Abstract

In ^31^P‐ {^1^H} MR experiments of humans in a 1.5‐T whole‐body system, signal intensity enhancements of ^1^P 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 ^1^H and ^1^P spins. © 1990 Academic Press, Inc.
