The purpose of this study is to describe the normal findings of the newborn chest radiography, the criteria utilized for evaluating the quality radiographs and the correct catheter and tube positions, emphasizing the peculiarities inherent to the patient's age. In the neonatal period changes in the fetal circulation contribute to an increase in cardiac size, skin folds and variations in the thymic silhouette may simulate diseases, the evaluation of catheter and tube positions avoids iatrogenic complications, the abdominal gas pattern must be correlated with the patient's age and the presence of the secondary ossifications centers in the upper humerus and scapula is associated with the term newborn, providing a radiological sign for normal skeletal maturation. The knowledge of the peculiarities and normal radiological findings of the newborn chest radiography avoids ambiguous diagnosis, reduces iatrogenic complications and represents a valuable support in the diagnosis and clinical follow-up of these patients.
