Extraction of cardiac and respiratory motion from Pilot Tone—a patient study

Video Transcription

Video Summary

The study evaluated Peloton navigator data for extracting respiratory and cardiac motion in 23 cardiac MRI patients. Respiratory signals from Peloton correlated better with real-time imaging reference than standard biometric respiratory sensors. For cardiac motion, Peloton-derived triggers compared favorably with ECG, showing fewer false triggers overall, though trigger delay varied by patient. Some cases required additional tuning, and arrhythmia or other motion sources caused false triggers. The authors conclude Peloton is a promising tool for patient cardiac MRI motion monitoring and plan to apply it to additional CMR techniques.
