Spin-lattice relaxation rates ( R 1 ) and its associated dispersion over a range of magnetic field shifts (Δ B 0 ) provide useful quantitative tools to differentiate normal and abnormal tissues. We present preliminary imaging results for whole-body R 1 and R 1 dispersion maps of 0.11 T magnetic field shifts about 1.5 T at 37 o C for a healthy mouse using delta relaxation enhanced magnetic resonance (dreMR) imaging. The findings demonstrate unenhanced tissues exhibit little magnetic field dependence about 1.5 T.
