Introduction. X‑ray examination (RTG) has a significant place in neonatal diagnostics. It is mostly performed for the evaluation of defects of the heart, lungs, diaphragmatic hernia, injuries and also to determine the location of foreign objects. The photo is done bedside with a transportable camera or a dynamic test is performed of the gastrointestinal tract using isotonic contrast agents. Aim. The aim of this study was to classify radiological tests performed on hospitalized neonates in the GPSK University of Medical Sciences in Poznan. Material and method. The analysis included data collected from medical records of 200 hospitalized newborns in the Neonatology Department of Gynaecology and Obstetrics at the Clinical Hospital University of Medical Sciences. We evaluated sex, weight, gestational age, Apgar score, type of birth, medical diagnosis. The evaluation of the correlation between the indicated parameters and executed X‑rays was performed using Microsoft Office and Excel 2007 programs. Results. Statistical analysis and descriptive showed that the most frequently performed diagnosis in the X‑ray group was transfontanellar ultrasound. The second most popular study was X‑ray radiograph of the chest and abdomen. Assessing the correlation, revealed that sex of the newborn has an impact on the type of radiological examination performed. It was noted that the birth, Apgar score, and presence of neonatal disease can also affect the type of diagnostic procedure. Conclusions. Neonatal diagnostic radiology is the second most commonly performed diagnostic method after ultrasound diagnostic test. It plays a special role in the diagnosis of congenital malformations in the newborn.
