INTRODUCTION:
Normal-pressure hydrocephalus is considered treatable form of dementia primarily affecting elderly, characterized by a classic triad of symptoms: gait impairment, cognitive decline, and urinary incontinence.
iNPH rad scale using T2 axial and coronal MRI imaging was used to assess the morphological pattern of patient with normal pressure hydrocephalus, serving as a diagnostic screening tool for discriminating normal pressure hydrocephalus patients for other diseases with overlapping symptoms as Alzheimer disease and vascular dementias, where iNPH score more than 8 is highly specific for normal pressure hydrocephalus diagnosis.
3D-CISS is a gradient-echo imaging technique with high CSF-to-aqueduct contrast. It provides anatomical information about morphology relationships of aqueduct before shunt surgery. It can be used to discriminate in determination of stroke volume across the aqueduct highlight patients whom would benefit from the shunt surgery.
The definitive treatment for iNPH is shunt surgery, thus its crucial to choose shunt candidates adequately.

AIM:
The aim of the work was to evaluate patients with clinically suspected normal pressure hydrocephalus.
