Abstract

Background: Autopsy imaging (Ai) is used to determine the cause of death, providing pre-dissection information. Ai is often used in the field of human forensic medicine but has never been applied on farm animals.

Methods: Ai-computed tomography (CT) was performed before necropsy for farm animals (one goat, one ox, one cow and three calves) that died or were euthanised.

Results: Ai-CT findings of rib fractures (case 1), urethral calculi (case 2), multiple osteolytic bone lesions (case 3 and 4) and hair balls (case 4) were confirmed by dissection. However, a tentative diagnosis of actinomycosis was made in an ox (case 5) using antemortem radiography and Ai-CT, and the mass was identified as ameloblastic fibro-odontoma on histological examination. A tentative diagnosis of maxillary abscess was made from antemortem radiography in a cow (case 6); however, the lesion was shown to be maxillary neoplasia on Ai-CT. The mass was identified as hemangiosarcoma on histopathological examination.

Conclusion: Ai is helpful in pathological examination because the specific findings are known before the dissection, the lesions can be pinpointed in the pathological dissection, facilitating workflow; furthermore, the oversight of lesions can be reduced. In addition, Ai-CT images, including three-dimensional images and a three-dimensional printed model, allowed an easy understanding of pathology among students and farmers. Ai-CT for farm animals represents a novel option for veterinary education.

解剖成像-计算机断层扫描在农场动物死后研究中的作用。
背景:解剖成像(Ai)用于确定死因,提供解剖前的信息。Ai 常用于人类法医学领域,但从未应用于农场动物:方法:对死亡或安乐死的农场动物(一只山羊、一头黄牛、一头奶牛和三头小牛)进行尸体解剖前的 Ai 计算机断层扫描(CT):解剖证实了 Ai-CT 发现的肋骨骨折(病例 1)、尿道结石(病例 2)、多发性溶骨性骨病变(病例 3 和 4)和毛球(病例 4)。然而,一头牛(病例 5)通过死前放射摄影和 Ai-CT 被初步诊断为放线菌病,肿块在组织学检查中被确定为成髓性纤维牙瘤。根据一头牛(病例 6)的死前放射影像学检查,初步诊断为上颌骨脓肿;然而,Ai-CT 显示病变为上颌骨肿瘤。组织病理学检查发现肿块为血管肉瘤:结论:Ai 对病理检查很有帮助,因为在解剖前就能知道具体的检查结果,在病理解剖时就能准确定位病变,方便工作流程;此外,还能减少病变的疏忽。此外,Ai-CT 图像(包括三维图像和三维打印模型)使学生和养殖户更容易理解病理学。农场动物的 Ai-CT 是兽医教育的新选择。
