Diffusion restriction is the morphologic hallmark of acute ischemic infarcts and excitotoxic brain injury in various cerebral pathologies. visible as hyperintensity on DWI hypointensity ADC maps. Due to vicinity multiple anatomic structures stem hippocampus, very small lesions with diffusion may result severe clinical symptomatology, but these easily go undetected standard due insufficient spatial resolution, T2* blurring, image artifacts caused by susceptibility-related distortions. Diffusion-weighted zonal oblique multislice-EPI reduced FOV acquisition permits a considerable increase resolution enhances visualization pathologic hippocampus. Improved performance depiction different hippocampus using this sequence compared selected cases presented.
