An MRI can feel daunting if you dislike enclosed spaces. The scanner is noisy and you need to lie still, but you can speak to the radiographer and there are practical steps that may help. Tell the provider about your anxiety before the appointment so they can discuss suitable options with you.
If you are worried about feeling enclosed during an MRI, tell us before your appointment. Our team can explain what to expect and help you prepare; appointments can usually be arranged within 1–3 days, with results within 3 days of your scan.
Why can an MRI feel difficult?
During many MRI examinations, the part of your body being scanned is positioned inside a tunnel-like scanner. You will hear repeated knocking or buzzing sounds and need to keep still to produce clear images. Some people feel anxious because of the space, the noise or the length of the examination.
The experience varies depending on the scanner, body part and protocol. Ask the provider to explain how you will be positioned and approximately how long the scan is expected to take.
Tell the team before your appointment
Let the booking team or referring doctor know if you have claustrophobia, panic attacks or previous difficulty completing an MRI. They can explain what support is available and whether the planned examination is suitable. Do not wait until you are already in the scanner to raise a concern if you can tell them beforehand.
Some people may be offered medication to help with severe anxiety, but this needs to be arranged through an appropriate doctor and may affect whether you can drive afterwards. Do not take sedatives or someone else’s medication without medical advice.
Practical ways to prepare
Ask what the scanner looks like and whether a support person can accompany you to the department. Wear comfortable clothing without metal if the provider permits it, and follow all safety instructions. If you use breathing or relaxation techniques, practise them before the appointment.
During the scan, focus on slow, steady breathing or a familiar mental image. Ask the radiographer how you can communicate if you need help; you will usually have a way to speak to the team. Headphones or ear protection are provided because MRI scanners are loud.
Can the scan be adapted?
Depending on the clinical question and equipment available, the team may consider a different scanner arrangement or other practical adjustments. Not every scan can be performed on every type of scanner, so the radiologist must confirm that any alternative will still provide appropriate images.
If you think you will struggle to remain still, contact the provider in advance. Movement can blur images and may mean part of the examination has to be repeated.
MRI safety still comes first
MRI uses a powerful magnetic field. Complete the safety questionnaire carefully and tell the team about implants, pacemakers, metal fragments, previous surgery, pregnancy or possible pregnancy and any other relevant medical history. Anxiety support must never bypass these safety checks.
If you cannot complete the MRI
Tell the radiographer if your anxiety becomes difficult to manage. The team can explain what options are available, although stopping may mean that the scan needs to be rearranged or another test considered. If the scan is clinically important, contact the referring doctor to discuss a plan rather than abandoning the investigation without advice.
What happens during an MRI appointment
An MRI uses a strong magnetic field and radio waves, not ionising X-rays, to create detailed images. You normally lie on a couch that moves into the scanner. The radiographer monitors you from an adjoining room and can communicate with you throughout. The scanner makes loud knocking or tapping sounds, so hearing protection is provided. Remaining still helps prevent blurred images, and some examinations include brief breath-holds.
The time in the scanner depends on the body area and sequences required. Tell the team before the examination if you have experienced panic in confined spaces, have pain that makes lying still difficult, or need help getting onto the couch. They can explain the procedure and discuss practical adjustments that are available at that service.
Practical ways to manage anxiety
Before the appointment, ask what the scanner looks like, how long the examination is expected to take, whether music or headphones are available and how you can alert the radiographer if you need help. Some people find slow breathing, closing their eyes before the couch moves, or focusing on a steady rhythm helpful. Agreeing a clear signal with the radiographer can make the experience feel more predictable.
Do not take sedatives or someone else’s medication to manage scan anxiety. If anxiety is severe, discuss this in advance with your doctor arranging the scan. Medication to help you relax may be appropriate for some people, but it requires planning, and you may need someone to take you home. Follow the specific instructions from your imaging provider.
When an MRI may need extra safety checks
Tell the imaging team about pacemakers, implanted devices, aneurysm clips, metal fragments, previous surgery, pregnancy or possible pregnancy, kidney problems and any previous reaction to contrast. Many implants are MRI-compatible under defined conditions, but the team needs the exact device details and may need to check the manufacturer’s conditions before scanning.
If you cannot complete an MRI despite support, do not assume that another scan is automatically equivalent. your doctor can consider whether the clinical question can be answered by another test, whether a modified MRI approach is available, or whether the scan should be rescheduled with a plan to manage anxiety.

Frequently asked questions
Answers to common questions about your scan, how to prepare and what happens next.
Can I ask for the MRI to stop?
Tell the radiographer if you are struggling. The team will explain how you can communicate during the scan and what can be done if you need a break.
Can I take medication for MRI anxiety?
Sometimes medication is considered, but it must be discussed with a suitable doctor in advance. It can affect driving and may require someone to accompany you.
Can I bring someone into the MRI room?
Policies and MRI safety rules vary. Ask the provider whether someone can accompany you to the department or, if safe and permitted, into the scan room.
Will an open MRI always be available?
No. Availability and suitability depend on the provider and the clinical question. A radiologist must ensure the examination can still answer the question properly.
