: from slipped discs and brain tumours, to painful or injured joints to the assessment of blood flow.

What do I need to do before my MRI scan?

Unless you are told otherwise, no special preparation is needed for your scan and you may continue to eat and drink as normal and take any prescribed medicine.

It is helpful if you can come for your scan in clothing that has no metal parts, such as hooks or zips. If this is not possible, then you will need to change into a hospital gown. We would also request that you leave any valuable possessions at home.

Before your scan you will need to complete a safety questionnaire. Due to the powerful magnet that is used in MRI, not all patients can be scanned - such as those with surgical clips, a pacemaker or metal fragments in the eyes. If you are concerned please contact our team before your scan appointment.

What will happen during your scan?

For your scan, you will lay down on a comfortable scanning bed that will slowly move through a doughnut shaped ring called a gantry. You will experience no discomfort or pain, but may hear quite loud mechanical sounds from the scanner.

The technologist operating the scanner can both see and hear you throughout the procedure so if you have any concerns, you only have to say. You can expect to be in the scanner for between 20 and 40 minutes.

What can you expect after your scan?

The results of you scan will be analysed by a Radiologist who will provide your doctor with a comprehensive report. Your doctor will then discuss the findings of the report with you and plan any treatment or next steps.
