常规随访磁共振成像（MRI-2）在接受椎间盘脊柱炎治疗的无症状犬中的有用性尚不清楚。这项横断面回顾性研究调查了接受椎间盘脊柱炎治疗的异质性犬组的MRI-2特征，以及这些特征是否与临床体征的存在或不存在相关。在比较初始MRI（MRI-1）和MRI-2后，对犬临床体征设盲的观察者描述了MRI-2结果。然后在MRI-2时将研究人群分为有症状或无症状。两个独立的观察者主观地将椎间盘脊柱炎分为活动性或非活动性。评价了重复性和观察者间一致性。共纳入25只犬。在MRI-2时，16只（64%）犬无症状，9只（36%）有症状。根据MRI-2，第一名和第二名观察者分别认为25只犬中有20只（80%）和18只（72%）患有活动性椎间盘脊椎炎。观察者间一致性为中等。没有MRI-2特征与临床状态相关。非活动性椎间盘脊椎炎的主观分类与无症状临床状态显著相关，但活动性椎间盘脊椎炎的分类在组间均匀分布。本研究未发现接受推定椎间盘脊柱炎治疗的犬的临床状态与MRI-2结果之间存在有意义的相关性。没有与临床状态相关的特定MRI-2特征。
The usefulness of routine follow-up Magnetic Resonance Imaging (MRI-2) in asymptomatic dogs treated for discospondylitis is unknown. This cross-sectional retrospective study investigated the features of MRI-2 in a heterogeneous group of dogs treated for discospondylitis, and if these were associated with the presence or absence of clinical signs. After comparing initial MRI (MRI-1) and MRI-2, an observer, blinded to the dog's clinical signs, described the MRI-2 findings. The study population was then divided into symptomatic or asymptomatic at the time of MRI-2. Two separate observers subjectively classified the discospondylitis as active or inactive. Repeatability and interobserver agreement were evaluated. A total of 25 dogs were included. At the time of MRI-2 16 (64%) dogs were asymptomatic and 9 (36%) were symptomatic. Based on MRI-2, 20 (80%) and 18 (72%) out of 25 dogs were considered to have active discospondylitis by the first and second observers, respectively. Interobserver agreement was moderate. No MRI-2 features were associated with the clinical status. The subjective classification of inactive discospondylitis was significantly associated with asymptomatic clinical status, but the classification of active discospondylitis was evenly distributed between groups. This study did not identify a meaningful association between the clinical status of dogs treated for presumptive discospondylitis and MRI-2 results. There were no specific MRI-2 features which were associated with the clinical status.
