Abstract
In 31P-(1H) MR experiments of humans in a 1.5-T whole-body system, signal intensity enhancements of 31P 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 31P spins.
摘要
在1.5-T全身系统中对人体进行的31P-(1H)磁共振实验中，在质子频率照射下，观察到31P共振信号强度增强，其中小腿肌肉磷酸肌酸的增强幅度高达68±4%。这一观察结果被解释为由于1H和31P自旋之间的偶极耦合而产生的核奥弗豪泽效应。
