This article reviews the pathophysiology and imaging appearances of cerebral edema or increased water content. CT is the initial screening examination for patients presenting with new-onset neurologic symptoms. We conclude that HACE is characterized on MRI by reversible white matter edema with a predilection for the splenium of the corpus callosum.
Blurring of the grey-white junction. Still both modeling results from pre-diagnosis and initial diagnosis head MRIs consistently indicate that the necrotic core increased the 95 metrics for electric field SAR and CD of the GTV. Cytotoxic cerebral edema where the blood-brain barrier remains intact.
However MRI studies investigating in which structure or tissue type a generalized brain edema is best detected are sparse.
