  1. Table 1 summarizes the sequence parameters for the balanced TFE sequence and for the PC MR sequence. The former was used for LV-imaging and positioning of the PC MR, and the latter for flow measurements in the CS. Varying parameters are given as the average of the values used for the different scans, and marked with *.
