Fig. 5From: The effect of high-permittivity pads on specific absorption rate in radiofrequency-shimmed dual-transmit cardiovascular magnetic resonance at 3TPlots of the over- or underestimation of SAR when using high permittivity pads. Blue refers to overestimation, i.e. the actual SAR is less than that calculated by the CMR system. Quadrature mode is indicated with the plus sign (+) and the RF-shim setting that maximizes B 1 + homogeneity is indicated by the circle (o)Back to article page
