Actual SAR values measured by calorimetry varied for a factor of 2.3 among three different scanners (two 1.5T and one 3T) even at identical console SAR settings. Console B1+RMS values also deviate for a factor of 1.2 between the two 1.5T. Image quality assessment performed by three radiologists suggested that the image quality change due to the console SAR setting was not critical at a 1.5-T scanner, but was so at a 3-T scanner. Therefore attention should be paid to the variation of the actual SAR even if the console SAR is at a condition specified for an implantable medical device.
