This review of methods of measuring spin-lattice T relaxation times 1 comprises 283 references, including 90 references on magnetic resonance imaging. Annotations give brief descriptions of each reference. References are organized by major categories, with cross-references to other topics. Major cat
The 29Si spin-lattice relaxation times, &(%), of the various silicate anions present in high-purity alkaline silicate solutions are reported. Regular silicate cages display the longest T,(29Si) values and, in the case of the cubic octamenc cage, an unexpectedly large nuclear Overhauser enhancement,
## Abstract __T__~1~ and __T__~2~ can be rapidly determined with a combination of multiangle spoiled gradient recalled echo (SPGR) and steadyβstate free precession (SSFP) imaging. Previously, we demonstrated a simple method for determining the set of SPGR and SSFP angles that provided greater __T__
