Figure 8From: Three-dimensional observation of Virchow–Robin spaces in the basal ganglia and white matter and their relevance to idiopathic normal pressure hydrocephalusVirchow–Robin spaces (VRS) in an 82-year-old patient with idiopathic normal pressure hydrocephalus (iNPH). In iNPH, constructive interference in the steady state images (a–c) showed few VRS in the white matter, in contrast to abundant VRS in the basal ganglia. A moderate degree of hyperintensities was noted in the periventricular and semioval center white matter. Corresponding images of fluid attenuated inversion recovery (FLAIR) are shown in d–f.
