Fig. 3: Cross-modal autoencoders enable imputing cardiac MRIs from ECGs while capturing MRI-specific features such as left ventricular mass (LVM) and right ventricular end-diastolic volume (RVEDV) on test MRI–ECG pairs.

a Examples showing qualitatively that MRIs imputed from test ECG samples capture LVM for those individuals with LVM in the highest and lowest quartile. The LVM in the original, translated, and reconstructed MRI is shown in red. b Examples showing qualitatively that MRIs imputed from test ECGs capture RVEDV for those individuals with RVEDV in the highest and lowest quartile. The RVEDV in the original, translated, and reconstructed MRI is shown in red. c The predictions of LVM and RVEDV on MRIs imputed from test ECGs correlate with the predictions of these phenotypes performed on the original MRIs.
