This study aimed to evaluate the application of radiography, ultrasonography, and computed tomography (CT) as auxiliaries in the determination of body fat and musculature in crab-eating foxes (Cerdocyon thous). Eight animals were evaluated and classified based on the body condition score (BCS) scale. The total cut volume, total visceral volume, total subcutaneous volume, visceral fat volume, subcutaneous fat volume, and total fat volume were measured. The correlation of the BCS with the other data was determined. In the ultrasound, there was a correlation of the vertebral epaxial musculature score (VEMS) with body weight, BCS, muscle mass score (MMS), animal's height, and height at the withers. In the radiographic analysis, the amount of subcutaneous fat obtained in L3 vertebrae did not present a significant correlation with BCS, as opposed to L6. In the tomographic analysis, TFV/L6, VFV/L6, and SFV/L6 correlated with BCS in L3, and only SFV /L6 in L6. When the ratios between fat volumes were correlated, the correlation with BCS occurred only in L6 in the TFV/TBV, SFV/SVC, and VFW variants. Radiography and CT were effective and had a good association with BCS. With the CT it was possible to demonstrate the distribution of total fat at the level of the L3 slice. The ratio of calculations considering the length of the L6 vertebra was more adequate, while at the level of L6 the ratio between the volumes of the compartments was more effective.
本研究旨在评估放射学、超声和计算机断层扫描（CT）在评估食蟹狐（Cerdocyon thous）体脂肪和肌肉量中的应用。对 8 只动物进行了评估，并根据体况评分（BCS）量表进行了分类。测量了总切割体积、总内脏体积、总皮下体积、内脏脂肪体积、皮下脂肪体积和总脂肪体积。确定了 BCS 与其他数据的相关性。在超声中，椎旁脊柱肌肉评分（VEMS）与体重、BCS、肌肉质量评分（MMS）、动物身高和肩高呈正相关。在放射学分析中，L3 椎骨处获得的皮下脂肪量与 BCS 无显著相关性，而与 L6 椎骨处的皮下脂肪量有显著相关性。在 CT 分析中，L3 处的 TFV/L6、VFV/L6 和 SFV/L6 与 BCS 相关，而 L6 处仅 SFV/L6 与 BCS 相关。当比较脂肪体积之间的比例与 BCS 的相关性时，仅在 L6 处观察到 TFV/TBV、SFV/SVC 和 VFW 变异体与 BCS 之间存在相关性。放射学和 CT 均有效，与 BCS 具有良好的相关性。使用 CT 可以在 L3 切片水平上显示总脂肪的分布。考虑 L6 椎骨长度的计算比值更合适，而在 L6 水平上，各腔室之间的体积比值更有效。
