Sodium (23Na) MRI has the potential to provide insight to many diseases however 23Na MRI requires nonstandard hardware. This work compares two different designs of RF coil; a single channel pair of transmit-receive (Tx/Rx) loops and a 1Tx-6Rx flexible wraparound coil. Firstly, a 3D gradient-recalled-echo (GRE) sequence was optimised for each coil, then the signal-to-noise ratio (SNR) and field of view (FOV) was compared in both a phantom and in-vivo in a healthy control. SNR was 7±3 and 12±4 for the loops coil and the 6-channel coil respectively.
