Key result
Cardiac magnetic resonance imaging in patients with implantable loop recorders produced significant, uninterpretable hyperintensity artifacts, despite no changes in device parameters at 3 months.
Why the study?
Does cardiac MRI produce interpretable images and maintain device function in patients with implantable loop recorders?
Case Report (n=2)
Does cardiac MRI produce interpretable images and maintain device function in patients with implantable loop recorders?
While cardiac MRI is safe for patients with implantable loop recorders, the devices cause significant hyperintensity artifacts that can render the images uninterpretable.
No takes yet. Share an insight, caveat, or question.
ILR artifacts may render cardiac MRI uninterpretable despite preserved device function; leaves open clinical utility pending larger studies.
Blaschke et al. (2015) conducted a case report in Patients with an Implantable Loop Recorder (n=2). Cardiac Magnetic Resonance Imaging was evaluated on Cardiac MRI image quality and ILR device parameters. Cardiac magnetic resonance imaging in patients with implantable loop recorders produced significant, uninterpretable hyperintensity artifacts, despite no changes in device parameters at 3 months.
