We compared standard and RMT reconstructions for a prostate DWI exam on a prototype 0.55T for varying number of averages (1 to 40) to evaluate the image quality and overall loss. For standard reconstructions, regardless of number of averages, the Rician bias is present even at 40 averages for high-b value data, whereas 1 average on RMT is sufficient to produce diagnostic grade DWI at 0.55T.
