Figure 3

Left: Cylindrical phantom with susceptibilities similar to the ones obtained in the myocardium and left ventricle during the first pass, assuming 1% (5 mmol/L) of Gd-DTPA concentration in the LV. The angle shown is between B0 and the orientation of the long axis of the cylinder. When the cylinder lay across B0 (90 deg), corresponding to 'horizontal heart' morphology, phase distortions of around 60 Hz were measured in the subendocardial regions of the phantom. Right: numerical simulations of B0-field distortion based on the setup of the left. Similar phase distortions were obtained. The plane component of B0 is shown.
