概括

关于马脚MRI病理学评估的观察者间的共识很差,对船骨的共识中等. 经验丰富的观察员在感知病理严重程度上显示出差异,影响了临床解释.

科学领域:

兽医辐射学兽医辐射学
马匹诊断成像技术马匹诊断成像技术

背景情况:

关于马脚磁共振成像 (MRI) 病理评估和信心水平的观察者间协议没有得到充分记录.
准确的MRI解释对于诊断马足的疾病至关重要.

研究的目的:

评估使用MRI评估马足病理的观察者间一致性.
评估观察者对关键马足解剖结构的病理学分级的信心.

主要方法:

十名经验丰富的观察员在三个MRI系统中评估了15个马脚MRI研究.
病理和信心被评分,使用七个解剖结构的4分级.
使用弗莱斯的卡帕和肯德尔的一致系数分析了观察者间的一致性.

主要成果:

对病理存在/不存在的共识很差,除了 navicular 骨 (中等共识,k=0.52).
对于病理学分级的相对一致性各不相同 (KCC=0.19到0.70),在极端病理学级别的相对一致性更高.
观察者对评估的信心一般是中等到高的.

结论:

经验丰富的观察者在MRI上对马足病理严重程度的感知存在显著差异.
这种变异性,即使具有很高的置信度,对诊断和治疗规划具有临床影响.
对马足病理的MRI解释协议进一步标准化可能是有益的.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
