Breast tumors: evaluation with P-31 MR spectroscopy. 1986

H Degani, and A Horowitz, and Y Itzchak

Differences in the energetics of breast carcinomas and benign breast tumors were monitored by recording their high-energy phosphate concentrations using phosphorus-31 magnetic resonance (MR) spectroscopy. Analysis of the P-31 spectra of biopsy samples from five benign breast tumors and nine breast carcinomas showed that the concentrations of nucleoside triphosphates and phosphomonoesters are consistently higher in the carcinomas than in the benign tumors by an average factor of about three. In addition, the chemical shift differences between the alpha-adenosine triphosphate (alpha-ATP) and beta-ATP signals and between the gamma-ATP and beta-ATP signals were larger by about 0.2 ppm in the carcinomas. These differences result from the lower fraction of magnesium-bound ATP found in the carcinomas under our experimental conditions and reflect a decrease of about two in the concentration of free magnesium ions in the carcinomas relative to that in the benign tumors. Despite the limited number of tumors studied, the results suggest that in vivo P-31 MR spectroscopy may become a reliable method for the diagnosis of breast tumors.
