GRE B0 inhomogeneities at different TEs. Short-axis images acquired with a GRE sequence at two different TEs (a) 2 ms and b) 10 ms). Both magnitude and phase images are shown. The arrows point at two local field distortions (RV apex of the heart and in the proximity of a pulmonary vessel) that generate signal loss in the surrounding region as TE becomes larger.
