ABOUT MRI SCANS

What is an MRI?

Magnetic resonance imaging (MRI) is a non-invasive, pain-free, diagnostic scan which captures images of the soft tissue, organs, muscles, tendons, cartilage and bones in your body. MRI is one of the safest medical procedures available as it does not use radiation to produce images, unlike a CT Scan or an X-Ray. An MRI machine uses a strong magnetic field and radio waves to capture various images (known as slices), which can be combined to produce a 3D image of a particular body area, so it can be more effective than other imaging scans at detecting abnormalities.

What is an MRI used for?

An MRI is typically requested for the below body areas:

Brain – An MRI of the brain can be very useful to determine any damage from a head injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, hormonal abnormalities, brain tumours, or the cause of persistent headaches or migraines.

Head – An MRI of the head can be used to investigate various symptoms, such as pain or swelling, in the eyes, ears, mouth, nose and sinuses.

Neck – An MRI of the neck (cervical spine) can be very useful to determine various conditions of the cartilage and bone structure resulting from injury, disease, or ageing by imaging bones, soft tissue, nerves and disks.

Spine – An MRI can be helpful in diagnosing various conditions of the cartilage and bone structure resulting from injury, disease, or ageing by imaging bones, soft tissue, nerves and disks. The MRI scan can highlight any abnormalities in the spinal canal or spinal cord and assess the spinal disks to determine whether they are bulging, ruptured or pressing on the spinal cord or surrounding nerves.

Abdomen – An MRI can be useful for investigating persistent abdominal pain for various diseases and disorders, like cysts, tumours and inflammation. An abdominal scan can provide more insight into pain or discomfort in your kidneys, pancreas, spleen, liver, gallbladder, uterus, ovaries, prostate and/or bladder.

Joints – An MRI of your joints can be useful in investigating pain, weakness or swelling of joints by examining bones, joints, and soft tissues such as cartilage, muscles, and tendons for injuries or the presence of structural abnormalities. We can scan ankles, elbows, hands, fingers, feet, hips, pelvis, Sacroiliac (SI) joints, shoulders and wrists.

Is an MRI safe?

MRI is one of the safest medical procedures available as it does not use radiation (unlike a CT Scan or an X-Ray) but instead uses a strong magnetic field and radio waves to capture various images (known as slices), which can be combined to produce a 3D image of an area in the body.

Whilst an MRI scan is a very safe procedure, there are some exceptions such as patients with cardiac pacemakers and certain surgical implants, e.g. cochlear implants who cannot be scanned. You will be asked to complete a safety questionnaire before your scan to make sure it is safe for you to be scanned.

Why have an MRI, rather than a CT Scan or X-Ray?

A Magnetic resonance imaging (MRI) scan is a combination of a strong magnet and radio waves which produce detailed pictures of inside the body. But unlike X-rays and Computed Tomography (CT) scans, MRI scans don’t use radiation, which make this medical procedure considerably safer. The lack of radiation makes an MRI scan particularly valuable when frequent imaging is required for diagnosis or ongoing therapy, especially in the brain or spine.

With an MRI, certain parts of the body are seen more clearly than with a CT or X-Ray, such as the brain, spinal cord and nerves, muscles, ligaments and tendons. This makes an MRI particularly useful for diagnosis, so that your chosen Healthcare Professional can find the best treatment options for you.

Can you scan me without putting my head in the scanner?

Dependent on the area being scanned, we endeavour to scan feet-first whenever possible. If you think you may be claustrophobic (have a fear of enclosed spaces), please take a look at the Open MRI service that we offer.

Do you have an MRI for patients who don't like enclosed spaces?
