Getting an MRI: How to Prepare & What to Expect

If the idea of being slid into a loud, narrow tube makes your chest tighten, you’re in good company. Nearly 10% of MRI patients experience claustrophobia or anxiety during an MRI scan, and some people feel it even if they never thought of themselves as claustrophobic before. A lot of that fear comes from not knowing what’s about to happen. 

An MRI uses a powerful magnet and radio waves to create detailed pictures of what’s happening inside your body, which is why providers often order it to help diagnose conditions like ongoing pain, sports injuries, neurological symptoms, or when a clearer view than an X-ray can provide is needed. While MRIs are painless, the experience can catch some people off guard if not prepared. 

Continue reading to learn how an MRI works, what happens during an MRI scan, and where to find the best imaging center in Chino Hills for brain, joint, or spine MRIs.

How Does an MRI Work?

An MRI uses a strong magnet and radio waves to produce images from the inside, unlike the ionizing radiation used in X-rays or CT scans. For an MRI, you lie on a table that slides into the scanner, and a computer converts the radio wave signals into detailed images of soft tissues such as the brain, spinal nerves, discs, ligaments, and cartilage. An MRI is commonly recommended to take a closer look at the brain, spinal cord, abdomen, joints, and extremities. 

During the procedure, you’ll hear loud knocking or thumping noises as the MRI machine works. The most important thing you can do is stay still so the images don’t blur. If you’re anxious about the confined space or the noise, the staff can help make your scan more manageable with various techniques, including noise-cancelling headphones and anti-anxiety medication.

How to prepare for an MRI

Preparing for an MRI is simpler than most people expect, which can be a relief when your nerves are already buzzing. For most MRI scans, you can eat and drink normally and take your regular medications unless your appointment instructions tell you not to. When you arrive, you will likely fill out a safety screening form that asks detailed questions about any metal, implants, or medical devices inside your body. This matters because the MRI magnet is strong enough to pull on hidden metal. You should plan to arrive a little early, as you may need extra time to change into a gown, store your belongings, finish paperwork, or have an IV placed if your MRI scan uses contrast. 

What to Expect During an MRI

An MRI appointment is less anxiety-provoking when you know what to expect: 

• When you arrive for an MRI, you’ll first meet with the MRI technologist, who will go through the intake questions and confirm the type of MRI you are there to get. 
• You’ll then be asked to remove metal items, such as jewelry, watches, an underwire bra, and hair clips. 
• You may be asked to change into a hospital gown, depending on the type of MRI you’re getting.
• If your MRI includes contrast, the technician will establish an intravenous line before your imaging study begins. 
• The MRI technician will help you lie on a padded table that slides into the scanner and properly position you with cushions or straps so you can stay comfortable and still during the imaging study. 
• You may get earplugs or headphones to soften the noise and help you relax and pass the time. 
• Once the scan starts, you’ll hear a mix of rhythmic knocking and buzzing, and you may feel the table vibrate slightly as the machine works. 
• Most scans take about 30 to 60 minutes, and if contrast is needed, it’s usually given through a small IV partway through the scan.

It’s important to know that you will not be alone, even if you cannot see your technician. However, you’ll be able to speak to them at any time during the scan via an intercom.

What Should I Wear During an MRI? 

The safest choice is comfortable clothing with no zippers, snaps, or fasteners. Many times, you’ll be asked to change into a gown anyway. Jewelry, watches, hairpins, glasses, hearing aids, and underwire bras must be removed before your scan begins. You’ll be able to lock your phone, wallet, keys, jewelry, and anything else you have with you in a locker before your scan. Some cosmetics contain tiny metal particles, so it’s best to go to your imaging study with a fresh face. 

MRI Safety: What to Know About Implants, Pacemakers, Metal Fragments, Tattoos, and Pregnancy

Some medical implants and devices, including certain pacemakers, neurostimulators, and implanted pumps, can react to magnets or require special scanning protocols, which is why it is important to disclose everything about your past medical history. 

Some tattoo pigments can warm slightly during the scan, but this is usually not a contradiction for getting the scan. Body piercings must be removed before the scan because they contain metal. Getting an MRI while pregnant is usually considered safe in all trimesters. But you’ll still want to mention your pregnancy since you may need different positioning for comfort. 

Calming Claustrophobia and Anxiety During an MRI

It’s common to feel anxious about getting an MRI, especially when you are already in pain, or you know tight spaces make you feel panicked. The best way to ensure you have a good experience is to tell the staff what you are worried about before getting on the table, because there are options that can make the scan easier: 

• A wide-bore MRI can give you more room around your shoulders and face
• Short breaks between scan sequences can help you reset
• Positioning supports like cushions and pads can take pressure off sore joints and help you hold still without fighting discomfort
• Mild sedation may be an option if you’re feeling particularly nervous, though this may require fasting, and you will need someone to drive you home
• Noise-cancelling headphones or earplugs can help you relax and pass the time with a good audiobook, podcast, or music
