Brain aging is a complex process that affects everything from the subcellular to the organ
level, begins early in life, and accelerates with age. Morphologically, brain aging is primarily …

With an ever-growing aging population, the prevalence of normal pressure hydrocephalus
(NPH) is increasing. Clinical symptoms of NPH include cognitive impairment, gait …

Background and purpose Assessment of ventricular enlargement is subjective and based on
the radiologist's experience. Linear indices, such as the Evans Index (EI), have been …

The diagnosis and management of idiopathic normal-pressure hydrocephalus (iNPH), a
disorder of gait impairment, incontinence, and dementia that affects elderly patients …

Although the diagnosis of dementia still is primarily based on clinical criteria, neuroimaging
is playing an increasingly important role. This is in large part due to advances in techniques …

Purpose To assess the diagnostic performance of the callosal angle (CA) and Evans index
(EI) measures and to determine their role versus automated volumetric methods in clinical …

BACKGROUND AND PURPOSE: Despite the remarkable progress of 3D graphics
technology, the Evans index has been the most popular index for ventricular enlargement …

Objective: The intracranial pressure (ICP) and CSF outflow resistance (Rout) are essential to
describe the dynamics of the CSF system. Rout affects ICP, pulse amplitudes, CSF …

Background and purpose Evans index is an estimate of ventricular size used in the
diagnosis of idiopathic normal‐pressure hydrocephalus (iNPH). Values> 0.3 are considered …

Ventricle sizes are important for the early diagnosis of hydrocephalus or for follow-up after
ventriculostomy. Diameters of ventricles may change, especially in childhood. This study …
