This study involved 503 cattle with traumatic reticuloperitonitis (TRP), 494 of which underwent ultrasonographic and 484 radiographic examination of the reticulum. Ultrasonography revealed changes in the reticulum and/or peritoneum suggestive of peritonitis in 403 (83%) cattle, a decrease in the amplitude of reticular contractions in 244 (54%) and reduced or absent reticular motility in 173 (37%). A total of 536 foreign bodies were seen on 465 (96%) radiographs and a magnet was seen on 311 (64%) radiographs. Of the 536 foreign bodies, 300 (56%) were not attached to a magnet and 236 (44%) were attached. Of 300 radiographs showing foreign bodies not attached to a magnet, the foreign body was lying flat on the floor of the reticulum on 98 (18%) radiographs, was at an angle of greater than 30 degrees to the ventral aspect of the reticulum on 54 (10%), had penetrated the dorsal reticular wall on 76 (14%), had perforated the reticulum on 64 (12%) and was completely outside of the reticulum on 8 (1%) radiographs. Ultrasonography provides information about the scale and localisation of inflammatory changes of the peritoneum, and radiography allows the visualisation of ferromagnetic foreign bodies and magnets.
本研究涉及 503 头患有创伤性网胃腹膜炎（TRP）的牛，其中 494 头进行了网胃的超声和 484 头进行了射线照相检查。超声检查显示 403 头（83%）牛的网胃和/或腹膜有腹膜炎变化，244 头（54%）牛的网胃收缩幅度降低，173 头（37%）牛的网胃运动减少或消失。在 465 张射线照片中可见 536 个异物，在 311 张射线照片中可见磁铁。在 536 个异物中，有 300 个（56%）未附着在磁铁上，236 个（44%）附着在磁铁上。在 300 张显示未附着磁铁的异物的射线照片中，异物在 98 张（18%）射线照片中平躺在网胃底部，在 54 张（10%）射线照片中与网胃腹侧面的角度大于 30 度，在 76 张（14%）射线照片中穿透了网胃背侧壁，在 64 张（12%）射线照片中穿透了网胃，在 8 张（1%）射线照片中完全位于网胃之外。超声检查提供了关于腹膜炎炎症变化的范围和定位的信息，射线照相术允许可视化铁磁性异物和磁铁。
