| Popis: | In 31P- {1H} MR experiments of humans in a 1.5-T whole-body system, signal intensity enhancements of 1P resonances of up to 68 ± 4% (for phosphocreatine of the calf muscle) have been observed upon irradiation at proton frequency. This observation is explained as a nuclear Overhauser effect due to the dipolar coupling between 1H and 1P spins. © 1990 Academic Press, Inc. |
