Multi-detector computed tomography angiography (MDCTA) provides high-resolution images of the heart and its vasculature, allowing for accurate anatomical assessment, detection of complex cardiac morphology,

evaluation of coronary artery anatomy, and identification of extracardiac anomalies including the coronaries, pulmonary arteries, aorta, and pulmonary or systemic veins, and it delineates vessel walls and also displays the airway, mediastinal abnormalities, and pulmonary parenchyma by using contrast media. This modality is particularly useful for evaluating complex cardiac anatomy and identifying potential surgical or interventional targets.
