Pictorial Review of Multidetector CT Imaging of the Preoperative Evaluation of Congenital Heart Disease

Sequential segmental approach is an efficient method for complete evaluation of complex congenital heart diseases (CHD). Although echocardiography is the imaging technique of choice, recent advances in computed tomography and cardiac magnetic resonance have given a new dimension to the traditional diagnostic assessment of CHD. CT has advantages of fast speed, higher spatial resolution, and simultaneous lung and airway visualization. The purpose of this pictorial review is to discuss the role of CT and emphasize its protocol and the segmental approach for comprehensive assessment of CHD.
