Usefulness of sagittal DWI sections for diagnosis of acute phase brain-stem infarctions: Report of two cases

Abstract

We report here two cases of acute brain-stem infarction diagnosed using axial images plus sagittal images of diffusion weighted magnetic resonance imaging (DWI). Routine DWIs for the diagnosis of acute cerebral infarctions are usually visualized as axial sections. Brain-stem infarctions are, however, sometimes difficult to display only on axial DWI sections, due to the size of the lesions and pathophysiological delay of signal changes. The usefulness of a combination of multiple DWI sections in the diagnosis of acute phase brain-stem infarctions is demonstrated.
