Microemulsions have recently been proposed as the signal-bearing solution for use in a magnetic resonance imaging phantom. We have attempted to characterize the hydrogen nuclear spin system of paramagnetically doped water, n-decane, bis(2-ethylhexyl_ sulfosuccinate (AOT) reverse micelle solutions. Overall spin-lattice and spin-spin relaxation times, T1 and T2, respectively, are presented for volume fractions in the range 0.50 < φ < 0.75 at temperatures between 0 and 40°C. Measurement of the room temperature spin-lattice relaxation times for the individual water and decane components of the reverse micelle are also presented.
