Abstract

MR spectroscopy in the myocardium is complicated, due to the presence of cardiac and respiratory motion, as well as the vicinity of the strong susceptibility boundaries to the lung and arteries. Therefore, excellent B0 shim quality is essential. Here we present an optimized B0 shimming approach by comparing projection based and image based B0 shim routines in combination with respiratory gating and ECG triggering at 3T.
