In the past 12 months, 305 cases (male : female = 188 : 117; age = 1 days ~ 71-year-8-month) with CHD were analyzed. All MDCT images were taken at the end-diastolic phase of the cardiac cycle with intravenous injection of iodinated contrast medium. 3D reconstructed EBCT pictures were created with gradient shading surface rendering. In compare to the electron beam computed tomography, MDCT is reliable to well delineate the hypoplastic pulmonary artery, anomalous drainage of the pulmonary vein, where or not the presence of the pulmonary venous obstruction, abnormal branching of the coronary artery, associated tracheobronchial anomalies and stenosis, abnormal intra-cardiac and adjacent unusual three-dimensional spatial relationship. By adding the capability of three-dimensional demonstration and virtual reality cardioscopy, MDCT could show the extremely complex CHD completely and vividly. |
