目的通过调查与分析急诊CT检查阳性率,浅析医疗照射中放射实践正当化。提醒临床医生加强对X射线的认识,减少受检者不必要的照射,避免影响公众健康和安全。方法统计2008年我院急诊CT的阳性率,按照国家卫生部《综合医院分级管理标准(试行草案)》评定大型医疗设备检查阳性率要求,合理评价急诊CT检查的正当化。结果 16 804例急诊患者阳性率为34.9%,其中颅脑检查阳性率为31.8%,胸部检查阳性率为78.4%,腹部检查阳性率为33.6%,椎体椎间盘检查阳性率为76.7%,其他部位检查阳性率为53.6%,远未达到卫生部阳性率>60%要求。结论医疗照射目前已成为人类接受X射线最大的来源,而CT检查辐射剂量更大,必需要有相应的适应症,CT检查方可实施。
Objective To investigate and analyze the positive rate of emergency CT examination and analyze the radiation practice in medical radiation. Remind clinicians to strengthen their understanding of X-rays, reduce unnecessary exposure of subjects, and avoid affecting public health and safety. Methods The positive rate of CT in emergency department in our hospital in 2008 was calculated. The positive rate of positive examination of large medical equipment was assessed in accordance with the “General Hospital Grading Management Standard (Trial Draft)” of the Ministry of Health to reasonably evaluate the legitimacy of emergency CT. Results The positive rate of 16 804 emergency patients was 34.9%. The positive rate of craniocerebral examination was 31.8%, the positive rate of chest examination was 78.4%, the positive rate of abdominal examination was 33.6%, the positive rate of vertebral disc examination was 76.7% Check the positive rate was 53.6%, far less than the Ministry of Health positive rate> 60% of the request. Conclusion Medical radiation has become the largest source of human X-ray radiation. CT radiation dose is larger, and corresponding indications are necessary. The CT examination can be implemented.
