FIG 1. Coronal T1-weighted postcontrast image (TR/TE, 635/17) (A), axial DW image (TR/TE, 4300/122; b = 1000) (B), and axial GE CBV (C), CBF (D), MTT (E), and TTP (F) maps of the brain in a patient with an uncomplicated DVA (case 1). The postcontrast image demonstrates a DVA in the left frontal lobe. DW image demonstrates flow void in the central draining vein of the DVA, but no restriction of diffusion. Perfusion maps show increased signal intensity within the DVA and in the surrounding parenchyma on CBV, CBF, MTT, and TTP maps.
