Abstract:Objective To optimize the image quality of neonatal chest X-ray using the latest high-resolution small digital tablet.
Methods A total of 63 children with suspected pulmonary infection in the neonatal intensive care unit of our hospital from June to
October in 2020 were prospectively enrolled (aged 0-1 month). Among them, 28 newborns (16 males and 12 females)were included
in the test group, and 35 newborns (24 males and 11 females) were included in the control group. The image quality was compared
between AIRRAY Mars1012V high resolution small digital flat panel and DRX 2530C digital imaging plate system. Results In the
subjective evaluation, there was no significant difference in the subjective scores between the two observers in the test group and the
control group (0.749 vs. 0.766), and the consistency between the two observers was good (Kappa=0.86 vs. Kappa=0.82). In objective
evaluation, there was no significant difference in ROI (air, airway and thoracic vertebrae) between the two groups. In ROI soft tissue, ROI
left lung and ROI right lung, the signal-to-noise ratio and contrast noise ratio of the experimental group were better than those of the control
group, with significant differences (P<0.001). Conclusion Under the premise of radiation dose control, high-resolution small digital
plate can effectively improve the image quality of newborn bedside digital X-ray and has a wide range of promotion and application
prospects.
