In Vivo Phosphorus MR Spectroscopy Demonstrates the Heterogeneous Composition of Sarcomas

Fernando Arias-Mendoza¹, Truman R. Brown¹

Proper spectral and spatial analysis of 3D localized ³¹P MRS acquired from the tumor masses of 20 sarcoma patients was performed. The analysis helped stand out the diverse metabolic characteristics of the sarcoma masses due to their heterogeneity improving their correlation with malignant behavior and thus outcome to treatment and survival.
