Figure 1

A. the Velocity selective pulse is made using a symmetric BIR4 for reduced eddy current sensitivity and bipolar gradients to prevent spatial signal modulation in static tissue. B. Coronary arterial blood (red) is saturated by VS labeling at mid-diastole with a velocity cutoff of 10 cm/s. Left: Gz "off" (T2 weighting only) Right: Gz "on" (T2 weighting + velocity selective saturation).
