Spinal cord MRI is notoriously challenging, in part due to the fact the spinal cord is near the lungs, causing magnetic field inhomogeneities that are changing throughout respiration. We propose a novel solution, called real-time z-shimming to address this problem. Real-time z-shimming involves compensating for magnetic field inhomogeneities that arise during image acquisition, by adapting the sequence in real-time. Our findings show that real-time z-shimming can recover signal loss, caused by respiration-induced magnetic field inhomogeneities, in the spinal cord region.
