An example of apparent diffusion coefficient (ADC) measurements. A Axial T2-weighted image of a right frontal glioblastoma. B–D ADC maps showing the ROIs used to determine ADCmin (three different visually lowest ADC regions, red), ADCmean (largest tumor cross-section measurement, green), and ADCnawm (normal-appearing white matter in contralateral centrum semiovale, yellow)
