SNR improvement of a 13 C-cryo-coil in comparison with room-temperature coils

Introduction MRS studies typically require a high signal-to-noise ratio (SNR), especially for C-spectroscopy where the low natural abundance of C (1.1%) is a problem. Since the SNR depends on the third power of the Larmor frequency, the relative small frequency of C increases this limitation for C in comparison with HMRS. There are methods to enhance the… (More)
