Signal of diffusion-weighted imaging (DWI) with increasing b-values from b = 0 s/mm² to b = 1000 s/mm² (a) and signal of DW-DESS-Cones with increasing diffusion gradient amplitudes from 5 mT/m to 78 mT/m (b) for a range apparent diffusion coefficients (ADCs). Representative phantom images from DWI b = 600 s/mm², b = 1000 s/mm² and DW-DESS-Cones 47 mT/m, 68 mT/m. Signal decay with the two methods is highly correlated between DWI b = 0 s/mm² and b = 1000 s/mm² and DW-DESS-Cones diffusion gradient amplitudes 16 mT/m and 68 mT/m. Based on these experiments a b-value equivalent breast (b_eqbr) is defined (Table 1) to indicate expected level of diffusion-weighting for DW-DESS-Cones in this work
