Technologist Track: Advances in CMR-Rapid Development of CMR! CMR of the Future

Rapid Development of CMR! CMR of the Future

Video Transcription

Video Summary

The speaker describes how conventional cardiovascular MRI is slow, complex, and labor-intensive, requiring many clicks, EKG setup, breath-holds, navigators, and careful scan planning. He proposes a “free-running” approach that continuously acquires data without triggering or gating, using golden-angle radial sampling. Motion is then handled retrospectively with self-gating signals and compressed sensing reconstruction. This enables flexible post-processing for anatomy, function, coronary imaging, and flow studies, including pediatric and congenital heart disease cases. The approach improves efficiency, reduces patient burden, and may expand to future multidimensional imaging such as contrast, arrhythmia, and T1 mapping.
