Answer

A baseline brainstem diffusion-weighted imaging (DWI) lesion score can be used as an independent predictor for clinical outcome in patients with basilar artery thrombosis. [12]

The total number of brainstem arterial territories with abnormal DWI defines the brainstem DWI lesion score, which ranges between 0 and 22. A score of 0 indicates absence of visible posterior circulation ischemia; a score of 22 indicates DWI restriction in the entire brainstem. [12]
