VIDEO 236-6: A patient with severe aortic regurgitation quantified by cardiac magnetic resonance (CMR).

From: Harrison's Principles of Internal Medicine, 20e

Notice the dark flow jet during diastolic across the aortic valve. For quantitation of the aortic regurgitation severity, a cross-sectional cut was made just below the aortic valve, perpendicular to the aortic regurgitation jet, using phase contrast flow imaging. Apart from aortic regurgitation fraction and volume, CMR also can volumetrically quantify ventricular sizes and dimensions of the aorta, which are useful in monitoring patients with aortic valve diseases.
