Technical - Emerging CMR Methods - Motion Correction & Rapid Imaging-Real-Time CMR

Video Transcription

Video Summary

Jennifer Sleeden explains real-time cardiovascular MRI (CMR), which reduces motion artifacts and scan times, especially in children. She describes advances such as non-Cartesian trajectories, compressive sensing, and machine learning reconstructions. In studies of congenital heart disease, machine learning produced high-quality ventricular and flow images much faster than compressive sensing, enabling free-breathing short-axis scans in seconds and interactive interventional imaging with low latency. She concludes that real-time CMR could improve imaging for patients who cannot hold their breath, shorten clinical workflow, and reduce the need for general anesthesia in children.
