Three Key Takeaways
- Improved accuracy. Photon-counting CT (PCCT) demonstrated substantially stronger correlation with CMR for myocardial ECV quantification compared to energy-integrating detector CT (EID-CT).
- Better performance in patients with higher heart rates. PCCT maintained higher reliability than EID-CT in patients with elevated or irregular heart rates, reducing motion artifacts and improving image quality.
- Lower radiation dose. PCCT provided more accurate myocardial tissue characterization at less than half the radiation dose of EID-CT, enhancing its clinical utility.
