MRI Scanning

Magnetic Resonance Imaging (MRI) is a scanning method involving the use of a powerful magnetic field, radiofrequency waves and computers to produce detailed cross sectional images of internal body structures, without the use of ionising radiation.

These scans can be performed on most body parts and allow demonstration of soft tissue structures including; muscle, spinal cord, intervertebral discs, cartilage and ligaments as well as organs including the heart, bowel and brain.

MRI scans are not suitable for all patients and contraindications include;

• Patients with pacemakers and some heart valves (please inform us of valve model if it applies to you)
• Patients with aneurysm clips
• Pregnancy
• Metal within the eye (an X-Ray may be required if you are in doubt)

In order to prevent accidents due to the strong magnetic field, all patients will be asked to complete a thorough safety questionnaire regarding previous medical history. This will be discussed between you and the radiographer when you arrive. You will be asked to remove all metallic objects which will be kept in secure lockers and change into a gown prior to entering the scan room.

Most examinations are between 25 - 45 minutes duration and it is vital you remain still throughout. When the scan is being performed the scanner can be very noisy and we will provide you with either earplugs or headphones. In some cases it may be necessary to administer a contrast agent (dye) to allow better visualization of vessels, this will be explained in detail at your appointment and you will be asked to consent to this injection.

Our scanning services include all types of body, orthopaedic and neurological scans, most of which require no specific preparation prior to the scan. We also perform a range of more specialised examinations including the bowel, liver, breasts and heart, for these scans specific preparation may be necessary and you will be informed of this when booking.

Cardiac MRI

Cardiac MRI can be used to evaluate the structure of the heart and assess how it is performing. Images obtained can assess the left and right ventricular function as well as myocardial scarring or fibrosis and previous myocardial infarction. MRI images of the heart are generally clearer and more detailed than some more invasive imaging methods making it an invaluable tool in the early diagnosis and evaluation of cardiac abnormalities, especially those involving the heart muscle.

This scan can take up to an hour to perform and you will be asked to arrive early in order to have an echocardiogram (ECG).

For this test it is essential that you do not consume any caffeine for 24 hours prior to the scan. In some instances it may be necessary to administer a medicine to artificially stimulate your heart so we will need information regarding any other medication that you are taking.
