The current gold standard for imaging left ventricular function is electrocardiogram gated cine MRI with balanced steady-state of free precession imaging, which provides excellent myocardium-to-blood contrast. However, it yields non-diagnostic quality images in patients with arrhythmias because data acquisition is synchronized to cardiac rhythm and spread over multiple heart beats. We have developed an 8-fold accelerated non-gated cardiac cine sequence using k-t SPARSE-SENSE. We will evaluate this pulse sequence for assessment of cardiac function in the context of tachycardia, where high temporal resolution is critically important for diagnostic confidence.
