MRI detects a contralateral white matter lesion at late, but not early, time points. Panels include post-contrast T1-weighted image, MTR map, and ADC map (from left to right) of a representative mouse at week one (top row) and week 12 (bottom row) post-irradiation (PIR). Notice the signal enhancement on the right hemisphere at 12 weeks versus one week PIR on all but post-contrast T1.
