Optimal b-values for maximisation of liver tumour ADC accuracy and contrast are calculated based on a statistical evaluation of ADC data from studies investigating diffusion weighted imaging of hepatic disease. It is shown that b-values of 0 and 900 s mm-2 should be used in a 1:3 ratio and evidence is given which supports these results.
