The method for quantitative water content mapping
of a human brain at high magnetic field was proposed. We demonstrated that B1-
is proportional to B1+ in a uniform area even on a nonuniform image
measured at 4.7T. B1-s of the reference phantom and a human brain
can be compared by measurable B1+s in uniform areas and water
content of human brain can be computed from that comparison. Our method was
validated in the experiments of the mixture phantom of H2O and D2O. Quantitative
water content maps of human brains were obtained by our method.
