MRI with a Pacemaker or ICD

Can you have an MRI with a heart device? For most modern devices, yes — with the right precautions. Here's how MRI-conditional devices work and what to arrange beforehand.

“Can I still get an MRI?” is one of the most common questions after a device implant. For most people today, the answer is yes — with some planning.

What “MRI-conditional” means

An MRI uses a powerful magnetic field, which can interfere with a heart device. A device labeled MRI-conditional has been designed and tested to be safe in the scanner as long as a specific protocol is followed. Most pacemakers and ICDs implanted in recent years are MRI-conditional.

Two things matter:

  • The generator (the device itself) must be MRI-conditional, and
  • The leads (the wires) must be too. An older lead with a newer generator — or a mixed system from different implants — may not qualify.

Your device ID card lists whether your system is MRI-conditional. We can also confirm it from your records.

What has to happen for the scan

  • The MRI center must follow the manufacturer’s specific settings and conditions.
  • The device is usually reprogrammed just before the scan (so the magnetic field isn’t misread) and set back to normal afterward — done by a trained device technician.
  • You’ll be monitored during the scan.

This is routine at centers that do it regularly — it just needs to be arranged in advance.

If your device isn’t MRI-conditional

Sometimes a scan is still possible at experienced centers under a careful protocol, and sometimes an alternative test (CT, ultrasound) answers the question instead. We’ll help weigh the options with the doctor who ordered the scan.

Before you schedule

  1. Tell the ordering doctor and the MRI facility that you have a pacemaker or ICD.
  2. Bring your device ID card.
  3. Check with our office first — we’ll confirm your system is MRI-conditional and coordinate the reprogramming.
