Predictive value of diffusion for
relapse ?
•
52 patients
•
Correlation of ADC with relapse site
•
32 patients exhibited ADC
hypointensity outside of CE or
resection cavity.
•
Study of overlap of ADC hypointensity
with CE at recurrence and correlation
with RT dose.
•
ADC abnormality=regions of DWI
hyperintensity corresponding to an
area of ADC hypointensity
•
84% relapse central, 13% marginal.
