Example rest scan in a patient with no myocardial infarction. FLASH (a) and low flip angle SSFP (d) PD frames and their corresponding quantitative MBF maps (b and e respectively) and regional perfusion signal intensity curves from six sectors of the LV (c and f), as well as some representative frames from the high flip angle perfusion series (g). The low flip angle SSFP PD image (d) shows banding artifacts on top of the myocardium (yellow arrows), which lead to overcorrection of the SCIC, causing artefactual lower perfusion values in the inferior and inferolateral walls (e). This affects both the MBF maps and in the regional time intensity curves (f). The FLASH PD frames (a) are unaffected by banding artifacts, which leads to an improved SCIC, a more homogeneous MBF map (b) and better agreement between the regional time intensity curves (c).
