To determine the supraspinatus tendon volume using magnetic resonance imaging (MRI) in dogs with non-calcified supraspinatus tendinopathy (NCST), in dogs with orthopedic disease other than NCST, and in healthy dogs.
Case series.
Twenty-two dogs (18 client-owned dogs; 4 purpose-bred dogs).
Dogs undergoing shoulder MRI were categorized as NCST if they were diagnosed with NCST only, had histologic confirmed diagnosis, underwent surgical treatment, and were available for follow-up longer than 4 months. Dogs with MRI performed for a forelimb lameness because of a diagnosis other than NCST were categorized as orthopedic control (OC). Healthy dogs from an unrelated study were categorized as healthy controls (HC). Tendon volume was determined from MRI using public domain software and compared across categories.
The study included 9 NCST dogs, 9 OC dogs, and 4 HC dogs. The median tendon volume for NCST was 1,323 mm(3), OC was 630 mm(3), and HC was 512 mm(3). The volume was significantly higher in the NCST than OC (P = .0012) and HC (P = .003). There was no difference between OC and HC (P = .76).
Dogs diagnosed with NCST had higher supraspinatus tendon volumes compared to dogs with other orthopedic disorders and healthy dogs.
使用磁共振成像（MRI）测定非钙化性冈上肌腱病（NCST）犬、患有除NCST外的其他骨科疾病的犬以及健康犬的冈上肌腱体积。
病例系列。
22只犬（18只客户拥有的犬；4只专门繁育的犬）。
接受肩部MRI检查的犬，若仅被诊断为NCST、经组织学确诊、接受了手术治疗且随访时间超过4个月，则被归类为NCST。因除NCST外的其他诊断而进行MRI检查以评估前肢跛行的犬被归类为骨科对照（OC）。来自一项不相关研究的健康犬被归类为健康对照（HC）。使用公共领域软件从MRI图像中确定肌腱体积，并在各分类之间进行比较。
该研究包括9只NCST犬、9只OC犬和4只HC犬。NCST犬的肌腱体积中位数为1323立方毫米，OC犬为630立方毫米，HC犬为512立方毫米。NCST犬的肌腱体积显著高于OC犬（P = 0.0012）和HC犬（P = 0.003）。OC犬和HC犬之间无差异（P = 0.76）。
与患有其他骨科疾病的犬和健康犬相比，被诊断为NCST的犬冈上肌腱体积更大。
