Each issue features 15-20 articles focused on a variety of radiologic subspecialties, including imaging physics, informatics, and diagnostic imaging. Although generally considered safe, magnetic resonance imaging (MRI) has a number of safety issues, including the effects of high magnetic fields and radiofrequency pulses on the body, and on implanted devices, the side effects of contrast agents, toxicity during pregnancy, claustrophobia, and hearing loss. The FRED for treatment of difficult-to-treat or otherwise untreatable intracranial aneurysms was prospectively observed in this clinical study to provide a high degree of safety and efficacy, measured as complete aneurysm occlusion on DSA and MR imaging during 6-month follow-up. Metallic implants potentially pose hazards or problems for patients referred to magnetic resonance imaging ... American Journal of Neuroradiology. The MRI was aborted and programming was restored; there were no clinical sequelae. During events of power-on reset, the device is susceptible to inhibition of pacing output and activation of antitachycardia therapies.39,40 Of the 9 MRI examinations in which events of power-on reset occurred, 1 examination was associated with mild physical symptoms, 1 (which occurred near the end of the battery life of the device) resulted in an inability to reprogram the device and in the consequent replacement of the device, and 1 was associated with transient inhibition of pacing. Sharif MN, Wyse DG, Rothschild JM, Gillis AM. 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%).

MRI safety can be divided into: Historically, MRIwas contraindicated in patients with cardiovascular implantable electronic devices because the devices' metallic components made this imaging study unsafe. Examples provided are primarily referenced to neuroradiology reflecting the subspecialty for which MR currently has the greatest clinical application. Read the latest articles of Magnetic Resonance Imaging at ScienceDirect.com, Elsevier’s leading platform of peer-reviewed scholarly literature . In contrast, the change in long-term P-wave amplitude was significantly greater among patients with pacemakers than among patients with ICDs. 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. No long-term clinically significant adverse events were reported. Candidates who had an ICD or a pacemaker and a clinical indication for MRI were referred by primary care and subspecialty physicians and were enrolled during the period from February 2003 through January 2015. The institutional review board at Johns Hopkins University approved the protocol, which is available with the full text of this article at NEJM.org.

Device parameters, which were assessed immediately after the MRI in all the patients and at long-term follow-up in patients who returned for reassessment, included P-wave amplitude; right ventricular and left ventricular R-wave amplitude; atrial, left ventricular, and right ventricular lead impedance; atrial, right ventricular, and left ventricular capture threshold; and battery voltage. Tetiana Glushko, Lulu He, William McNamee, Aparna S. Babu, Scott A. Simpson. D S Mujumdar, S M Ng, S Ang, ISQUA18-1404Is Your Patient MRI Safe? First, the data were acquired at a single center and may not be generalizable to other clinical settings and MRI facilities. Cohen JD, Costa HS, Russo RJ. Circulation 2006;114:1285-1292, 10. 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. The number of comparisons for each device parameter is unique, primarily because of variability in several factors, including the number of leads, the presence or absence of intrinsic P or R waves, the presence or absence of atrial arrhythmia, and pulse widths during the measurement of capture threshold at the follow-up interrogation. The first of these events was transient. MRI scanners, although free from potentially cancer-inducing ionizing radiation found in plain radiography and CT, have a host of safety issues which must be taken very seriously. The associations between changes in device parameters that occurred either immediately after the MRI or at long-term follow-up and the number of repeat scans, lead length, type of device, and anatomical region of imaging were assessed with the use of the nonparametric k-sample test on the median (unordered groups) or a nonparametric test for trend (ordered groups).
