WebJul 5, 2024 · Pacemakers cause metallic susceptibility artefacts due to distortion of the magnetic field [ 15 ]. There are limited data about patients with LCP undergoing CMR imaging [ 16 ]. To the best of our knowledge, there are no prospective studies in the literature about artefacts on CMR imaging in patients with implanted LCP. WebHowever, it has been estimated that a patient with a pacemaker will have a 50–75% probability of being indicated for an MRI study over the lifetime of the device . The aim of this review is to evaluate the literature on patients with pacemakers who underwent MRI examinations to determine its safety and help define a consensus statement.
