Fig. 1From: Breath-hold imaging of the coronary arteries using Quiescent-Interval Slice-Selective (QISS) magnetic resonance angiography: pilot study at 1.5 Tesla and 3 TeslaPulse sequence diagrams for radial QISS (a) and 2D T2-prepared bSSFP (b). QISS (flow dependent) applies a slice-selective FOCI pulse for inversion of in-plane spins, followed by a quiescent interval (QI) to allow for replenishment of in-plane arterial spins. With T2-prepared bSSFP (flow independent), a spatially non-selective T2 preparation is appliedBack to article page
