Abstract

There is a clinical need for high-spatial-resolution, electrocardiography (ECG)-gated, respiratory-navigated contrast-enhanced (CE) thoracic MR angiography (MRA; hereafter, NAV CE MRA) robust to physiologic motion artifacts. Compared with first-pass gated techniques, ECG-triggered NAV MRA more effectively suppresses motion and exhibits greater acquisition efficiency and/or artifact mitigation than…
