Many older pacemakers are unsafe to be scanned (and even some of the newer ones). The magnetic field can permanently damage some of their components such as reed switches.

Sometimes when a person has had a pacemaker removed, it’s not possible to remove the pacing wires. This can be for a variety of reasons but there is a risk that these wires can heat up during a MR scan. If you have had a pacemaker in the past, we will confirm that the pacing wires have been removed before your MR scan.
