AI Summary & Key Takeaways
AI InsightThe presence of lipid signals and absence of other signals suggest a diffuse metabolic defect in association with GnRHa treatment, possibly consistent with decrease in myoflaments, and increase in apopitosis and necrosis.

Abstract
MR spectroscopy uses the same hardware as magnetic resonance imaging but provides information at the biochemical level. It has been used to measure proton-containing compounds, such as amino acids, fatty acids, organic acids, sugars and other metabolic active compounds in tissue specimens. Before and after GnRH-a treatment we measured lipid, lactate, creatine and choline concentrations in two patients with uterine leiomyomas using single-voxel proton MR spectroscopy. Subcutaneous goserelin acetate injection was performed at least two times every 4 weeks before surgery. Spectroscopy was performed 3 weeks later last goserelin acetate injection. The MR spectroscopy results of leiomyomas before and after GnRH-a treatment were compared. Before GnRH-a treatment, spectral analysis of each patients showed only choline signals. After GnRH-a treatment, spectrum of both patients showed lipid peaks but the other signals were not observed. The presence of lipid signals and absence of other signals suggest a diffuse metabolic defect in association with GnRHa treatment, possibly consistent with decrease in myoflaments, and increase in apopitosis and necrosis.
