Virchow-Robin Spaces
Virchow-Robin spaces (VRS) are perivascular, fluid-filled canals that surround perforating arteries and veins in the parenchyma of the brain. VRS are extremely small and can usually only be seen on MR images when dilated. While many normal brains will show a few dilated VRS, an increase in dilated VRS has been shown to correlate with the incidence of several neurodegenerative diseases, making the spaces a popular topic of research.

Famous quotes containing the word spaces:
“Though there were numerous vessels at this great distance in the horizon on every side, yet the vast spaces between them, like the spaces between the stars,—far as they were distant from us, so were they from one another,—nay, some were twice as far from each other as from us,—impressed us with a sense of the immensity of the ocean, the “unfruitful ocean,” as it has been called, and we could see what proportion man and his works bear to the globe.”
—Henry David Thoreau (1817–1862)
