- Introduces a rapid, self-calibrated cardiac MRI framework for noninvasive quantification of myocardial oxygen consumption and efficiency within 3 minutes.
- Overcomes previous barriers like complex calibration, motion artifacts, and long acquisition times through motion-resolved coronary sinus oximetry.
- Validated against invasive coronary sinus catheterization in a porcine model and demonstrated feasibility in patients with and without heart failure.
- Holds potential for early disease detection, personalized therapy, and guiding cardiometabolic therapies to address heart failure.
