IV-qualified MR technologists may administer FDA-approved gadolinium-based MR contrast agents via peripheral intravenous routes as a bolus or slow or continuous injection, as directed by the orders of a duly licensed site physician. Patients who require EKG monitoring and who are, unconscious, sedated, and/or anesthetized should be examined with potential repositioning, after each imaging sequence, of the EKG leads and any other electrically conductive material with which the patient is in contact. For electrically conductive material, wires, leads, implants, etc., that are required to be within the bore of the MR scanner with the patient during imaging, care should be taken to place thermal insulation (including air, pads, etc.) HAVING SAFELY UNDERGONE A PRIOR MR EXAMINATION (WITH AN ANEURYSM CLIP—OR OTHER IMPLANT—IN PLACE) AT ANY GIVEN STATIC MAGNETIC FIELD STRENGTH IS NOT IN AND OF ITSELF SUFFICIENT EVIDENCE OF ITS MR SAFETY OR COMPATIBILITY, AND SHOULD NOT BE SOLELY RELIED UPON TO DETERMINE THE MR SAFETY OR COMPATIBILITY STATUS OF THAT ANEURYSM CLIP (OR OTHER IMPLANT). The document restates existing practices and articulates new ones. As noted in section B.2.m above, it is especially important to ensure that all police/fire response personnel are restricted from entering the MR scan room with their equipment (axes, air canisters, guns, etc.) Hardbound MRI Textbook. Pregnant health care practitioners are permitted to work in and around the MR environment throughout all stages of their pregnancy [10]. The level of compliance by staff will be assessed and documented annually. Recently added item(s) × You have no items in your shopping cart. ALL PRIORITIES SHOULD BE FOCUSED ON STABILIZING (E.G., BASIC LIFE SUPPORT WITH CARDIAC COMPRESSIONS AND MANUAL VENTILATION) AND THEN EVACUATING THE PATIENT AS RAPIDLY AND SAFELY AS POSSIBLE FROM THE MAGNETIC ENVIRONMENT THAT MIGHT RESTRICT SAFE RESUSCITATIVE EFFORTS. Send feedback. The physician responsible for MR safety, known as the magnetic resonance medical director (MRMD), is required to ensure continued appropriate evaluation and screening of patients, implants or devices, and equipment (eg, patient support equipment and surgical, radiation, and anesthesia devices) that are brought into the MR environment. Access to the MR scanner would then be based on that opinion. Decisions based on published MR compatibility or safety claims should recognize that all such claims apply to specifically tested static field and static gradient field strengths. As part of the Zone IV site restriction, all MR installations should be installed in such a way as to provide for direct visual observation by Level II MR Personnel to access pathways into Zone IV regions. Pregnant patients can be accepted to undergo MR scans at any stage of pregnancy if, in the determination of a Level Two MR Personnel-designated attending radiologist, the risk-benefit ratio to the patient warrants that the study be performed. Types of patients needing extra caution: Patients with implanted or retained wires in anatomically and/or functionally sensitive areas (e.g., myocardium or epicardium, implanted electrodes in the brain) should be considered at higher risk especially from faster MR imaging sequences, such as echoplanar imaging (which may be used in such sequences as diffusion weighted imaging, functional imaging, perfusion weighted imaging, MR angiographic imaging, etc.). References 1. The force of the device's 10-ton magnet is about 30,000 times as powerful as Earth's magnetic field, … The MRI Safety Guideline is intended to assist The Royal Australian and New Zealand College of Radiologists® (RANZCR) its staff, Fellows, members and other individuals involved in the Magnetic Resonance imaging team (radiographers, technologists and scientists) in addressing MRI safety issues and requirements. ACR Guidance Document for Safe MR Practices: 2013 . AJR Am J Roentgenol. For superconducting systems, in the event of a system quench it is imperative that all personnel/patients be evacuated from the MR scan room as quickly as safely feasible and the site access be immediately restricted to all individuals until the arrival of the MR equipment service personnel. Updated link to ACR Manual on MR Safety: 5-27-2020: Removed broken link to ACR Manual on MR Safety: Previous: QC: MRI: Next: Clinical Image Testing: MRI: Did you find it helpful? American College of Radiology White Paper on MR Safety, A. At least one of these individuals should be one of the Level Two MR Personnel of the MR site. Opportunities for improvement were highlighted during the audit and she is working to further align their policies and procedures with the latest ACR guidance. Patients with asthma also seem to be more likely to have an adverse reaction to gadolinium. There are potential risks in the MR environment, not only for the patient but also for the accompanying family members, attending health care professionals, and others who find themselves only occasionally or rarely in the magnetic fields of MR scanners, such as security or housekeeping personnel, firefighters, police, etc. I have read and understand the entire content of this form. Three preventions for each of the two top categories of MRI-equipment patient injury (burns and projectiles) were taken from the ACR Guidance Document on MR Safe Practices (2013). One of the very first statements in the ACR document is that facilities are to appoint an MR safety officer, an individual to take charge of safety issues at that site. Safety Guidelines for Magnetic Resonance Imaging Equipment in Clinical Use 5/85 1 Introduction 1.1 Background This is the 4th edition of the safety guidelines and aims to provide relevant safety information for users of magnetic resonance imaging (MRI) equipment in clinical use but will have some relevance in academic If no such forces are observed, a green label is to be affixed to the device/object prior to its introduction into Zone IV. First, it offers a set of refinements to sections of the previously published ACR Guidance Documents on MR Safe Practice. For guidance, see the ACR’s Manual on MR Safety and the ACR Manual on Contrast Media. These policies and procedures should also be reviewed concomitant with the introduction of any significant changes in safety parameters in the MR imaging environment of the site's MR service (e.g., adding faster/stronger gradient capabilities, higher RF duty cycle studies, etc.) MR Safety. In 2001, the American College of Radiology (ACR) formed a Blue-Ribbon Panel on Magnetic Resonance (MR) Safety in response to various reports in the medical literature and print media detailing MR imaging (MRI) adverse events and incidents involving patients, equipment, and personnel. This will help to serve as a heat sink for any focal power deposition that may occur, thus decreasing the likelihood of a clinically significant thermal injury/burn to adjacent tissue. Prior contrast agent reaction issues [18]: Adverse events after intravenous injection of gadolinium seem to be more common in patients who had previous reactions to an MR contrast agent. It is understood that the Medical Director of the MR site will be one whose education and experience in MR safety qualifies them for designation as Level Two MR Personnel. ACR Guidance Document on MR Safe Practices: 2013 Expert Panel on MR Safety: Emanuel Kanal, MD,1* A. James Barkovich, MD,2 ... and health care personnel safety for all MRI settings, including those designed for clinical diagnos-tic imaging, research, interventional, and intraopera- tive MR applications. Screening of all unconscious/unresponsive patients and/or patients who cannot provide their own reliable histories, or when the history cannot be reliably obtained from others, regarding prior possible exposures to surgery, trauma, and/or metallic foreign object history/exposure, in whom an MR examination is deemed clinically indicated/necessary: If no reliable patient metal exposure history can be otherwise obtained and if the requested MR examination cannot reasonably wait until such a time that a reliable such history might be obtained, it is recommended that such patients be physically examined by Level Two MR Personnel. MRI BIOEFFECTS, SAFETY, AND PATIENT MANAGEMENT is a comprehensive, authoritative textbook on the health and safety concerns of MRI technology that contains contributions from more than forty internationally respected experts in the field. All implanted intracranial aneurysm clips that are documented in writing to be composed of titanium (either the commercially pure and/or the titanium alloy types) can be accepted for scanning without any other testing necessary. At this time, the phantom can be purchased by MRI facilities that apply for accreditation, MRI equipment manufacturers, and consulting physicists or MR scientists only. The results of such testing as well as the date, time, and name of tester, and methodology used for that particular device should be documented in writing. (2) Guidelines for Screening Patients For MR Procedures and Individuals for the MR Environment, Institute for Magnetic Resonance Safety, Education, and Research, www.imrser.org. These variables may well have not resulted in adverse event in one circumstance but may result in significant injury or death on a subsequent exposure. At present there are no well-defined policies for patients who are considered to be at increased risk for having adverse reaction to MR contrast agents; however, the following recommendations are suggested: patients who have previously reacted to one MR agent can be injected with another agent, if they are restudied, and at-risk patients can be pre-medicated with corticosteroids and, occasionally, antihistamines [18]. They should only be brought into Zone III regions if they are under the direct supervision of specifically designated either Level One or Level Two MR Personnel who are thoroughly familiar with the device, its function, and the reason supporting its introduction into the Zone III designated region. The ACR has re-formed the MRI safety committee and we will likely see an updated 2018 version of the ACR Guidance Document as a result. The MRI Safety Guideline is intended to assist The Royal Australian and New Zealand College of Radiologists® (RANZCR) its staff, Fellows, members and other individuals involved in the Magnetic Resonance imaging team (radiographers, technologists and scientists) in addressing MRI safety issues and requirements. 1194 0 obj <>/Filter/FlateDecode/ID[<20AEACD81983814F8C8D73A1682A0C12><09E1D8F0DB9E644581B9DBEAF7695B7F>]/Index[1182 22]/Info 1181 0 R/Length 74/Prev 573332/Root 1183 0 R/Size 1204/Type/XRef/W[1 2 1]>>stream Specifically, this includes hospital/site administration, physician, security, and other non-MR Personnel (see section 2b, below).

Family/guardians of non-responsive patients or of patients who cannot reliably provide their own medical histories are to complete a written MR safety screening questionnaire prior to their introduction into Zone III regions. and updated as needed. Accreditation application and evaluation are typically completed within 90 days. All areas freely accessible to the general public without supervision. This is especially so if cryogenic gases are observed to have vented partially or completely into the scan room itself, as evidenced in part by the sudden appearance of white “clouds” or “fog” around or above the MR scanner. Clips manufactured prior to 1995 require either pre-testing (as per the ASTM Deflection Test methodology) prior to implantation or individual review of previous MR imaging of the clip/brain in that particular case, if available.
