Magnetic Resonance Imaging (MRI): Purpose, Procedure, and Costs in the UK
Did you know that England has 656 MRI scanners across NHS providers, helping millions of patients receive important diagnostic imaging every year.
An MRI is a medical imaging test that uses powerful magnets and radio waves to create detailed pictures of the inside of your body. Unlike X-rays and CT scans, an MRI scan does not use ionising radiation. It is one of the most accurate imaging tests available today.
This guide explains to you the purpose of an MRI scan, how much it costs in the UK and what you can expect before, during and after the procedure.
What Is the Purpose of an MRI Scan?
The main purpose of an MRI scan is to give detailed pictures of the inside of the body to doctors. Unlike some other scans, MRI shows soft tissues very clearly. This helps doctors find problems that may not appear on X-rays.
Doctors may recommend an MRI scan to:
- Find the cause of pain or other symptoms.
- Diagnose injuries and diseases.
- Monitor long-term health conditions.
- Plan surgery or other treatments.
- Check how well the treatment is working.
Because MRI scanning produces detailed images, it helps doctors to make better decisions about your care.
“Medical imaging is central to modern healthcare because it helps doctors diagnose disease earlier and more accurately.”
— Dr Katharine Halliday, Former President, Royal College of Radiologists
1. MRI for Brain and Spine
An MRI scan is often used to examine the brain and spinal cord. It gives clear images of nerves, brain tissue and the spine.
Doctors may use MRI scanning to diagnose the following:
- Stroke
- Brain tumours
- Multiple sclerosis (MS)
- Epilepsy
- Brain injuries
- Slipped discs
- Spinal cord problems
- Nerve compression
2. MRI for Joints and Bones
An MRI scan is commonly used for bones, muscles and joints. It helps doctors to identify:
- Torn ligaments
- Muscle injuries
- Tendon damage
- Sports injuries
- Arthritis
- Cartilage damage
- Bone infections
3. MRI for Heart and Blood Vessels
Doctors also use an MRI scan to examine the heart and blood vessels. It may help to diagnose the following:
- Heart muscle disease
- Heart damage after a heart attack
- Blood vessel narrowing
- Congenital heart conditions
- Poor blood flow
4. MRI for Internal Organs
An MRI scan can produce detailed images of many internal organs. These include:
- Liver
- Kidneys
- Pancreas
- Prostate
- Uterus
- Ovaries
Doctors use MRI scanning to check for inflammation, cysts, tumours and other changes inside these organs.
What Is The Procedure of an MRI Scan In The UK?
Whether you book your appointment through the NHS or a private clinic, MRI scanning usually follows the same steps. Most scans take between 15 and 90 minutes, depending on the part of the body being examined.
Here is the procedure of an MRI scan:
Before The Scan
Before your MRI scan, the healthcare team will explain the procedure and ask you some questions. You may be asked to:
- Complete a safety questionnaire.
- Tell staff if you have a pacemaker, metal implant or cochlear implant.
- Inform staff if you are pregnant.
- Remove jewellery, glasses and other metal items.
- Change into a hospital gown if needed.
During The Scan
During your MRI scan, you will lie on a scanning table and a radiographer will use cushions or support to keep you comfortable. The table slowly moves into the scanner.
While inside the scanner:
- You must stay as still as possible.
- The machine makes loud tapping sounds.
- You will wear earplugs or headphones.
- You can speak to the radiographer through an intercom at any time.
After The Scan
After your scan is completed, the scanning table moves out of the scanner and the staff help you sit up if you feel dizzy. After this you can get dressed and go home straight away. Your scan results are usually sent to the doctor who referred you within 2 to 3 weeks then your doctor will explain the results at your follow-up appointment.
How Much Does an MRI Scan Cost in the UK?
An MRI scan is usually free if you have it through the NHS. If you choose a private clinic to avoid long waiting times, the cost is typically between £200 and £450 for one body area. On average, a private MRI scan costs about £395.
Case Study: Kelly Suffered Back Pain With 30 years
Kelly, who lives in Scotland, said that I have been living with pain for about 30 years. When I was a teenager, I had a bad fall that injured my spine. Later, I fell from a horse and was also hurt in a road traffic accident. These accidents caused more damage to my back.
She said that her pain became worse over time, so her doctors arranged an MRI scan. After the scan the results showed that Kelly had spinal stenosis and damaged discs in her lower back. The scan helped doctors to understand the cause of her pain and choose the right treatment.
After getting proper treatment and care, Kelly said that seeing the MRI scan results made her feel relieved because doctors could finally see what was causing her pain. She then received the care and support she needed to manage her condition.

An MRI scan is one of the most useful tests available in modern healthcare. It gives detailed images of the body’s organs, muscles, joints and brain without using radiation.
