Do you need a referral for an MRI scan?

A referral gives the radiology team the clinical question, the body area to examine and relevant medical details. Some centres accept direct bookings for selected scans, while others ask for an order from a doctor. Contact the centre before attending so it can confirm its booking requirements.

The request helps the radiologist choose an appropriate MRI protocol and decide whether contrast material may be useful. It also allows the centre to check safety details, including implanted devices, metal fragments, previous operations, pregnancy or possible pregnancy, kidney problems and earlier reactions to contrast material.

An MRI uses a strong magnetic field and radio waves rather than ionising radiation. The exact preparation varies with the body part and scan protocol, so instructions may include removing metal items, fasting or bringing earlier imaging.

Call the imaging centre and state which body area is being assessed and why. Ask whether it needs a signed referral, recent blood tests or previous scan reports. If a referral is required, arrange an appointment with the clinician managing the symptom or condition.

Tell the booking team about pacemakers, implanted pumps, aneurysm clips, hearing implants, metal injuries, severe claustrophobia or difficulty lying flat. Do not stop prescribed medicines unless the clinical team gives specific instructions. Read more about an MRI Scan and what the examination involves.

Seek urgent medical assessment for sudden weakness or numbness on one side, new difficulty speaking, a seizure, severe breathing difficulty, loss of consciousness, or a sudden severe headache. These symptoms need prompt clinical assessment; arranging an outpatient MRI should not delay emergency care.

Ask which body area and clinical question will appear on the request, whether contrast is planned, what preparation is needed, and how results will reach the referring clinician. If enclosed spaces are difficult for you, ask what support or scanner options are available before the appointment.
