3D echocardiography (3DE) is evaluated as a readily available follow-up examination after Cardiac MR (CMR). Literature showed it underestimates LV volumes and is more variable. This study investigates the intrinsic reproducibility of both CMR and 3DE by repeatedly analyzing multiple datasets of two healthy volunteers with several software packages. Also, 20 patients were examined in a similar manner. LV volumes were larger with CMR than with 3DE, and although the CMR packages provided more reproducible results, 3DE analysis provides a valuable assessment of cardiac function.
