Phase Contrast MR as Non-Invasive Tool in the Diagnosis of Benign Intracranial Hypertension.
Idiopathic intracranial hypertension (IIH) is characterized by an increased intracranial pressure in the absence of expansive lesions or cerebrospinal fluid (CSF) circulation obstructions. Its physiopathology is still not fully understood. The diagnosis is currently established on clinical grounds (Dandy criteria) along with an invasive measurement of CSF dynamic parameters through the infusion test. This study compares the invasive pressure measurements with the biomechanical CSF parameters derived from a phase-contrast MR protocol to evaluate the accuracy and reliability of the phase-contrast MR protocol.
