The adiabatic version of refocused insensitive nuclei enhanced by polarization transfer (BINEPT) and pulse acquire (PA) 31P Magnetic Resonance Spectroscopy (MRS) are compared in MCF-7 and MDA-MB-231 breast cancer xenografts at 9.4 Tesla. After in vivo MRS measurements, the tumors were extracted and high-resolution (HR) 31P MRS was performed. Our data suggest that BINEPT can be advantageous for studying the individual compounds in phospholipid metabolism in both the choline and ethanolamine cycle, in translational research in breast cancer and other cancers in vivo at high magnetic field strength.
