Intracranial Pressure Dynamics and Cerebral Vasomotor Reactivity in Coronavirus Disease 2019 Patient With Acute Encephalitis.

Unlabelled: We describe the intracranial pressure dynamics and cerebral vasomotor reactivity in a coronavirus disease 2019 patient with acute encephalitis treated with cerebrospinal fluid drainage and therapeutic plasma exchange.

Data Sources: Coronavirus disease ICU, Uppsala University Hospital, Sweden.

Study Selection: Case report.

Visual rating versus volumetry of regional brain atrophy and longitudinal changes over a 5-year period in an elderly population.

Introduction: The purpose of our study was to compare visual rating and volumetry of brain atrophy in an elderly population over a 5-year period and compare findings with cognitive test results.

Materials And Methods: Two hundred and one subjects were examined with magnetic resonance imaging (MRI) of the brain. Visual rating and volumetry were performed in all subjects at ages 75 and 80.

Visual Assessment of Brain Perfusion MRI Scans in Dementia: A Pilot Study.

Purpose: Functional imaging is becoming increasingly important for the detection of neurodegenerative disorders. Perfusion MRI with arterial spin labeling (ASL) has been reported to provide promising diagnostic possibilities but is not yet widely used in routine clinical work. The aim of this study was to compare, in a clinical setting, the visual assessment of subtracted ASL CBF maps with and without additional smoothing, to FDG-PET data.
