Increased intracranial pulsations are seen in idiopathic normal pressure hydrocephalus.
We compared intracranial pulsations from continuous computerised intracranial pressure (ICP) monitoring and cine-MRI cerebrospinal fluid flow studies.
No correlation existed between intracranial pulsations measured with ICP monitoring and cine-MRI.
ICP pulsations can vary considerably over a period of hours which obscure snapshot MRI measurements.
