(A) Representative patient images for classification of NEL type based on pre-CCRT T2 FLAIR images. Edema-dominant type NEL (left) and tumor-dominant type NEL (right). (B) Representative patient images for CE evolution pattern based on pre-CCRT (left) and post-CCRT (right) contrast-enhanced T1-weighted MRI. a) new non-measurable CE after GTR (pattern 1); b) stable or responding residual CE after STR (pattern 2); c) new measurable CE after GTR (pattern 3); and d) enlarging residual CE after STR (pattern 4). NEL = non-enhancing lesion; CE = contrast enhancing lesion; CCRT = concurrent chemoradiotherapy; GTR = gross total resection; STR = subtotal resection
