Magnetic resonance myocardial imaging in patients with implantable
cardiac devices: challenges, techniques, and clinical applications
Abstract
Cardiovascular magnetic resonance imaging (MRI) in patients with cardiac
implants, such as pacemakers and defibrillators, has gained importance
in recent years with the development of modern cardiac implantable
electronic devices. The increasing clinical need to perform MRI
examinations in patients with cardiac implants has driven the
development of new advanced MRI sequences to mitigate image artifacts
associated with cardiac implants. More specifically, advances in imaging
techniques, such as wideband late gadolinium enhancement imaging,
wideband T1 mapping, and wideband perfusion, have been designed to
improve image quality and examinations in patients with cardiac
implants, enabling a comprehensive and more reliable diagnosis, which
was previously unattainable in these patients. This review article
explores recent developments and applications of wideband techniques in
the field of cardiovascular MRI, offering insights into their
transformative potential. Clinical applications of wideband
cardiovascular MRI are highlighted, particularly in assessing myocardial
viability, guiding ventricular tachycardia ablation, and characterizing
myocardial tissue.
