Coronal DW-EPI can more easily demarcate ischemia in the brainstem and/or cerebellum than axial scans when susceptibility artifacts are present as in this case wherein axial DW scan was read as equivocal while coronal DWI confirms the acute infarction. Coronal scans also demonstrate the site and direction of the pyramidal tract and its anatomical correlation with the lesions.
