Respiratory motion induced B0 field fluctuations, constitute a challenge for B0 sensitive CMR like spectroscopy. Accommodating CMRS in a single breath-hold is elusive if not prohibitive. Motion corrected approaches under free breathing were demonstrated to substantially improve CMRS. Yet, B0 field fluctuations over the respiratory cycle may compromise spectral resolution and data integrity. A compensation strategy like dynamically updated first order shims synchronized with the respiratory motion, offers the potential to enhance spectral quality and permits scan time shortening. This work details respiratory motion induced B0 fluctuations in the interventricular septum and examines the capability of linear shimming for compensation of myocardial B0 fluctuations.
