Fast-SENC imaging has been proposed as a technique that can image regional function of the heart in a single heart beat. In this study, the feasibility to use fast-SENC imaging at 3T has been demonstrated. A fast-SENC imaging sequence with interleaved spiral acquisitions has been implemented on a 3T system to measure the regional function of the heart. The images were acquired both in normal subjects, and post-infarction patients with identified dysfunctional region compared with delayed enhancement imaging. Fast-SENC shows its potential to dynamically detect the onset of ischemia during dobutamine stress test, or image the patients with cardiac arrhythmia.
