  • What is MRI?

    MRI stands for Magnetic Resonance Imaging which is a diagnostic test that uses a very strong magnetic field and radio waves to provide cross-sectional images of internal organs and body tissues. It allows doctors to see inside your body from many different angles to visualise your internal organs without any invasiveness. MRI does not use ionising radiation and therefore has none of the potentially harmful side effects of x-rays. MRI can produce very clear diagnostic images in virtually all areas of the body.
    The MR Therapy Centre is based in London and provides MRI Scan and other services. You can also find more information on cost of our MRI Scans on this website.
  • Does the machine use x-rays?

    No. There are no x-rays or radiation used during MRI scanning.
  • Will an MRI scan hurt?

    No. The MRI scan is non-invasive and so is painless. For some patients, the doctors may need to use a special contrast dye (gadolinium) to help visualise parts of your body better in which case you would need a cannula (small needle put in the vein of your hand through which the dye can be injected).

    All patients are in constant contact with the scanning team via speaker phone so you can let the radiographer undertaking your scan know if you feel uncomfortable. You are also given a buzzer which you can activate at any time to stop the scan and be removed from the scanner.
  • Who will carry out my MRI scan?

    When you arrive at the department you will be met by one of our reception team who will ask you to complete some short paperwork before your scan. The MRI scan itself will be carried out a senior radiographer who is an expert in MR imaging. All of our radiographers have substantive contracts with Imperial College Healthcare NHS Trust and are registered with the Health Professions Council.

    The MRI scan will be reported by a Consultant Radiologist who is a specialist in the area being scanned. All of our radiologists hold a substantive NHS Consultant post. We do not outsource our scans to doctors who work outside the UK.
  • Is the MRI scanner closed?

    The MRI scanner is shaped like a round cylindrical tunnel but is open at both ends. You are not shut inside the machine at any time.
  • What does the MRI scanner sound like?

    During the MRI scan the machine is very loud as it makes ‘knocking’ noises during scans and then becomes quiet in between scans. Depending on the type of scan you have you will either receive ear plugs to help reduce the noise or may be able to use the inbuilt stereo system to listen to music during your scan.
  • How long does an MRI scan take?

    MRI scans vary depending on the area of your body that is being scanned but typically last between 20mins and 60mins. You will be informed how long your scan should take at the time of booking.
  • Do I need to lie still during the MRI scan?

    You do need to remain as still as possible during the scan. If there is lots of movement on the images they need to be replanned and taken again which will mean your scan time will be longer. If you are finding it difficult to remain still or have health problems that mean lying in one position is difficult then please let the scanning staff know so that they can help make you as comfortable as possible and let you know in between scans when it is ok to adjust positions.
  • Do I have to hold my breath during the scans?

    No. Although you need to remain as still as possible you should continue to breathe as normal throughout your scan.
  • Will I be told the results of the scan straightaway?

    Your MRI scan will be taken by a fully qualified, senior radiographer however they are not doctors and cannot therefore interpret your scan to determine the result. The images are sent to a Consultant Radiologist who will ensure your scan is reported and returned to your referring doctor no longer than 48 hours after your test.
  • Will I be alone during my MRI scan?

    Although you are usually in the MRI scanning room alone during your test you are in full communication with the radiographer undertaking your scan so that you can talk to each other throughout. If you are particularly anxious about your test it may be possible to have one friend or relative go into the scanning room with you, however they would need to be assessed in advance to ensure it is safe for them to do so (i.e. that they do not have a heart pacemaker or other incompatible equipment).
