Private magnetic resonance imaging (MRI) scan

What is an MRI scan?

An MRI uses a strong magnetic field and radio waves to produce detailed images of the inside of your body. 

Unlike X-rays or computed tomography (CT) scans, MRI doesn’t use radiation. 

It is particularly helpful for examining the spine, brain, joints and soft tissues, but it can also assess other areas.

Sometimes, contrast dye might be used. The dye shows up on the scan and gives us more detailed pictures, particularly of your blood vessels. The injection is given by inserting a small needle into your arm or hand.

Preparing for your MRI scan

Before your scan, the radiographer will explain the procedure and make sure you’re happy to proceed. If contrast dye is needed, you’ll be asked to sign a consent form. You’re welcome to ask questions at any stage.

Some preparations to consider before your MRI scan include: 

• Clothing and belongings – you’ll change into a gown and remove jewellery, watches and other metal items that you can keep in a private locker
• Medical devices – please let us know if you have a pacemaker, cochlear implant or insulin pump (for diabetes), as these may affect MRI suitability

If you are pregnant, scans are only carried out if clinically urgent. Our team will advise you.

Our imaging specialists will guide you through every step, so you know exactly what to expect and feel comfortable on the day.

What happens during my MRI scan?

When you arrive, you will be asked to change into a gown and remove items like jewellery, watches or hair clips. Our team will help you get comfortable on the scanner bed and make sure you feel at ease.

The scan itself is painless. The machine makes loud tapping noises, but we’ll provide earplugs or headphones, and you can listen to music if you’d like. Staying still helps us capture the clearest images.

Most scans last between 15 and 60 minutes, depending on the area being examined. You’ll be able to talk to the radiographer at any time, and if you feel uncomfortable, pressing the buzzer will pause the scan immediately.

After your MRI scan

When your scan is complete, you can return to your normal routine, including eating and drinking as usual.

If you received a contrast dye injection, allergic reactions are rare but can occur within two days. If you notice a skin rash or difficulty breathing, seek emergency medical care.

What are the benefits of an MRI scan?

MRI scans provide highly detailed images of the body, offering far more information than a standard X-ray. They are particularly useful for examining the spine, brain, joints and soft tissues, but can also assess many other areas. 

Unlike other imaging scans (such as X-rays or CT scans), MRI does not use radiation.
MRI is a very safe procedure for most people. Before your scan, you’ll complete a safety questionnaire so our team can confirm it’s safe for you.

Frequently asked questions (FAQs) about MRI scans

Here are some common questions patients ask us about MRI scans, with clear answers to help you feel prepared and reassured. 

When will I get my MRI scan results?

Your images will be reviewed by one of our consultant radiologists, and a detailed report will be sent to your referring doctor within 48 hours. Your consultant will then discuss the results with you and explain any recommended next steps.

Will I need an injection?

Some MRI scans require a contrast dye to highlight specific tissues or blood vessels. This is given through a small needle in your arm or hand.

Can I eat and drink before my scan?

In most cases, you can eat and drink normally and take your usual medication. If any special preparation is needed, we’ll explain it when we confirm your appointment.

Is an MRI scan safe?

MRI is very safe for most people. It may not be suitable if you have certain implants, such as a pacemaker, or if you are pregnant. Our team will check your suitability before the scan.

You can also watch this short MRI safety video from Siemens Healthcare for more information.

Can I bring my children?

We do not have childcare facilities, and children cannot enter the scan room. If you need to bring children, please ensure another adult can supervise them during your appointment. Without a supervising adult, your scan will need to be rebooked.

What if I need extra support with communication?

Your comfort and understanding matter to us. If you need an interpreter or information in another language or format, we’ll arrange this for you – just let us know before your appointment.

Are there any alternatives to an MRI scan?

If you cannot have an MRI scan, for example, due to a pacemaker or claustrophobia, the radiologist may recommend another imaging test, such as an X-ray, CT scan or ultrasound.
