An MRI scan is loud, narrow, and can last anywhere from 25 to 45 minutes or longer, which is more than enough time for anxiety to spiral. The good news: with the right preparation, most people get through it without sedation. About 2.3% of patients scheduled for an MRI experience claustrophobia severe enough to disrupt or cancel the scan, and among people who already have anxiety, that number jumps to 35%. Whether you have a diagnosed anxiety disorder or just feel uneasy in tight spaces, these strategies can make a real difference.
Know What You’re Walking Into
A standard MRI bore is about 60 centimeters (roughly 24 inches) across. That’s tight. Wide-bore machines open up to about 70 centimeters, and open MRI machines have no tube at all, using magnets above and below you instead. If space is your biggest concern, call the imaging center ahead of time and ask which type of machine they use. Many facilities now offer wide-bore scanners, and switching to one can be the single most effective thing you do.
The machine is also extremely loud. Gradient coils inside the scanner vibrate rapidly during imaging, producing mechanical knocking and buzzing that averages above 95 decibels on most scans and can spike past 105 decibels on higher-powered machines. That’s comparable to standing next to a running lawnmower. You’ll be given earplugs, headphones, or both. Use them. Knowing that the noise is normal, not a sign that something is wrong, helps your brain categorize it as background rather than threat.
Brain and spine scans typically take around 45 minutes. Joint scans (knee, ankle, wrist, hip) usually run 25 to 45 minutes. If your scan requires contrast dye, add about 15 minutes. Ask the technologist before you go in how long your specific scan will take, then mentally break that time into smaller blocks. Forty-five minutes is daunting. Nine five-minute segments is manageable.
Breathing Techniques That Work in the Scanner
Controlled breathing is the most accessible tool you have because it requires no equipment and you can do it lying perfectly still. The simplest version: inhale slowly through your nose for four counts, hold for four counts, exhale through your mouth for six counts. The longer exhale activates your body’s relaxation response by stimulating the vagus nerve, which slows your heart rate and lowers blood pressure. Practice this at home before your appointment so it feels automatic when you need it.
A more structured approach borrows from mindfulness-based stress reduction. Instead of just counting breaths, focus your attention on the physical sensation of air entering your nostrils, filling your chest, and leaving your body. When your mind drifts to the walls of the scanner or how much time is left, notice that thought without judgment and bring your attention back to the breath. This isn’t about achieving some zen state. It’s about giving your brain a task that competes with anxious thoughts. A randomized controlled trial found that patients who used mindfulness-based breathing during MRI scans reported significantly less claustrophobic distress than those who didn’t.
Use the Sensory Tools Available to You
Most imaging centers offer more comfort options than people realize, but you often have to ask. Prism glasses are angled lenses that let you see out of the scanner bore while lying flat on your back. Instead of staring at a wall six inches from your face, you get a view of the room, the technologist’s window, or a screen playing video. This simple shift in visual perspective reduces the closed-in feeling dramatically. The glasses are lightweight, fit most face shapes, and are safe in scanners up to 3 Tesla.
Many facilities also pipe music or audio through MRI-compatible headphones. Bring a playlist or podcast suggestion. Familiar audio gives your brain something to track, which occupies the same mental bandwidth that would otherwise fuel anxiety. Some centers even offer video goggles with movies or nature scenes. Call ahead and ask what’s available so you’re not discovering options (or the lack of them) while already on the table.
A warm blanket can also help. It sounds minor, but MRI rooms are kept cold to protect the equipment, and being physically uncomfortable adds to the sense that something is wrong. A blanket creates a layer of comfort that subtly signals safety to your nervous system.
Stay Connected to the Technologist
You are never locked inside an MRI machine. You will be given a squeeze bulb to hold during the entire scan. Pressing it triggers a loud alarm at the technologist’s workstation, and they will respond immediately. In most setups, there’s also a two-way intercom so you can talk to the technologist and hear them between scan sequences.
Before the scan starts, ask the technologist to check in with you periodically and to tell you how much time is left at each break between sequences. MRI scans aren’t one continuous block. They’re a series of shorter sequences, each lasting a few minutes, with brief pauses in between. Those pauses are natural checkpoints. Knowing you’ll hear a voice every few minutes makes the experience feel less isolating. Some people also find it helpful to ask the technologist to count down: “This next one is four minutes” gives you a finish line to focus on.
Prepare Your Body the Day Before
Skip caffeine on the morning of your scan. Caffeine raises your baseline heart rate and primes your nervous system for a fight-or-flight response, which is exactly what you’re trying to avoid. If you’re a heavy coffee drinker, taper rather than going cold turkey so you don’t add a withdrawal headache to the mix.
Sleep matters more than you might expect. A night of poor sleep lowers your threshold for stress and makes it harder to use coping strategies effectively. If you tend to sleep poorly before stressful events, consider doing a relaxation exercise before bed the night before: progressive muscle relaxation (tensing and releasing each muscle group from toes to forehead) takes about 10 minutes and can improve both sleep quality and next-day anxiety.
Wear comfortable clothes without metal. Zippers, underwire bras, and belt buckles will need to be removed, and changing into a hospital gown adds an extra layer of unfamiliarity. Sweatpants and a cotton t-shirt let you stay in your own clothes, which preserves a small but real sense of normalcy.
Going Feet-First and Keeping Your Eyes Closed
For scans of the knee, ankle, hip, or lower spine, you may be positioned feet-first in the scanner. This means your head stays near the opening or even outside the bore entirely. If your scan allows it, ask whether feet-first positioning is an option. It removes the most claustrophobia-triggering element: having your face inside the tube.
For head-first scans, closing your eyes before you’re moved into the bore and keeping them closed throughout is one of the most commonly recommended strategies. If you never see how close the walls are, your brain has much less spatial information to panic about. Pair closed eyes with your breathing technique and audio, and you’ve essentially built a cocoon of distraction.
Some people prefer a sleep mask or a washcloth draped over their eyes. This removes the temptation to peek and adds a gentle pressure that some find calming. Ask if the facility can provide one, or bring your own (make sure it has no metal components).
When You Need More Than Coping Strategies
If you’ve tried an MRI before and couldn’t finish, or if your anxiety is severe enough that breathing exercises alone won’t cut it, sedation is a legitimate option. Mild oral sedation, typically a short-acting anti-anxiety medication, is the most common approach for adults. You’ll take it 30 to 60 minutes before your scan, and you’ll need someone to drive you home afterward. Let your doctor know about your anxiety when the scan is ordered, not on the day of the appointment. This gives them time to prescribe medication and allows the imaging center to schedule extra time for your visit.
For people whose claustrophobia is a recurring problem, not just an MRI issue, a few sessions of cognitive behavioral therapy focused on enclosed spaces can reduce anxiety enough to make scans manageable without medication. This isn’t a quick fix for next Tuesday’s appointment, but it’s worth considering if you anticipate needing MRIs in the future.
