摘　　要：目的 :探讨不同特质病例数字化X线摄影(digital radiography,DR)废片率,为之后的质量控制提供依据。方法:分析影像归档和通信系统(picture archiving and communication systems,PACS)中98 503例病例DR影像的废片率,将病例依据性别、年龄、X线投射方向和受检者体位等不同特质分组,比较不同组别病例之间废片率的差异和废片产生原因的差异。结果:98 503例病例的DR废片率为4.89%,废片产生原因有摆位不正、异物伪影、移动伪影、机器问题和剂量不正确。性别、年龄和X线投摄方向对废片率产生有影响,而受检者体位对废片率产生无影响。结论:分析不同特质病例的废片率可以为之后开展降低DR废片率的质量管理工作提供依据。Objective To evaluate the causes of DR waste film rates in different characteristic cases, and provide basis for quality control. Methods DR waste film rates of 98 503 cases from PACS were analyzed. All cases were grouped according to gender, age, X ray projection direction and projection position. The differences of DR waste film rates between the groups were compared. Results DR waste film rate in 98 503 cases was 4.89% and factors that caused waste film were incorrect position, foreign materials, motion artifacts, machine problems and inappropriate X ray dosage. DR waste film rate was affected by gender, age, X ray projection direction, but not affected by projection position. Conclusion Analysis of DR waste film rate in different characteristic cases could provide basis for the quality control to reduce the DR waste film rate.
