DWI (SS-SE-EPI-with fat suppression)DWI were acquired in a transverse plane, using three b values: low (0–50 s/mm2), intermediate (500 s/mm2) and high b value (1000 s/mm2).

ADC mapADC maps were calculated by the MR system via linear regression analysis of the natural log of signal intensity using all three b values
