Fig 1. Example of the measurement technique of relative ADC values.

Fig 1

The PHE ROI (solid line, right patient side) was transferred to a mirror region (left patient side) and then manually adjusted. Median absolute ADC values of the PHE (solid line), PDR (dotted line), and IPH (not shown) were each divided by median ADC values of the mirror region to calculate the corresponding relative ADC value.
