Dementia imaging: Normal pressure hydrocephalus (NPH) and other reasons for wide ventricles in the elderly.
Ventriculomegaly in older adults is assessed with emphasis on normal-pressure hydrocephalus and its imaging mimics.
Already have an account?
Description
Normal ageing, ventricular measurements, and mechanisms that produce wide ventricles are reviewed, including obstructive and arrested hydrocephalus. MRI protocol, Evans index, features of normal-pressure hydrocephalus, and a structured method for distinguishing NPH from other causes provide the diagnostic focus.
Learning Objectives
- Measure and describe ventriculomegaly using appropriate indices and imaging features.
- Differentiate normal ageing, obstructive or arrested hydrocephalus, and normal-pressure hydrocephalus.
- Apply an MRI protocol and structured evaluation to suspected normal-pressure hydrocephalus.
