Figure 5

Impact of different noise levels on T1 maps from gel phantoms. Left panel: When all data are taken into account, there is severe background noise from the air surrounding the phantoms. Middle panel: Setting a low noise level discards virtually all of the background noise from air and only leaves noise close to the phantom borders caused by susceptibility artifacts of the phantoms. Right panel: Setting a higher noise level also removes the noise (i.e. blackens affected pixels) from susceptibility artifacts.
