Multi-reader evaluation of real-time MRI of the actively moving wrist at 0.55 Tesla

We acquired real-time MRI of the actively moving wrist in humans utilizing a high-performance 0.55T system. Resulting images and associated static wrist scans were assessed by two expert readers blinded to acquisition parameters. Our results show that images acquired at a high temporal resolution of 12.6 ms per frame demonstrate minimal image degradation compared to images acquired at temporal resolution of 100 ms or higher, and enable improved characterization of wrist motion. These benefits support further studies to assess high-performance 0.55T systems for the evaluation of dynamic dysfunction of the wrist.
