The first task is to consult with the requesting physician and pacemaker patient to ensure that there is no appropriate diagnostic alternative to MRI. The device numbers and configuration, as well as the absence of abandoned leads will need to be confirmed. The statistics provide a strong argument for MRI conditional devices. absolute contraindication to MR scanning. Address correspondence to P. M. Colletti ([email protected]edu). For imaging of the lower thoracic and lumbar spine, pelvis, and lower extremity, the patient enters feet first with the magnet isocenter positioned superior to the T12 vertebra. Since the first regulatory approvals in 2008, MR Conditional pacemaker systems have been offered by cardiac device manufacturers. These examinations must be attended by radiology health care professionals with training for the use of the pacemaker system. We will also report on our own experience with these patients.
By choosing to accept, you acknowledge that you are a Certified Healthcare Professional. Radiologists should be knowledgeable of the specific limitations with regard to patient isocenter and coil positioning within the required 1.5-T MR system and the importance that the pacer be programmed before and after scanning. On completion of the MRI examination, the pacemaker professional resets the pulse generator to the SureScan “off” mode and reexamines the pacemaker to confirm normal function. In 2008, the first MR imaging–conditional device was released in the European market with subsequent release of a similar pacemaker in the United States in 2011. F. G. Shellock is a consultant for Medtronic, Boston Scientific, and St. Jude Medical. The patient is prepared for the MRI procedure, which includes utilizing appropriate monitoring techniques (e.g., MR-conditional monitors may include pulse oximetry, ECG, and other appropriate means of performing physiologic monitoring) before the patient enters the 1.5-T MR system. “I’d never thought my pacemaker could prevent me from getting an MRI,” Alan says. The safe use of this new device technology will require conscientious system-based care delivered by requesting physicians, cardiologists, MRI managers, MRI technologists, and radiologists.

Reprogramming should occur immediately after scanning while the patient is still on a cardiac monitor. As a result, an MRI was not usually considered for patients with a pacemaker. It is intended to assist healthcare professionals in determining if an implanted system is MR Conditional. Patients with pacemakers – even if they are MRI-conditional – must alert their medical team about their devices prior to an MR-guided test or screening. Home The historic concern of scanning a patient with a pacemaker was indeed a legitimate safety concern, he adds “I think the first thing to keep in mind is these devices are designed to be MRI conditional. In addition, power-on-reset events can occur occasionally (0.7-3.5% rate) in non-MRI conditional devices, especially older devices, which can be life-threatening in pacemaker-dependent patients. However, it continues not to reimburse for MRIs performed in patients with other pacemaker systems.
Before the patient enters the MR system, a health care professional with cardiology Revo SureScan training will reexamine the pacemaker and if the specifications described are achieved, the pacer is set to the SureScan “on” mode . This will likely be detailed in the information you received when you had it placed. The recent approval of an “MR-conditional” pacemaker system by the U.S. Food and Drug Administration allows patients with that pacemaker system to undergo MRI examinations within specific conditions. Since then, physicians such as Dr. Vikas Kuriachan, cardiologist and cardiac electrophysiologist at the Libin Cardiovascular Institute of Alberta, and University of Calgary are faced with deciding which patients are the more likely candidates for an MRI conditional pacemaker or implantable defibrillator.
