      Cardiac magnetic resonance imaging (MRI) serves as a clinical gold-standard non-invasive imaging technique for the assessment of global and regional cardiac function. Conventional cardiac MRI is limited by the long acquisition time, the need for ECG gating and/or long breathhold, and insufficient spatiotemporal resolution.

Conventional metal artifact reduction sequences (MARS) with high bandwidth allow a moderate reduction of metal artifacts (c). Advanced MARS techniques further reduce in-plane (view angle tilting; VAT; d) and through-plane (SEMAC; e) metal artifacts.
