Coronal T2 (A) and axial T1 FLAIR (B), T2 (C), and SWI (D) MR images of a 6-day-old boy. Coronal T2 (A) and axial T1 FLAIR (B), T2 (C), and SWI (D) MR images of a 6-day-old boy. Global severity score = 3 (first quartile) (E). There is diffuse bilateral WM signal abnormality of cerebral edema without infarction (3 points) (A and B). The DMVs are prominent bilaterally, seen on T2 (C) and SWI (D) (ovals). No WM lesions are visible. R indicates right; L, left. K.L. Benninger et al.
