CMRI in Patients with Cardiac Implanted Electronic Devices¹

The population of patients with different Cardiac Implanted Electronic Devices (CIEDs)¹ is growing. Because CIED patients with electrical abnormalities often have underlying structural heart disease, the indications for CMR examinations are expanding in this patient population. With the advent of MR-conditional CIEDs and the establishment of appropriate safety protocols the number of these exams is growing. However, device- and lead-related artifacts can limit image interpretability and the clinical applicability of CMR in CIED patients, especially in the case of ICDs and cardiac resynchronization therapy pacemakers or defibrillators.
A high-bandwidth inversion recovery sequence uses wideband techniques to reduce susceptibility artifacts.

This extends the benefit of tissue characterization to device patients, enabling them to receive diagnostically robust imaging that visualizes myocardial injury.
