Idiopathic normal pressure hydrocephalus is of a great interest among neurologists and neurosurgeons for past decades. This neurodegenerative on its origin disease leads to severe disability in patients older 60 suffering from gait disturbance, cognitive impairment and urinary incontinence. Unique feature of this disorder is reversibility of symptoms after CSF shunting. Traditional diagnostic algorithms include invasive tests, such as spinal tap-test or external lumbar drain placement. Applying of these tests consist with complications, requires hospital stay and decrease patient’s compliance with treatment. Current literature contains increasing number of publications describing possibilities and advantages of non-invasive diagnosis of iNPH compared with standard algorithm. Thus, one of perspective diagnostic modalities is an assessment of routine brain MRI with complex analysis of specific features. We retrospectively reviewed MRI data of 117 patients that were surgically treated in our department from 2015 to 2023. Additionally, phone questioning performed to divide them in two categories: VP-shunt responders and non-responders. Complex analysis and comparison of MRI data performed reviling specific predictors of positive response to shunting
