Dynamic contrast-enhanced imaging (a, c) and ADC maps (b, d) in a 77-year-old woman with invasive breast cancer NOS diagnosed by biopsy to show the method used for placing ROIs to obtain the tumour-ADC, peritumoral maximum-ADC and the mean ADC of the contralateral breast parenchyma. Regarding the tumour-ADC, the slice with the largest tumour cross-section is selected and the largest oval or round ROI is placed inside the tumour (b) with reference to dynamic contrast-enhanced imaging (a). The mean value of the ROI (1047 × 10 mm /s) is recorded as the tumour-ADC. For the peritumoral maximum-ADC, three ROIs are placed where the ADC visually appears to be most increased on breast parenchymal tissue adjacent to the tumour contour on ADC maps (b): the three ROIs are 2054, 1892 and 1778 × 10 mm /s, respectively. The maximum value (2054 × 10 mm /s) is recorded as the peritumoral maximum-ADC. On 3 slices of ADC maps, a ROI as large as possible is subsequently placed on the contralateral normal breast parenchyma (mean ADC values = 1226, 1289 and 1481 × 10 mm /s, respectively) not to include abnormally enhanced breast parenchyma or fat intervening the breast tissue (d) with reference to dynamic contrast-enhanced images (c). The mean value of the three ROIs (1332 × 10 mm /s) is recorded as the mean ADC of the contralateral breast parenchyma
