Synopsis
In this study, the performance of Beat Sensor Cardiac (BSC) triggering was qualitatively and quantitatively compared with electrocardiogram (ECG) triggering. MR images typically acquired in a comprehensive exam including localizer, morphology, cine, 2D flow, parametric mapping and late gadolinium enhancement (LGE) were acquired using both BSC and ECG triggering in volunteers and patients. The overall image quality for BSC was equivalent to ECG. Quantitative measurements of function, flow, and parametric maps in healthy volunteers showed no significant differences except for peak aortic velocity.
