They investigated prostate lesion segmentation accuracy by training a segmentation network using acquired DWI (aDWI) or computed DWI (cDWI) at different b values.
The results showed, best segmentation accuracy with a network trained and tested with high b values (b1500), robustness against different b values during training, and a general finding that lesion segmentation networks are less sensitive to different measured b values, than to computed higher b values.
