NEMA Publishes MS 1-2008 Determination of Signal-to-Noise Ratio (SNR) in Diagnostic Magnetic Resonance Imaging
Press release date: May 13, 2008
MS 1 is part of a series of test standards developed by the medical diagnostic imaging industry for the measurement of performance parameters governing image quality of magnetic resonance imaging (MRI) systems. First developed in 1988 to define a standard procedure for measuring a useful index of image quality performance for MRIs, MS 1 describes four methods to measure image SNR. It is intended for use by MRI manufacturers, manufacturers of accessory equipment (including radiofrequency coils), and by MRI end-users.
MRI standards pertaining to SNR and uniformity measurements have been restructured to consider the coil geometry. In addition, new measurement methods have been added to this standard. The parameters serve as a guide to those factors that can influence the measurement. These standards also serve as reference procedures for acceptance testing and periodic quality assurance.
