Abstract

We report the performance of a cryogenic RF receive-only coil for 13C imaging of small animals. It is experimentally demonstrated 2-fold SNR improvement in comparison to a room temperature coil in immediate vicinity of the sample. The self-developed cryostat employed for coil cooling shows thermal stability within 5 h of use for 6 L of LN2 , which can be extended up to 12 h if more LN is added. The Q88K /Q290K ratio of
the unloaded coil is 550/285
