概括
超声波 (US) 和计算机断层扫描 (CT) 显示出对评估马的胸脊关节过程关节 (APJ) 周关节建模的良好一致性,特别是在尾部区域. 这支持诊断超声波来评估马背部疼痛.
科学领域:
- 兽医诊断成像 - - 兽医诊断成像
- 马类骨科 马类骨科 马类骨科
- 比较解剖学的比较解剖学.
背景情况:
- 马胸关节过程关节 (APJs) 的骨关节炎是背部疼痛的常见原因.
- 目前的诊断方法包括核光学,放射学和超声学 (美国).
- 与计算机断层扫描 (CT) 相比,美国对APJ评估的可靠性需要进一步调查.
研究的目的:
- 评估US和CT之间的协议,以分类马匹胸脊柱骨关节炎.
- 确定APJ的位置是否会影响US和CT等级之间的协议.
- 为了测试假设,周关节模型显示的一致性比关节空间修改更高,尾部APJ有更好的一致性.
主要方法:
- 一个比较的诊断成像研究,利用尸体马的胸脊椎.
- 对APJ进行了US和CT检查,评估了周关节建模,关节空间修改和扩大.
- 采用多级加权的kappa统计数据来评估观察者内部,观察者间和模式间的协议,考虑位置和成像特征.
主要成果:
- 对于US和CT分级,观察者内部中等到完美的一致性被观察到.
- 模式间协议 (CT与CT对比) 在T15-L1之间,对周关节建模的协议是中等的;对联合空间修改和扩展的协议是公平的.
- 实质性的观察者间协议 (美国与美国). 在尾部胸脊柱区域 (T15-L1) 进行了周关节建模.
结论:
- 在尾部胸脊柱APJ中进行周关节建模的良好观察者间和模式间协议支持使用诊断超声波.
- 美国评估的周关节建模反映了骨变化,验证了其在马背部疼痛诊断中的实用性.
- 宽的置信区间表明由于样本大小和患病率的限制,需要谨慎解释.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
