MR Image Quality with the Defibrillator Turned On and Off. bSSFP images were obtained when defibrillator was switched off (a) and switched on (b). Note the reduction in image quality (due to increased noise level) when the defibrillator was switched on (b) compared with when it was switched off (a). The images were used to calculate SNR as previously described [11]. There was an approximate 10% reduction in SNR when the defibrillator was switched on. Bottom: image artifact caused by defibrillator pads (d, arrow) compared with the same image without the pads (c)
