Motion correction algorithm improves right coronary artery image quality at heart rates > 75 bpm in non-ECG-gated coronary CT angiography.
Article in Journal of applied clinical medical physics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMotion artifacts caused by cardiac pulsation remain a major technical challenge in coronary CT angiography (CCTA). Although an advanced cardiac motion correction (CMC) algorithm has been developed and successfully implemented in clinical practice, the effectiveness of this algorithm in improving coronary image quality in clinical settings has not yet been fully investigated. PURPOSE: To evaluate the impact and clinical value of a motion correction algorithm on image quality in non-ECG-gated CCTA.
methodsWe retrospectively enrolled 76 patients who underwent CCTA for suspected coronary artery disease. Based on the mean heart rate (HR) recorded during scanning, patients were divided into three groups: low HR (HR ≤ 60 bpm), intermediate HR (60 < HR < 75 bpm), and high HR (HR ≥ 75 bpm). All images were reconstructed using both standard algorithm (STD) and CMC algorithms. The performance of STD and CMC was compared across different HR conditions in terms of subjective (4-point Likert scale, interpretability) and objective image quality (signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and vessel sharpness).
resultsAt high HRs, the difference in subjective image quality of the right coronary artery (RCA) between STD and CMC reached statistical significance (p < 0.05). Compared with STD, CMC significantly improved the interpretability of the RCA at high HRs (p < 0.001). No statistically significant differences were observed between the two algorithms in terms of SNR or CNR (p > 0.05). However, at high HRs, CMC was significantly superior to STD with respect to vessel sharpness of the RCA (p < 0.001).
conclusionsThe CMC improves image quality in CCTA, with particularly notable benefits for the RCA under high HR conditions.
