摘　　要：目的本研究使用国产最新的高分辨率小型数字平板研究低剂量前提下优化新生儿胸片图像质量的可能性。方法前瞻性入组2020年6至10月在本院新生儿监护室怀疑肺部感染的63例患儿,年龄0~1月。其中28例新生儿(男16例,女12例)纳入实验组,35例新生儿(男24例,女11例)纳入对照组。使用奕瑞Mars1012V高分辨率小型数字平板和DRX 2530C数字平板板比较图像质量。结果主观评价中,两个观察者在实验组和对照组的主观评分没有统计学差异(0.749 vs.0.766),且两个观察者之间的一致性很好(Kappa=0.86 vs.Kappa=0.82)。客观评价中,ROI_(空气),ROI_(气道),ROI_(胸椎)在两组之间没有统计学差异。在ROI_(软组织),ROI_(左肺),ROI_(右肺),实验组的信噪比和对比噪声比都优于对照组,差异有统计学意义(P<0.001)。结论控制辐射剂量的前提下,高分辨率小型数字平板可有效提高新生儿床边数字X线的图像质量,并有广泛的推广和应用前景。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.
