A poor tumor response to CRT, with an Ohboshi and Shimosato classification of I. The analyses were performed using a proprietary software program (PRIDE software, Philips Healthcare, Eindhoven, The Netherlands). Pre-CRT (a–c), Gd-enhanced T ₁ WI (a), K ^trans⁡ map (b), v _e map (c), Post-CRT (d–f), Gd-enhanced T ₁ WI (d), K ^trans⁡ map (e), v _e map (f). The tumor ROIs are delineated in red (a, d). The pre-CRT K ^trans⁡ was 0.13 and K ^trans⁡ decreased after CRT with an average of 0.10. v _e decrease from 0.28 to 0.23.
