Your first MRI: what to know before the scan
Documents, implants, preparation and contrast: a practical guide to your first visit.
Preparation depends on the examination
There is no single preparation rule for every MRI. Instructions about eating and drinking depend on the body area and planned procedures. When booking, ask whether fasting or any other preparation is needed. Do not change your medicines on your own; consult your doctor, especially if sedation is planned.
Bring identification, your referral if available, medical records, previous reports and images. Explain your main concern and when it began: this context helps connect the scan with a specific medical question.
What the team needs to know
Before entering the MRI room, disclose all implants and electronic devices, metal fragments, operations and pregnancy or possible pregnancy. Bring documentation identifying the model of any implant. Do not decide compatibility yourself: similar devices may have different conditions for safe scanning.
Remove jewellery, watches and other metal items as directed. Phones and electronics stay outside the scanning room. If you are unsure about clothing, cosmetics or an item you are carrying, ask a staff member.
What happens during scanning
During MRI you need to stay still and follow the technologist’s instructions. The scanner makes loud rhythmic sounds, and appropriate hearing protection is used. Before starting, ask how to contact staff if you feel uncomfortable during the examination.
The duration depends on the area, protocol and need for additional images. Mention pain, anxiety or claustrophobia when booking. Do not take sedatives on your own before your visit.
If contrast is planned
Contrast is used for a medical reason, not automatically for every patient. Tell the team about kidney disease, previous reactions to contrast and other relevant conditions. A blood test to assess kidney function may be requested; its necessity and how recent it should be are determined individually.
After the scan, share the report with your treating doctor. Do not draw conclusions from an isolated term in the report: the meaning of findings depends on symptoms, examination and previous investigations.
