The lung volumes are typically small since its pathophysiology is essentially underinflated alveoli and microatelectasis. On chest radiographs, RDS show underaerated lungs with variable degrees of opacities from granular lungs to total white-out ( Fig. When the UVC is placed too high, it can reach even up to the pulmonary vein across the patent foramen ovale ( Fig. Malpositioned UVC tip increases complication rates such as venous thrombosis or hepatic parenchymal necrosis ( 3). The tip of UVC is proper when it is at the inferior vena cava and right atrium junction near the right hemidiaphragm. The localization of the tip of the UAC should be in avoidance of the major branches such as the arch vessels and renal arteries: high-type UAC in between T6 and T9 vertebral body levels and low-type at 元–4 level. After joining the left portal vein, the UVC goes up to the inferior vena cava through the ductus venosus and hepatic vein. On the other hand, the umbilical venous catheter (UVC) proceeds directly upward and then enters the left portal vein at the umbilical portion. So, the UAC always shows a hairpin turn below the umbilicus. The umbilical arterial catheter (UAC) goes downwardly first and then upwardly via the internal iliac artery and common iliac artery before entering the aorta ( Fig. The central venous catheter is considered optimal with its tip position in the region of the superior vena cava (or inferior vena cava) and right atrium junction. Tube position is affected by neck flexion or rotation. The endotracheal tube should be positioned in the middle of the clavicles and carina level, which is approximately 2 cm above the carina. Various tubes and catheters are seen on plain radiographs and determining whether their position is optimal or not is important to avoid serious complications. Keywords: Infant, Newborn, Radiography, Thoracic, Respiratory Distress Syndrome, Newborn The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions.

Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates.
