Radiographs of the reticulum, the medical records and the surgical and post mortem findings for 151 cattle were evaluated, and the radiographic findings in animals which had no pathological changes in the cranioventral abdomen were compared with those in animals with traumatic reticuloperitonitis. Features that were found to be reliable in the diagnosis of the condition included atypically positioned foreign bodies, abnormal gas shadows in the region of the reticulum, and depressions in the cranioventral margin of the reticulum. In addition to the reticulum, the remainder of the cranioventral abdomen was also assessed radiographically. An accumulation of gas or a gas-fluid interface outside the gastrointestinal tract, and intra-abdominal masses were typical findings in cattle with traumatic reticuloperitonitis. Various parameters were used to determine the reliability of radiography of the reticulum in the diagnosis of the condition; its prevalence was 50 per cent, the sensitivity of the radiographic diagnosis was 76 per cent, the specificity was 93 per cent, the accuracy was 85 per cent, the positive predictive value was 92 per cent and the negative predictive value was 80 per cent.
对151头牛的网胃X光片、病历以及手术和尸检结果进行了评估，并将颅腹侧无病理变化动物的X光检查结果与创伤性网胃炎动物的结果进行了比较。发现对该病诊断可靠的特征包括异物位置异常、网胃区域异常气体阴影以及网胃颅腹侧边缘凹陷。除网胃外，还对颅腹侧腹部其余部分进行了X光检查。胃肠道外气体积聚或气液界面以及腹腔肿块是创伤性网胃炎牛的典型表现。使用各种参数来确定网胃X光检查对该病诊断的可靠性；其患病率为50%，X光诊断的敏感性为76%，特异性为93%，准确性为85%，阳性预测值为92%，阴性预测值为80%。
