Confirm the exact exam first
Preparation instructions can differ by body area, use of contrast, medication, sedation, and facility policy. Ask for the name of the exam and the instructions that apply to it.
Do not assume that instructions from a prior MRI or another facility still apply.
Confirm:
- the body area and exam name;
- whether the exam uses contrast;
- expected scan and visit time;
- arrival time;
- food and drink instructions;
- medication instructions;
- clothing rules;
- records or images to bring;
- payment due; and
- transportation needs.
If a provider ordered the MRI, make sure the imaging center has the order before the appointment.
Complete the safety check early
Tell the imaging center about implants, devices, prior surgery, metal exposure, pregnancy, patches, tattoos, kidney disease, contrast reactions, and any other item on its safety form.
Bring an implant or device card when you have one. The team may need the manufacturer, model, and conditions for safe use.
Call before the appointment if the identity of a device is uncertain. Do not wait until you are changing for the scan.
Follow the food and medication instructions you receive
Many MRI exams allow normal food and medication. Some exams, contrast plans, or sedation plans require different instructions.
Use the directions from the imaging center and the clinician responsible for your medication. Do not stop a prescribed medication because of a general article.
If you use a medication patch, insulin pump, glucose monitor, or another attached device, ask what to do before you arrive. MRI safety depends on the exact product.
Choose simple clothing
The facility may ask you to change into approved clothing. This reduces the chance that hidden metal, metallic fibers, fasteners, or pockets enter the scanner room.
Leave jewelry and unneeded valuables at home. Be ready to remove:
- watch and jewelry;
- phone and wallet;
- keys and coins;
- hairpins and clips;
- hearing aids;
- removable dental items;
- glasses;
- piercings when the team directs;
- clothing with zippers, snaps, hooks, or metallic fibers; and
- any other item identified during screening.
Ask about makeup, nail products, hair products, or tattoos if you have a concern. Some products can contain material that affects safety or image quality.
Know what the scanner feels and sounds like
You will lie on a table that moves into the scanner. The body area being imaged and the scanner design determine how far you enter.
The scanner makes loud tapping, knocking, and thumping sounds while images are recorded. Those sounds are normal. You should receive hearing protection.
The technologist can see, hear, and speak with you. Ask where the call device is and how to use it. Confirm whether you can listen to music.
You will need to remain still during image sequences. Some scans include breath-hold instructions. Ask the technologist to explain the sequence before it begins.
Tell the team about claustrophobia before the appointment
Claustrophobia is common and worth planning for. Tell the imaging center how confined spaces have affected you in the past and whether you have completed an MRI before.
Ask which options fit your exam:
- a wider scanner opening;
- a mirror or visual aid;
- music or headphones;
- regular communication;
- a short pause between sequences;
- a support person who passes MRI safety screening;
- a practice visit or scanner explanation; or
- medication prescribed by a clinician.
Not every option works for every exam. A more open scanner may not perform every protocol.
Practice a simple plan for the scan
Before the table moves, agree on:
- how the technologist will describe the next sequence;
- how long the first sequence will last;
- how you will signal a problem;
- what can pause safely;
- what hearing protection you will use; and
- whether music or another approved comfort option is available.
During the scan, keep your attention on the technologist's instructions and your breathing. Tell the technologist at once about pain, burning, unusual heat, dizziness, trouble breathing, or severe distress.
Do not try to leave the scanner without telling the technologist unless there is an immediate reason you cannot communicate.
Plan for pain or trouble staying still
Tell the team if pain, tremor, coughing, breathing limits, or another condition may make it hard to hold a position.
The team may adjust supports or sequence order when the protocol allows. Bringing the issue up early gives them more options.
Do not take extra pain or anxiety medicine unless the prescribing clinician has told you how to use it for this exam.
If medication or sedation is planned
Confirm:
- who prescribes it;
- when to take it;
- food and drink limits;
- whether monitoring is needed;
- whether an adult must accompany you;
- whether you can drive;
- how long you should avoid work or decisions; and
- who to call with a reaction or concern.
Medication and sedation have risks beyond MRI itself. Follow the written plan.
What to bring
- photo identification;
- the order, when required;
- insurance or payment information requested by the office;
- implant and device records;
- a medication list when requested;
- relevant prior imaging or information on where to obtain it;
- written preparation instructions; and
- the name of the clinician who should receive the report.
Do not bring medical records through a general website contact form. Use the secure path named by the imaging center.
Before you leave
Ask:
- when the final radiology report is usually available;
- who receives it;
- how you can obtain a copy;
- who will discuss the result;
- what to do if you have not heard by the stated time; and
- which symptoms should receive prompt care instead of waiting for the report.
A clear result plan is part of preparation. It prevents uncertainty after the scan.
