Congenital heart disease (CHD) is the most commonly occurring congenital anomaly, affecting 4-10/1000 live births. Neonatal congenital heart disease is the most difficult area of diagnostic radiology because of the small body size, unstable vital signs, and the difficulty in adjusting radiation dose and scanning parameters[1]. Over the past few decades, advances in diagnostic techniques and surgical management have greatly improved patient survival, with around 90% of patients with CHD reaching adulthood [2]. Complex cases of CHD present with multiple malformations, and require accurate preoperative...

In our institution from 2007 to December 2018 the MDCT was performed annually in up to 400 cases of neonates with CHD. CT scans were taken in all patients using a Somatom Sensation Cardiac 16 until 2016, Somatom definition AS+ in 2016 and 2017, and then Somatom Definition Edge in 2018 (Siemens AG, Forchheim, Germany). The thorax is a low-attenuation region, although substantial dose reduction during chest CT is feasible because of the high inherent contrast. In our centre, we decided to apply the ALARA...

The advent of MDCT, which can afford fast scanning times, increased anatomic coverage, and high-quality 2D and 3D reconstructions, has revolutionized congenital heart disease imaging in neonates. Accurate diagnosis of CHD depends on understanding of optimal MDCT technique, postprocessing imaging technique, and characteristic CT imaging appearance of these lesions as well as associated abnormalities. Using this protocol, radiation exposure is estimated below 1mSv for a neonate.
