Multi-channel acceleration of hyperpolarised 13C MRI is hindered by a lack of prior coil sensitivity profile knowledge. Here we harness a 13C tuned flexible multi-channel array to provide subject specific coil sensitivity measurements from 23Na and subsequent SENSE reconstruction of under-sampled hyperpolarised imaging data.
