Ultra-high field (UHF) 7T MRI provides high spatial resolution with significantly better signal-to-noise ratio compared to 3T and C-spine imaging at 7T is being pursued at a few research sites across the globe. MRI of the C-spine at 7T is challenging due to multiple factors. Recently, an algorithm ‘Uniform Combined Reconstruction’ (UNICORN) was used to correct receive-coil intensity inhomogeneity and improve the uniformity and overall image quality of 7T knee MRI. In this work, we present preliminary results from the application of UNICORN to C-spine imaging and demonstrate the utility of UNICORN in improving uniformity of C-spine MRI at 7T.
