Abstract
A method of measuring the concentration of a magnetic material in an object using magnetic resonance imaging comprising administering magnetic material to the object; obtaining a set of T-weighted and T-weighted images of the object in order to determine a background magnetic resonance imaging signal intensity and measurements of the background nuclear magnetic relaxation times (T, T) of the object without magnetic material; and obtaining a set of T-weighted and T-weighted magnetic resonance images of the object with magnetic materials added; measuring effect of magnetic material on the relaxation times; and converting the T-weighted and T-weighted images into a set of contrast images which are subtracted from each other to yield a contrast difference image proportional to the concentration of the magnetic material.
