目的研究DR和CR的WNCR应用价值。方法从摄影、诊断及辐射防护角度对急诊、ICU(病房)及婴幼儿WNCR进行评价。结果摄影规模,DR大中连续,CR中小断续;单次检查显像出片用时,DR短,集体显像出片用时DR长;电量DR小;首次摄影成功率DR高;首次摄影失败原因,患者不完全配合居首位,位置不当和呼吸运动伪影居次,条件不当居三。DR中ICU比重大,CR急诊比重大,婴幼儿摄影是WNCR特殊点;DR甲级片比例高。ICU患者和协助家属、部分急诊和手术中患者、婴幼儿无防护。结论 WNCR临床效果满意,部分患者无防护。总评估,DR优于CR。
Objective To study the value of WNCR in DR and CR. Methods The emergency, ICU (Ward) and infant WNCR were evaluated from the perspectives of photography, diagnosis and radiation protection. Results: The scale of photography, DR large and medium continuous, small and medium-sized CR intermittent; a single examination shows the use of film, DR is short, the collective use of DR when the film was long; power DR small; first photography success rate DR high; , The patient does not fully cooperate with the first place, inappropriate location and respiratory motion artifact second, inadvertently living in three. DR in the proportion of ICU, CR emergency a large proportion of infants photography is a special WNCR point; DR A high proportion of films. ICU patients and assist families, some emergency and surgery patients, infants and young children without protection. Conclusion WNCR clinical results are satisfactory, some patients without protection. Overall, DR is better than CR.
