![Schematic flow of image preprocessing steps (details are in Appendix E3 [supplement]). Raw k-space data from one diffusion-weighted (DW) scan is reconstructed to produce three types of images: guidance (low b-value DW image reconstructed with all available averages), noisy (high b-value DW image reconstructed using two averages), and reference (high b-value DW image, reconstructed using 16 averages).](https://www.ncbi.nlm.nih.gov/core/lw/2.0/html/tileshop_pmc/tileshop_pmc_inline.html?title=Click%20on%20image%20to%20zoom&p=PMC3&id=8082338_ryai.2020200007.fig1.jpg)
