Canine stifle joint osteoarthritis (OA) is characterized by damage and degeneration of the articular cartilage and subchondral bone, bony hypertrophy at the margins, and synovial joint membrane changes. Non-invasive imaging modalities, such as digital radiography (DR), computed tomography (CT), and magnetic resonance imaging (MRI), can be used to describe these changes. However, the value of MRI in diagnosing spontaneous canine OA and the comparison of different imaging modalities have seldom been addressed. This study compared multiple noninvasive imaging modalities in canine spontaneous stifle OA cases. Four client-owned dogs with five spontaneously affected OA stifle joints were recruited and underwent DR, CT, and MRI. Information on osteophytes/enthesophytes, ligament/tendon lesions, synovial effusion and membrane thickening, subchondral bone lesions, and meniscal and cartilage lesions were scored and compared. The results showed that MRI provides the most comprehensive and superior lesion detection sensitivity for ligament, meniscus, cartilage, and synovial effusions. DR provides adequate bony structure information, while CT provides the most delicate images of bony structure lesions. These imaging findings may provide further understanding of the disease and help clinicians draft a more precise treatment plan.
犬膝关节骨关节炎（OA）的特征是关节软骨和软骨下骨的损伤与退变、边缘骨质增生以及滑膜关节膜改变。非侵入性成像方式，如数字X线摄影（DR）、计算机断层扫描（CT）和磁共振成像（MRI），可用于描述这些变化。然而，MRI在诊断自发性犬OA中的价值以及不同成像方式的比较很少被提及。本研究比较了犬自发性膝关节OA病例中的多种非侵入性成像方式。招募了4只客户拥有的患有5个自发性受累OA膝关节的犬，并对其进行了DR、CT和MRI检查。对骨赘/附着点骨赘、韧带/肌腱损伤、关节积液和滑膜增厚、软骨下骨损伤以及半月板和软骨损伤的信息进行评分并比较。结果表明，MRI对韧带、半月板、软骨和关节积液的病变检测敏感性最为全面和优越。DR可提供足够的骨质结构信息，而CT可提供骨质结构病变最精细的图像。这些成像结果可能有助于进一步了解该疾病，并帮助临床医生制定更精确的治疗方案。
