With DWI scans, ischaemia can be visualised within minutes of it occurring (Figure 5). This is because DWI has a high sensitivity for water diffusion, thereby detecting the physiological changes that happen immediately after a stroke.

WebA typical DWI sequence for routine brain MRI protocols includes a b factor of 1000 s/mm 2 (ideal between 700 and 1300 s/mm 2 ). At high b values, the signal intensity will be reduced. A b value of zero means application of the normal single-shot EPI sequence without diffusion weighting. WebBrainstem syndromes are most commonly due to occlusion of the posterior circulation or mass effect from intrinsic space-occupying lesions. These syndromes can have subtle imaging findings that may be missed by a radiologist unfamiliar with the anatomy or typical manifesting features.
