Full free-breathing motion-corrected cardiac cine and late gadolinium enhancement MRI: feasibility and validation in clinical practice.

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
To validate the use of full free-breathing (FB) motion-corrected (MoCo) cardiac MRI examinations in assessing biventricular systolic function and tissue characterization compared with the reference standard breath-hold (BH) examination. In this prospective study, 216 patients underwent 3-T cardiac MRI. Of these patients, 113 underwent FB motion-corrected cardiac cine imaging in addition to standard BH cine imaging; the remaining 103 patients underwent FB motion-corrected late gadolinium enhancement (LGE) imaging in addition to standard BH LGE imaging. Image quality was assessed with a five-point scale (1 = nondiagnostic, 5 = very good). Left ventricular (LV) and right ventricular (RV) functional parameters and LGE mass in BH and FB examinations were analyzed using Wilcoxon signed-rank test, Bland-Altman plots, and linear regression. Subjective image quality between the FB and BH groups was comparable for cine imaging (4.02 ± 0.81 vs. 4.14 ± 0.79, P = 0.220) but was significantly better in the FB group for LGE (4.79 ± 0.46 vs. 4.16 ± 0.79, P < 0.001). Scan times for both cine (149.46 ± 32.29 s vs. 392.61 ± 47.02 s, P < 0.001) and LGE (198.12 ± 41.90 s vs. 361.69 ± 46.17 s, P < 0.001) were consistently shorter in the FB group than in the BH group. No significant differences were found in biventricular volumetric parameters or LGE mass measurements between FB and BH groups. Bland-Altman plots and linear regression analysis showed good agreement for LV and RV functional parameters and LGE mass in BH and FB sequences. Full FB cardiac MRI produces high-quality images and could be a suitable alternative for patients who cannot tolerate multiple BHs or long examination times.
