Fig. 2From: The role of perfusion and diffusion MRI in the assessment of patients affected by probable idiopathic normal pressure hydrocephalus. A cohort-prospective preliminary studyPeriventricular white matter perfusion changes in positive patients (PP). On the vertical axis relative perfusion values are reported [mean rCBF Periventricular/mean rCBF Occipital]. Rectangles represent data inter-quartile range (IQR) and straight lines represent standard deviation (SD). Data are represented for baseline evaluation, after test evaluation and post-surgery assessment. Asterisk indicates when the variation was statistically significantBack to article page
