Evidence is given that computed high b-value images based on ADC calculations present improved image quality over acquired images at the same high b-value. Two example cases are shown, the first demonstrating the improved SNR of computed over acquired b = 1400 s mm-2 images of iliac crest metastases and the second assessing the viability of extrapolating computed prostate images to b = 2000 s mm-2.
