Cardiology
Your consultant has requested that you attend for a Cardiac MRI scan. This leaflet is designed to explain what the examination involves. The examination will be carried out in the MRI department at The James Cook University Hospital or the Friarage hospital, Northallerton.
What is a Cardiac MRI scan (CMR)?
CMR stands for Cardiac Magnetic Resonance Imaging (also known as MRI). The scan uses magnetic radio waves and a computer to take detailed moving and still images of your heart and blood vessels. It is an advanced way of producing an image that will help your doctor to make a diagnosis.
Is there anything I should tell the staff?
Please contact us if you:
- Are pregnant or think you might be
- Are currently breast feeding
- Have a cardiac pacemaker
- Have an internal defibrillator device (ICD)
- Have a cerebral aneurysm clip
- Have a programmable shunt
- Have any implanted metallic devices (for example, implant or neuro-stimulator).
- Have or have ever had shrapnel or other metal fragments in your body, especially in your eyes
- Weigh over 127kg (20 stones)
- Are claustrophobic
- Currently have any kidney function impairment.
Preparation for the scan
- You can eat, drink and take any medication as normal
- You will be asked to fill out a safety questionnaire. A member of staff will go through this with you and explain the examination
- You will be asked to change into a hospital gown and lock property in a locker. South Tees does not accept responsibility for any loss of clothing, money, valuables or personal possessions belonging to staff or members of the public
- You must remove any metallic objects (jewellery, watches, glasses, hairpins, keys, coins, credit cards, metal dentures)
- You will have ECG electrodes placed on your chest to monitor your heart rhythm. Sometimes we may need to shave your chest
- It is often required that a small plastic tube (cannula) be inserted into a vein in your arm or hand. This is for the administration of a contrast solution that enhances the quality of the scan. As with all drugs there is a slight risk of an allergic reaction, which may vary from nausea to, very rarely, a more severe reaction. It will not make you sleepy or prevent you from driving.
What the scan involves
You will be lying on a firm table. The radiographer will position you on the table and then move the table to the centre of the CMR machine. The inside of the machine is like a tunnel which is well lit, open at both ends and has air blowing through it. You will be given headphones and earplugs to wear as the scanner makes a loud knocking noise as it takes the images.
Throughout the duration of the scan, you will be given breathing instructions and must remain still. You will also be given a nurse call buzzer to alert the radiographer to any problems.
Does it hurt?
No, some people may experience a mild sensation such as a light vibration or tingling of the skin. CMR is safe, pain free and has no known side-effects.
How long does it take?
The procedure ranges from 60 to 90 minutes. If you attend early there is no guarantee that you will be seen before your appointment time. If you arrive late there is a chance that we might need to re arrange your scan.
What happens after the scan?
Once the examination is complete, you will be removed from the CMR machine, the cannula and ECG will be removed. You can collect your belongings and leave.
When will I get the result?
The images are examined by a cardiologist, who will report on the findings. The report is then sent to the doctor who referred you.
Transport has not been arranged for this appointment. If an ambulance is required, please contact your GP at least 48 hours before the appointment date.
All car parks are pay and display.
