Non‐contrast estimate of blood–brain barrier permeability in humans using arterial spin labeling and magnetization transfer at 7 T

Blood–brain barrier (BBB) dysfunction is associated with a number of central nervous system diseases. This study demonstrates the application of a novel noninvasive technique to measure the BBB permeability in the human brain at 7 T. The technique exploits the fact that, when tissue macromolecules a...
