目的 :探讨准高kV摄影技术对床边胸部摄影的临床应用价值。方法 :采用西门子 2 5 0mA床边X线机 ,Agfa感蓝片 ,自动冲片机冲片 ,对 12 0例床边胸部影像质量及病变显示特点进行分析。结果 :12 0例准高kV床边胸片甲级片 10 2例 (占85 .0 % ) ,乙级片 11例 (占 9.2 % ) ,丙级片 7例 (5 .8% ) ,无废片。结论 :准高kV摄影技术能明显提高床边胸部影像甲片率 ,减低病人的辐射量 ,提高床边X线机的使用范围 ,为疾病诊断提供更多的影像信息
Objective: To investigate the clinical value of sub-high kV photography in chest radiography. Methods: The bedside chest image quality and lesion characteristics of 120 cases were analyzed by Siemens 250mA X-ray machine, Agfa blue film and automatic punching machine. Results: A total of 10 2 cases (85.0%) of the 100 cases were classified as quasi-high kV bedside radiography, 11 cases (9.2%) of grade B and 7 cases (5.8%) of grade C, Waste film. Conclusion: Quasi-high kV photography can significantly improve the rate of bedside chest radiography, reduce the patient’s radiation, improve the use of bedside X-ray machine and provide more image information for disease diagnosis
