Background: Examining patients with cardiac pacemakers and implantable cardioverter-defibrillator systems (ICD) requires special cautions und preparations in order to assure patient safety.
Objectives: Is it possible for pacemaker and ICD patients to safely undergo MRI examination?
Materials and methods: This review provides information on interaction between the pacemaker and MRI systems, provides a review on the evidence published so far and describes how to perform a safe MRI examination in a patient with an implanted pacemaker device.
Conclusion: MRI in patients with cardiac pacemaker and ICD systems is safe under specified conditions and should be offered to patients with a given indication for a MRI.
