What does an MRI scan machine look like?

The scanner has a padded table, a circular opening, and room around the head or body being examined. The radiographer operates it from a nearby room and can speak with you through an intercom. Coils may be placed around the body part to help collect the signals used to make images. The table may move in and out several times as different views are recorded.

The space can feel enclosed, although both ends of the tunnel are open. The equipment makes repeated loud tapping, thumping, or humming sounds. These sounds are expected, and earplugs or headphones can help. You can usually communicate with staff and may have a call device for assistance.

Wear simple clothing without metal and leave jewellery, keys, phones, bank cards, and hair accessories outside the scan room. Complete the safety questionnaire carefully. Mention any implanted device, shrapnel, surgical clip, medication pump, hearing device, or metal in your eye. Tell staff if enclosed spaces worry you; they can discuss positioning, reassurance, or other arrangements before the appointment. Follow specific instructions if contrast or fasting is planned.

Tell the team immediately if you feel burning, pulling, chest discomfort, or sudden distress during the scan. After contrast, report hives, facial swelling, breathing trouble, or faintness urgently. Separately, seek urgent care for a seizure, sudden one-sided weakness, new confusion, or a severe sudden headache rather than waiting for routine results.

Ask whether your head or whole body will enter the tunnel, how long you should expect to remain still, and whether contrast is needed. Ask what support is available if you feel claustrophobic and how results will be shared.
