✦ Synopsis

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 paramagnetieally doped water, n-decane, bis(2-ethylhexyl) sulfosuccinate (AOT) reverse micelle solutions. Overall spin-lattice and spin-spin relaxation times, TI and /'2, respectively, are presented for volume fractions in the range 0.50 < ~b < 0.75 at temperatures between 0 and 40 °C. Measurements of the room temperature spin-lattice relaxation times for the individual water and decane components of the reverse micelle are also presented.
