MRI scanning

What is an MRI scan?
MRI scanning (Magnetic Resonance Imaging) is a type of scan that produces detailed images of inside the body through the use of radio waves and magnetic fields. Essentially it is a large magnet that you are positioned to lie inside during the scanning process .It can be used to scan almost any part of your body. The results of an MRI scan can be used to help diagnose conditions, plan treatments and assess how effective previous treatment has been.

Why is the 3T MRI scanner better?
Our 3T scanner produces images of a much higher resolution enabling us the capability of imaging smaller lesions and anatomy not always clearly visualised on 1.5T scanners, particularly in musculoskeletal, oncological, cardiac and brain imaging. The higher resolution imaging also means that it is no longer necessary to inject a dye into patients to pick up internal images for certain examinations.

With our 3T scanner, you can enter the MRI either feet or head first and with its larger magnet bore the whole experience of having an MRI far more comfortable and less claustrophobic for patients. The imaging process is also quieter and faster on a 3T scanner.

What happens during the MRI scan?

• You will be given a gown to wear for your scan and can prepare for your scan using our dedicated patient waiting areas and changing facilities.
• You will be asked to complete a safety questionnaire and it’s important to tell your radiographer before your scan if you have a:
  – Cardiac pacemaker
  – Artificial limb or joint
  – Artificial heart valve
  – Metal clips on blood vessels in your brain
  – Screws, plates or staples from previous surgery
  – Cochlear (inner ear) implants
  – Contraceptive coil fitted
  – If you are, or there is a possibility you may be, pregnant
  – If you are diabetic.
• Once ready, your radiographer will accompany you into the scanning room and ask you to lie down on the scanner table which will move into the tunnel-like MRI scanner to take the images. This may be head first or feet first and will depend on the area of the body being scanned.
• You will usually be given earphones or earplugs to wear as the scanner will make a noise whilst the scan is being taken. However, you will be able to talk to the radiographer performing the scan through an intercom, they will be watching the scanning process on a computer screen in the room next door and have visibility of the patients at all times.
• Your radiographer can talk to you whilst you are having your scan and put you at your ease but it is important that you remain still as any movement will blur the images produced. Depending on the number of scans required and the size of the area that is needed to be scanned, it can last between 15 and 90 minutes in total.
• Most people can have a MRI scan as it is low risk, even pregnant women after the first trimester and children. However, if you are claustrophobic, the process may make you feel uncomfortable and it is not always possible to use MRI scanning on people with implants, such as pacemakers.

When will I get the results?
All MRI scans are reported by a Consultant Radiologist.  We will ensure your results are sent back to your doctor or consultant who referred you for the x-ray quickly, usually within 48 hours, for them to discuss with you.
