In vivo 13C nuclear magnetic resonance spectroscopy using a solenoid transmit/receiver coil.

Topical nuclear magnetic resonance spectroscopy (NMR) using a solenoid transmit/receiver coil has been used to monitor the kinetics of intragastric utilization of [1-13C] glucose in mice in vivo. Using a double-tuned solenoid coil, signal to noise response was excellent and the natural abundance in vivo 13C spectra obtained with acquisition times of 10-15 minutes compares more than favourably with comparable studies using surface or saddle coils. This study clearly shows the potential of solenoid coils to monitor the kinetics of 13C-labelled metabolites in vivo.
