What should you know about an MRI wide-bore scanner?

The bore is the central opening of the MRI scanner. A wide-bore design provides more space around the body than a narrower design, although the table still moves into the magnet and the scan remains enclosed. It may suit people who feel anxious in tight spaces, have a larger body size, or need a position that is easier to maintain. The scanner still uses magnetic fields and radio waves, and image quality depends on the body area, the equipment, and staying still.

When booking, ask for the scanner's opening size, table weight limit, and whether the required body part can be positioned comfortably. Tell staff about metal fragments, implants, electronic devices, pregnancy, kidney problems, and previous contrast reactions. Wear clothing without metal and remove jewellery and removable devices. Ear protection is provided because MRI sounds can be loud. If anxiety is a concern, discuss practical support before the appointment; do not take a sedating medicine unless it has been prescribed and explained.

A wide-bore scan is planned imaging, not emergency treatment. Seek urgent help for sudden weakness, severe breathing trouble, fainting, new confusion, or rapidly worsening pain. During or after the scan, alert staff immediately for severe distress, chest symptoms, or a possible contrast reaction such as facial swelling or breathing difficulty. Tell the ordering team if pain or other symptoms worsen while you wait.

Will a wide-bore scanner provide the sequences needed for my body area? Can the centre confirm the opening and table limits? Will contrast or special positioning be required? What can I do if I become anxious? When and how will the report be explained?
