WebDWI is an MRI technique that is extremely sensitive for the detection of cytotoxic edema. It is highly specific and sensitive (> 95% for both) for the detection of acute ischemic infarcts and can differentiate acute from chronic infarctions. It has high signal-to-noise ratio and excellent interrater reliability. WebDWI was performed in the transverse plane using a spin-echo, echo-planar imaging sequence with the following parameters: TR/TE/inversion time, 12000/100/2200; diffusion gradient encoding in 3 orthogonal directions; b = 1000 s/mm 2; FOV, 220 mm; matrix size, 128 × 128 pixels; section thickness, 5 mm; section gap, 1 mm; and number of signals …
