TC, translational motion corrected; NRC, combined translational and non-rigid motion corrected; FWHM, full width at half maximum. Overall image quality scores: 5 = excellent image quality, interpretable with no artifacts; 4 = good image quality, interpretable with minimal artifacts; 3 = average image quality, interpretation mildly degraded by image artifacts; 2 = below average image quality, interpretable but moderately degraded; 1 = poor image quality, uninterpretable images. Anatomical details, sharpness, chest wall scores: 5 = excellent, 4 = good, 3 = average, 2 = below average, 1 = poor. Most data are not normally distributed or ordinal level, so median, range, and interquartile range (IQR) are provided for better comparability
