A total of 140 sets of abdominal radiographs were reviewed independently by four qualified diagnostic radiologists. The degree of interobserver agreement was determined by calculating kappa values for 19 commonly used radiographic signs and diagnoses. There was fair to excellent interobserver agreement for 11 signs and diagnoses and poor agreement for the remaining eight. The signs and diagnoses for which agreement is poor cannot be considered reliable and include particularly large bowel obstruction and nonspecific gas pattern.
四位合格的诊断放射科医生独立审查了总共140套腹部X光片。通过计算19种常用放射学征象和诊断的kappa值来确定观察者间的一致程度。11种征象和诊断的观察者间一致性为中等至优秀，其余8种的一致性较差。一致性较差的征象和诊断不可认为是可靠的，尤其包括大肠梗阻和非特异性气体模式。
