Timing diagram for the 3D cine DENSE pulse sequence. Timing diagram for the 3D cine DENSE pulse sequence. Upon detection of an ECG trigger, a displacement-encoding module is played out. Phase cycling of the second radiofrequency pulse is used for artifact suppression. The displacement-encoding module is followed by successive multiphase applications of a readout module, which includes a displacement unencoding gradient. A stack-of-spirals k-space trajectory is used to achieve efficient data sampling. For mouse heart imaging at 7T, a relatively short spiral readout is used to reduce off-resonance-induced blurring.
