Computed diffusion weighted imaging (cDWI) is proposed
as a new technique that produces any b-value images from
acquired DWI (aDWI) with at least two different
b-values. Recently, high-resolution DWI of the prostate
had potential for improving the sensitivity to small or
sparse prostatic cancer (PCa). Thus, our aim was to
determine the influence of voxel size to cDWI with high
b value, and directly compare image quality and
capability for PCa detection with aDWI with high b-value
as obtained conventional and reduced voxel sizes at 3T
MR system.
