Dual-energy computed tomography imaging in comprehensive assessment of truncus arteriosus in neonates: A case series

Truncus arteriosus (TA) is a rare congenital heart disease in which a single arterial trunk arises from the heart, providing systemic, coronary, or pulmonary circulation. This condition is frequently associated with ventricular septal defects and various other cardiac and pulmonary irregularities. In this case series, we described the radiological findings and the related cardiac and pulmonary complications in three neonates diagnosed with persistent TA (PTA). This series underscores the critical role of dual-energy computed tomography in the assessment of PTA and illustrates its utility in identifying associated anomalies, thereby enhancing comprehensive patient management.
