“…MRI‐guided catheterization procedures use foot‐pedals to leave interventionist hands available for device manipulation, which mimics traditional x‐ray catheterization suites. Other auxiliary equipment including computer mice, keyboards, and tablets have been explored for interactive imaging, 83 as well as gesture‐based scan control 84 . Furthermore, augmented reality and virtual reality equipment 85 may be attractive for interactive visualization of real‐time imaging in the future.…”

Real‐time magnetic resonance imaging (RT‐MRI) allows for imaging dynamic processes as they occur, without relying on any repetition or synchronization. This is made possible by modern MRI technology such as fast‐switching gradients and parallel imaging. It is compatible with many (but not all) MRI sequences, including spoiled gradient echo, balanced steady‐state free precession, and single‐shot rapid acquisition with relaxation enhancement. RT‐MRI has earned an important role in both diagnostic imaging and image guidance of invasive procedures. Its unique diagnostic value is prominent in areas of the body that undergo substantial and often irregular motion, such as the heart, gastrointestinal system, upper airway vocal tract, and joints. Its value in interventional procedure guidance is prominent for procedures that require multiple forms of soft‐tissue contrast, as well as flow information. In this review, we discuss the history of RT‐MRI, fundamental tradeoffs, enabling technology, established applications, and current trends. Level of Evidence 5 Technical Efficacy Stage 1
