B0 field variations in spine imaging due to respiration can also be a potential problem due to its close proximity to the lungs. The degree of B0 fluctuations during respiration has not been studied for spine imaging however. This study therefore focuses on the relative B0 fluctuations induced by susceptibility changes attributed to respiration in different parts of the spine. It is shown that B0 variations of up to ~23 Hz (C spine), ~47 Hz (T spine), and ~25 Hz (L spine) occur while breathing.
