•
ADC abnormalities overlap with the eventual recurrence in 88 % of cases
and the proportion of overlap is 60 %
•
The ADC hypointensity itself volumetrically is much smaller than the
recurrence volume
•
Patients with a region of diffusion restriction exhibited a significantly
reduced median progression free survival of 3.2 versus 8.0 months
Predictive value of diffusion for
relapse ?
