Sacroiliac joint (SIJ) disease has been described as one of the possible causes of lumbosacral (LS) region pain in dogs. However, published information is currently lacking for the computed tomographic (CT) and magnetic resonance imaging (MRI) characteristics of canine SIJ disease. The objectives of this retrospective, observational study were to describe and quantify CT and MRI SIJ findings in a sample of large breed dogs and test associations between the numbers of SIJ findings and other variables. Data archives for a veterinary teaching hospital were searched for large breed dogs (≥ 22.7 kg) that had CT or MRI scans of the LS and pelvic regions in 2015-2019. Dogs with a history of acute trauma or scans with incomplete SIJs were excluded. A veterinary student recorded medical record findings. A veterinary radiologist and graduate student recorded CT and MRI findings based on previously published criteria in dogs and humans. Fifty-three dogs were sampled (20 CT, 33 MRI). Categories of findings with the highest prevalence were subchondral erosion (100% CT, 100% MRI) and subchondral sclerosis (95% CT, 97% MRI). The total numbers of SIJ findings per dog were not associated with dog age, sex, weight, or concurrent findings in the LS or pelvic regions. The total number of MRI SIJ findings per dog differed between German Shepherds and Labrador Retrievers (P = 0.0237) as well as between Labrador Retrievers and other breeds (P = 0.0414). These results indicated that CT and MRI findings reported in humans with SIJ disease are common in large breed dogs.
骶髂关节 (SIJ) 疾病已被描述为犬腰骶部 (LS) 区域疼痛的可能原因之一。然而，目前缺乏有关犬 SIJ 疾病的计算机断层扫描 (CT) 和磁共振成像 (MRI) 特征的相关信息。本回顾性观察研究的目的是描述和量化大量品种犬样本中的 CT 和 MRI SIJ 发现，并检验 SIJ 发现数量与其他变量之间的相关性。对一家兽医教学医院的数据库进行了检索，以寻找在 2015 年至 2019 年间接受过 LS 和骨盆区域 CT 或 MRI 扫描的大型犬（≥22.7kg）。患有急性创伤史或扫描中 SIJ 不完整的犬被排除在外。一名兽医学生记录了病历发现。一名兽医放射科医生和研究生根据先前在犬和人类中发表的标准记录了 CT 和 MRI 发现。共采集了 53 只犬（20 只 CT，33 只 MRI）。发病率最高的发现类别是软骨下侵蚀（100% CT，100% MRI）和软骨下硬化（95% CT，97% MRI）。每只犬的 SIJ 总发现数量与犬的年龄、性别、体重或 LS 或骨盆区域的并发发现无关。每只犬的 MRI SIJ 总发现数量在德国牧羊犬和拉布拉多猎犬之间存在差异（P=0.0237），以及拉布拉多猎犬和其他品种之间存在差异（P=0.0414）。这些结果表明，在人类 SIJ 疾病中报告的 CT 和 MRI 发现也常见于大型犬种。
