WebThe aim of this study was to investigate the usefulness of high-b-value computed DWI (c-DWI) in comparison to standard DWI in patients with acute brainstem infarction. Materials and methods: 56 patients with acute brainstem infarction were retrospectively analysed by two readers. DWI was obtained with the b-values 0, 500 and 1000 s/mm² on ... WebDiffusion-weighted imaging (DWI) DWI 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.
