目的探究移动数字化X射线摄影系统﹙床旁DR﹚于急危重症患者疾病诊断中的应用意义。方法收集行床旁DR检查的急危重症患者348例DR片,调整合适的窗宽窗位后,分别依据对比度、密度、清晰度、体位等进行分析、评价。结果甲级片144例(41.4%),乙级片193例(55.4%),丙级片11例(3.2%),没有废片;重拍7张(2.01%)。结论应用床旁DR可显著提升急危重患者床旁影像片质量,设备配备显示器,可即时成像,为诊疗争取宝贵时间;降低重拍几率,从而使患者所接受的辐射剂量有所减低。
Objective To explore the application of mobile digital radiography system (bedside DR) in the diagnosis of acute critically ill patients. Methods A total of 348 DR patients with acute critically ill patients who were examined by bedside DR were collected. The appropriate window widths and windows were adjusted and analyzed according to contrast, density, sharpness and position respectively. Results There were 144 cases (41.4%) of Grade A, 193 cases (55.4%) of Grade B and 11 cases (3.2%) of Grade C, with 7 pieces (2.01%) remade. Conclusion The application of bedside DR can significantly improve the quality of bedside radiographs in critically ill patients. The equipment is equipped with a monitor and can be used for imaging instantaneously, thus obtaining valuable time for diagnosis and treatment and reducing the chance of remapping so that the radiation dose received by the patient is reduced.
