How do I prepare for an MRI for Lymphoma

Preparing for an MRI for Lymphoma

An MRI (magnetic resonance imaging) is an important imaging test that helps your oncology team see inside your body to evaluate your lymphoma. Here's what you need to know to prepare:

What to Expect During the Test

According to the NCCN Guidelines for Patients: Marginal Zone Lymphomas, an MRI uses radio waves and powerful magnets to take detailed pictures of the inside of your body—it doesn't use x-rays like a CT scan does. The test typically takes 30-60 minutes, and you'll be asked to hold your breath for 10-20 seconds at a time while the technician collects images.

Key Preparation Steps

Before Your Appointment:

• Tell your care team about any metal in your body — This is critical. MRI machines use very strong magnets, so you need to disclose:

  • Pacemakers or implanted devices
  • Metal pins, plates, or screws from surgery
  • Tattoos (some older tattoo inks contain metal)
  • Metallic eye makeup or eyeliner
  • Hearing aids or cochlear implants
  • Any other metal implants

• Wear comfortable, metal-free clothing — Remove jewelry, watches, belts with metal buckles, and any other metal accessories before entering the MRI room

• Arrive early — This gives you time to complete paperwork and ask questions

• Eat and drink normally — Unless your doctor tells you otherwise, you can eat and drink before your MRI

If Contrast Will Be Used: According to NCCN Guidelines, contrast material is often used during MRI to make the pictures clearer. This contrast helps enhance images of organs and structures in your body. The contrast is not permanent—it leaves your body in your urine immediately after the test.

• Tell your care team if you've had allergic reactions to contrast before — This is very important. If you have a serious allergy or if your kidneys aren't working well, your doctor may decide not to use contrast or may give you medicines to prevent allergic reactions

• Ask about kidney function — If you have kidney problems, mention this to your care team before the test

Managing Anxiety

If you have claustrophobia (fear of enclosed spaces), tell your care team ahead of time. According to NCCN Guidelines, closed MRIs (which surround you like a capsule) are more common than open MRIs, but your team may be able to arrange an open MRI if needed. Some facilities also offer:

• Sedation or anti-anxiety medication
• Headphones to listen to music during the scan
• A panic button you can press if you need to stop

Day of Your Appointment

• Arrive 15 minutes early
• Remove all metal items (glasses, hearing aids, dentures with metal, etc.)
• Use the restroom before entering the MRI room
• Let the technologist know if you feel anxious or uncomfortable
• Stay still during the scan—movement can blur the images
• Listen for instructions from the technologist through the intercom

After Your MRI

• You can return to normal activities immediately
• If contrast was used, drink extra water to help flush it from your body
• Your radiologist will review the images and send a report to your oncologist

Important Questions to Ask Your Care Team

1. Will contrast be used during my MRI, and do I need to do anything special to prepare?
2. How long will the test take, and when will I get the results?
3. Do I have any metal implants or conditions that might affect the MRI?
4. Can I bring someone with me for support?
5. What should I do if I feel anxious or claustrophobic during the scan?

Key Takeaway

While imaging reports might be available through your patient portal, the NCCN Guidelines recommend waiting to discuss these results with your care team. Your oncologist will interpret the findings in the context of your complete medical picture and lymphoma treatment plan.
