Figure 4

Full field of view rest scans in 4 patients with no myocardial infarction. In the first two patients, the low flip angle SSFP PD frames contain banding artifacts on top of the myocardial region of interest (yellow arrows in images a, d and g), while the high flip angle SSFP perfusion frames (c, f and i) and the FLASH PD frames (b, e and h) do not. These ghosting artifacts repeat themselves 3 times, which is consistent with the parallel imaging acceleration factor of 3 used for these acquisitions. In the fourth patient, none of the images contain banding artifacts on top of the LV region of interest (j, k and l).
