  • The remarkable success of magnetic resonance imaging of adult brain relates to the unusually large ratio of the longitudinal relaxation rates 1 / T1 of white and gray matter, ∼2:1 at physiological temperature and traditional imaging fields. Several investigators have conjectured that myelin is the source of the greater 1 / T1 of white matter without, however, suggesting details of the molecular mechanisms responsible. From measurements of the magnetic field dependence of 1 / T1 (NMRD profiles… CONTINUE READING
