Abstract:
We developed a new transvaginal coil tuned for phosphorous-31 and measured its magnetic resonance spectroscopy ((31)P MRS) of uterine cervical cancer. In a 50-year-old woman with uterine cervical cancer (International Federation of Gynecology and Obstetrics [FIGO] stage IIIb), (31)P MRS with the new coil clearly differentiated the low intensity of phosphocreatinine (PCr) and high intensity of phosphomonoester (PME) in tumor from those in muscle. Results suggests that this method will be useful for assessing uterine cervical cancer.

While fluorine-19 and phosphorous-31 have high natural abundances (100%) and positive gyromagnetic ratios, nitrogen-15 has a low natural abundance and a negative gyromagnetic ratio. However, nitrogen-15 is still preferred over nitrogen-14 (which has a high...
