Figure 1

Field distortion for the first pass of Gd-DTPA in the heart for one of the patients. From left to right we have the first pass of contrast agents in the right ventricle, the left ventricle and during recirculation. During the first pass in the LV, all patients showed an increase of B0 in the posterior and anterior myocardial segments (brighter regions) and a decreasing of B0 in the septal and lateral segments (darker regions). The in plane component of B0 is shown.
