Medical Diagnostic Standard Tests Safety of MRI Systems

ROSSLYN, Va.—Today, the National Electrical Manufacturers Association (NEMA) published NEMA MS 8-2016 Characterization of the Specific Absorption Rate (SAR) for Magnetic Resonance Imaging Systems.

"MS 8 was substantially revised to consider the implications of higher field systems, larger bore sizes, and new sensor technologies," said Michael Steckner, senior manager, MR Research at Toshiba, and MITA MR technical committee chair.

MS 8 is one of a series of test standards developed by the medical diagnostic industry that measures performance parameters related to the safety of magnetic resonance imaging systems. These test standards are intended for the use of equipment manufacturers, prospective purchasers, and users alike. MS 8 describes calorimetric and pulse energy methods of whole-body SAR measurements, and specifies tests for volume radio frequency transmit coils that produce relatively homogeneous radio frequency fields.  

NEMA MS 8-2016 is available in hard copy for $87 and as an electronic download at no cost on the NEMA website.


The National Electrical Manufacturers Association (NEMA) represents nearly 325 electrical equipment and medical imaging manufacturers that make safe, reliable, and efficient products and systems. Our combined industries account for 370,000 American jobs in more than 6,100 facilities covering every state. These industries produce $124 billion in shipments and $42 billion in exports of electrical equipment and medical imaging technologies per year.
