What should you know about open bore mri scanner?

MRI uses a strong magnetic field and radio waves to create detailed images; it does not use x-rays. You usually lie on a table that moves through the scanner while it makes loud tapping or knocking sounds. Staying still helps prevent blurred images. Some examinations use contrast medicine, which is given only when the clinical team considers it useful.

Open-bore equipment can provide more space around the body than a conventional design, but the opening and image performance vary between machines. An [MRI Scanner](/technology/mri-scanner/) or [MRI Scan](/treatments/diagnostics-and-staging/mri-scan/) page can help you understand the general examination.

Tell the imaging team about pacemakers, implanted devices, metal fragments, clips, hearing devices, pregnancy, kidney problems, allergies and previous reactions to contrast. Remove jewellery, watches, cards and other metal items as instructed. Wear clothing without metal fasteners when possible. Ask whether a companion can stay nearby and agree on a way to signal if you need help.

For breast concerns, the team may recommend [Breast MRI](/treatments/diagnostics-and-imaging/breast-mri/), which has preparation and positioning requirements specific to that examination.

Before the appointment, contact the imaging centre if you have an implant, possible metal exposure, severe claustrophobia, or may need help transferring onto the table. After contrast, seek medical advice for trouble breathing, facial swelling, widespread rash or feeling faint. Report pain or a new symptom during the scan rather than trying to tolerate it silently.

Ask why MRI is recommended, whether an open-bore machine is suitable for the body area being examined, whether contrast is needed, how long the appointment may take, and when results will be discussed. Tell the team what would help you remain still and comfortable.
