– What is an MRI Scan?
Magnetic resonance imaging (MRI) uses powerful magnetic fields and radio waves — not ionising radiation — to produce highly detailed images of the body’s internal structures. It is particularly superior for imaging soft tissues such as the brain, spinal cord, nerves, muscles, tendons, cartilage, and abdominal organs.
During the scan, you lie inside a large cylindrical magnet. The machine produces a series of loud knocking sounds as sequences are acquired — ear protection is always provided. The scanner is open at both ends and well-lit, though patients with significant claustrophobia should discuss this with us before booking.
Some MRI scans require a contrast agent (gadolinium) injected into a vein to enhance the visibility of certain tissues or abnormalities. Where contrast is not required, no cannula is needed at all — the scan is entirely non-invasive.
Types of MRI Scan
We offer a wide range of ultrasound examinations. Please specify the area of concern when booking.
Your Appointment
Many modern pacemakers and implants are MRI-conditional, meaning a scan can be performed safely under specific conditions. Some older devices are not MRI-compatible. You must disclose all implants and devices on your safety questionnaire. Our team will check the compatibility of your specific device before your appointment. Dental fillings, joint replacements and most surgical clips are generally safe.
Yes — MRI scanners make loud repetitive knocking and banging sounds as the imaging sequences run. This is entirely normal and not a sign of any problem. We always provide ear protection (earplugs or headphones) and in most cases you can listen to music through headphones to help pass the time more comfortably.
Many claustrophobic patients successfully complete MRI scans with the right support. The scanner is open at both ends and well-lit. We can arrange for a companion to be present in the room (screened for metal), offer headphones with music, provide a fan for airflow, and advise on positioning strategies. For severe claustrophobia, your GP may be able to prescribe a mild anxiolytic medication. Please discuss this with us when booking.
Fasting is generally not required for most MRI scans. However, abdominal MRI scans (particularly liver, MRCP, or small bowel studies) may benefit from a period of fasting to reduce bowel motion artefact. Where fasting is required, our team will provide specific instructions when you book.
mpMRI of the prostate is the recommended first-line imaging investigation for suspected prostate cancer, as it can identify and grade suspicious areas before biopsy, reducing the number of unnecessary or targeted biopsies. It typically includes at least three MRI sequences (T2, diffusion-weighted, and dynamic contrast-enhanced), reported using the standardised PI-RADS scoring system. Please discuss with your urologist or GP whether this investigation is appropriate for you.
