Popis: We propose a new reliable transverse sinus stenosis (TSS) index based on magnetic resonance venography (MRV) for the diagnosis of idiopathic intracranial hypertension (IIH). Our quantitative semi-automatic measurement analysis based on segmentation and cross-sectional TS diameter from 48 IIH patients and controls matched for age and sex, had a good inter-observer agreement (κ=0.729) compared to a visual examination (κ=0.467). A cut-off point≥2 discriminate IIH patients from controls, with a sensitivity and specificity of 100%.
