The clinical accuracy and reproducibility of a new multi-contrast delayed enhancement (MCDE) sequence was tested in 41 patients. MCDE can be used to simultaneously visualize cardiac wall motion and viability; MCDE showed excellent agreement with the conventional wall motion and delayed enhancement sequences in this study. MCDE provides improved visualization of small infarcts and halves the number of breath-holds required wall motion and viability imaging.
