Description
Meiqi Wang and five co-authors evaluate software that un-blurs the heart's most mobile artery in CT scans taken without heartbeat gating, in this 2026 study. Coronary CT angiography fights motion: the heart's own pulsing smears vessel images, worst in the right coronary artery and worst at fast heart rates. A cardiac motion correction algorithm exists, but its clinical payoff in ungated scans was unproven.
Seventy-six patients scanned for suspected coronary disease were split by heart rate. Every scan was rebuilt both standardly and with correction, then graded for interpretability, noise ratios, and vessel sharpness. At rates above seventy-five beats per minute, correction significantly improved how the right artery looked and read, and its sharpness clearly beat standard rebuilding. Noise measures did not change. The authors conclude correction earns its keep precisely where the problem is hardest: fast hearts.
