Key result
MRI-conditional pacemakers allow patients to safely undergo MRI examinations when specific safety protocols and device programming are followed.
Why the study?
Pacemakers were previously an absolute contraindication to MRI, but newly developed MR-compatible devices have made MRI examinations possible in these patients.
Is MRI safe and feasible in patients with implanted MR-compatible pacemakers?
Is MRI safe and feasible in patients with implanted MR-compatible pacemakers?
The development and clinical introduction of MRI-compatible pacemakers have safely enabled MRI diagnostics for pacemaker-dependent patients when appropriate protocols are strictly followed.
Supports MRI consideration in conditional pacemaker patients under protocols; leaves open need for prospective validation across devices.
Purpose. Until recently, an implanted pacemaker was an absolute contraindication to MRI, regardless of the field of study. Patients with pacemakers couldn’t undergo MRI and get the diagnostic information. In recent years, new types of implantable devices that are compatible with MRI have been developed and introduced into clinical practice. This allowed MRI examinations for such patients, including cardiac studies. The review focused on the safety of MRI in patients with implanted MR-compatible pacemakers. The features of procedure, differences from the routine study are considered. The images quality and interpretability both in the implantation zone and in the area of the electrodes are discussed
