Time-resolved MR angiography allows determination of cardiopulmonary transit times that are significantly prolonged in heart failure and correlate directly with LV volumes and inversely with LV ejection fraction.

Although further investigation is warranted, MRI may prove uniquely helpful in heart failure diagnosis and management.
