Additional file 5 of Association of right atrial structure with incident atrial fibrillation: a longitudinal cohort cardiovascular magnetic resonance study from the Multi-Ethnic Study of Atherosclerosis (MESA)

Additional file 5. Examples of images from sequences excluded from the study for poor quality. Each of these representative images are taken from excluded sequences at RA end-diastole. Each image is from a different study site and was labeled as the long-axis image for that participant. Evident in these images are motion artifact and planes which do not completely capture the RA. Such images were numerous in our analysis, resulting in the exclusion rate.
