Abstract: A method of analyzing a blood-brain barrier of a subject is disclosed. A detectable dose of an MRI contrast agent is administered to the subject, and a plurality of magnetic resonance images of the subject's brain are acquired over a predetermined time-period. Two or more of the magnetic resonance images are compared thereamongst so as to determine variations in concentration of the contrast agent in the brain, and blood-brain barrier function is assessed based on the variations.
