Even though an established imaging method, small animal cardiac MRI is a time-consuming technique. Where self-gating techniques enabled wider-spread applications, acquisition times in the minute range for a single slice still limit its application for physiological stress or first-pass perfusion imaging. We translated the tiny golden angle sparse sense approach to small animal application. The technique was tested in ten animals and the resulting functional parameters compared with the self-gating approach. Further, initial application for pharmacological stress imaging was tested in three animals.
