Magnetic resonance imaging (MRI) is a type of scan that uses powerful magnets and radio waves to produce detailed images of the soft tissue inside our bodies. MRI scan is non-invasive, (meaning it doesn’t pierce the skin) painless and one of the safest scans available.

Because no radiation is used during an MRI scan, this makes it extremely safe. However due to the large magnetic force used in MRI scans, precautions are needed, and some people may not be suitable for an MRI scan.

Before you have your scan

Before you have your MRI scan the technician will ask you some questions. Be sure to answer them accurately and discuss any questions or concerns you may have.

Metal Objects

Before your MRI you will be asked to remove any metal objects such as jewellery, watches, hearing aids, dentures, pocket change, and clothing like zips, belts, and underwired bras. You will also be asked about any previous surgeries and internal devices such as a pacemaker, implantable cardioverter-defibrillator (ICD) cochlear implant, and intrauterine device (IUD). It`s also important to mention if you have or may have any bullets or shrapnel in your body.

Pregnancy

MRI scans are not normally recommended during pregnancy. Be sure to tell your technician if you are (or may be) pregnant or breastfeeding.

Allergies

In some MRI scans a contrast dye is administered via a drip in your arm to give the doctors more information. Allergies to the dye are rare and usually mild, but be sure to tell your technician if you suffer from any of the following:

·       Previous reactions to contrast or any allergies to food or medication

·       Medications or supplements you take regularly

·       Any pre-existing medical conditions

Claustrophobia

If you a worried about feeling claustrophobic in the MRI scanner, discuss this with your technician before your scan. Simple measures like, a clear explanation of the procedure and what to expect, listening to music, or even having someone with you during the scan can help.
