Imaging of the heart function in mice is challanging due to rapid cardiac and respiratory motion. Where initally cardiac imaging was introduced by syncronization of the data acquisition to the cardiac and respiratory phase, self-gating approaches have been intriduced providing excellent image quality without the hazzles of limited ECG quality and disturbances of the steady-state.
Recently sampling on radial trajectories with golden angle angular spacing has shown to provide self-gating as well as realtime imaging capabilities from the same continuously acquired data set. The presentation will summarize the principles of golden angle data acquisition and present examples for applying this technique to the assessment of cardiac function and perfusion in mice @11.7T.
