SENC Short-axis images for cardiac phases during early systole at location corresponding to the left ventricular basal section and at two different flip angles using: (a) Every Heart-Beat, and (b) Every Other Heart-Beat. For each image, the acquisition time, measured directly after the R-wave, appears above its column, and the used flip angle appears to the left of its row. The imaging parameters are 20 cardiac phases with temporal resolution of 20 ms. For the every heartbeat, 16 spiral was acquired with spiral window of 8 ms. For the every-other heartbeart, 8 spiral was acquired with spiral window of 16 ms.
