Quality metrics of the non-diffusion images. (a) The regions of interest (ROIs) for measuring signal-to-noise ratio (SNR) and ghost-to-signal ratio (GSR) are outlined in orange and blue, respectively. Phase-encoding (PE) and readout (RO) directions are marked. (b) The minimum, median, and maximum values of five SNR measures for each scan. (c) The minimum, median, and maximum values of six GSR measures for each scan.
