Safety of serial MRI in patients with implantable cardioverter defibrillators. Abstract The use of magnetic resonance imaging (MRI) is increasing globally, and MRI safety issues regarding medical devices, which are constantly being developed or upgraded, represent an ongoing challenge for MRI personnel. The remaining three MRI examinations were aborted because of the extent of image artifact and the futility of the examination to provide useful diagnostic information. At long-term follow-up (results of which were available for 63% of the patients), the most common notable changes from baseline were decreases in P-wave amplitude (in 4% of the patients), increases in atrial capture threshold (4%), increases in right ventricular capture threshold (4%), and increases in left ventricular capture threshold (3%). Pacing Clin Electrophysiol 2005;28:270-273, 8. In total, 96% (95% CI, 95 to 97) of all the MRIs were performed without the occurrence of either an event (e.g., power-on reset or early termination of the examination) or a notable change in lead setting immediately after the MRI. Journal homepage. Spine Journal 2013;13:815-22. A pre-MRI procedure screening process has been put in place to guard the safety of all individuals who enter the MR environment, aided by the use of a checklist; recent chest X-rays are checked for presence of a pacemaker for patients who are unable to give a clear history; & an additional screening step with the use of handheld ferromagnetic detection device has been instituted. Another examination was stopped as a result of frequent, nonsustained ventricular tachycardia in a patient who was undergoing MRI before undergoing catheter ablation of ventricular tachycardia. It requires evaluating objects with respect to “compatibility” - the potential for damage to the device & components, the malfunctioning of the device affected during the MR procedure, &/or the potential source of image artifacts.

Abstract The use of magnetic resonance imaging (MRI) is increasing globally, and MRI safety issues regarding medical devices, which are constantly being developed or upgraded, represent an ongoing challenge for MRI personnel. MRI safety can be divided into: In pacemakers without magnet-mode programming capability, reed switch activation by MRI led to transient, asymptomatic asynchronous pacing at the pacemaker-specific magnet rate (typically 85 pulses per minute) without any clinically significant symptoms or sequelae. Table S6 in the Supplementary Appendix summarizes changes in device parameters that can be expected to occur between two interrogations (up to 50% change from baseline) and notable changes (>50% change from baseline), as well as persistent versus new changes at long-term follow-up. they will attempt to line up with the field). Implantable cardiac defibrillator interactions with magnetic resonance imaging at 1.5 Tesla. Those creating and reviewing … D S Mujumdar, S M Ng, S Ang, ISQUA18-1404Is Your Patient MRI Safe? Magnetic Resonance Imaging (MRI) is the first international multidisciplinary journal encompassing physical, life, and clinical science investigations as they relate to the development and use of magnetic resonance imaging. Previous reports have also suggested that MRI of the thorax may present a greater risk of safety issues than MRI of nonthoracic regions owing to greater power deposition over the region containing the device.7,41 In our smaller study that was reported previously,14 we noted an association between thoracic imaging and changes in long-term right ventricular sensing and capture threshold. Five other MRI examinations were terminated prematurely. Importance Fetal safety of magnetic resonance imaging (MRI) during the first trimester of pregnancy or with gadolinium enhancement at any time of pregnancy is unknown.. The remaining five patients, all of whom had pacemakers, completed the examinations despite having transient events of power-on reset. Doctors ordering MRI scans are often unaware of the problems/implications of these implants & devices. Read the latest articles of Magnetic Resonance Imaging at ScienceDirect.com, Elsevier’s leading platform of peer-reviewed scholarly literature . Magnetic resonance imaging safety: implications for cardiovascular patients. It is vital, however, to emphasize the need for appropriate device programming, monitoring by qualified personnel, and the availability of an external pacing backup for such patients. Abstract Magnetic resonance (MR) imaging can provide critical diagnostic and anatomic information while avoiding the use of ionizing radiation, but it has a unique set of safety risks associated with its reliance on large static and changing magnetic fields, high-powered radiofrequency coil systems, and exogenous contrast agents. We evaluated the safety of MRI, performed with the use of a prespecified safety protocol, in 1509 patients who had a legacy pacemaker or a legacy implantable cardioverter–defibrillator system. Continuous variables are summarized as medians and interquartile ranges, and discrete variables as absolute numbers and percentages. J Am Coll Cardiol 2004;43:138A-138A.

Therefore, in pacing-dependent patients, the device may transiently cease pacing because of electromagnetic interference, and electrocardiographic monitoring and pulse oximetry are warranted so that the scanning can be stopped if inhibition of pacing occurs. Telephone follow-up conducted in September 2015 for the 551 patients in whom long-term interrogation results were unavailable revealed that 124 of the patients (23%) had died and 125 (23%) were alive and had no device-related problems. Chapter 5 MRI Zones. 3.7 CiteScore. Presently, MRI imaging of patients with neural implants is highly restricted in high field MRI (e.g., 3 T and higher) due to patient safety concerns. ); and the Departments of Medicine–Cardiology (S.N., R.H., A.A.R., V.W., D.M., E.G.I., A.K., R.D.B., H.C., A.C.L., H.R.H. The specific absorption rate of MRI sequences, a measure of power absorbed per mass of tissue, was limited to less than 2.0 watts per kilogram in the first 55 patients enrolled in the study.8 However, given the lack of association between the specific absorption rate and changes in device parameters5,33 and the unreliability of the specific absorption rate to guide MRI safety recommendations,34 no restrictions beyond standard specific absorption rate limits were applied in subsequently enrolled patients. they will be pulled towards the centre of the magnet) and a torque (i.e. The ISMRM publishes two journals, Magnetic Resonance in Medicine and Journal of Magnetic Resonance Imaging.
