MRI and CT

Cardiovascular MRI (CMR) is a useful tool in diagnosis and evaluation of bicuspid aortic valve. Stead-state free precession sequences are used to obtain a slice in the place of the valve, and show the anatomy of the valve well. Differentiation may be made between an anatomically bicuspid valve, and anatomically trileaflet valve with fused comissures ("functionally-bicuspid valve"). In addition, CMR is invaluable in defining anatomic valve area, in quantification of aortic regurgitation, and in diagnosis of concomitant cardiovascular abnormalities, such as thoracic aortic dilatation/aneurysm and mitral valve abnormalities.
