METHODS: Prospectively, Pomeranians were included that underwent both CT and MRI studies of the head and cervicothoracic vertebral column. For those cases where qualitative classifications differed between observers, the experienced observer re-evaluated the studies and decided on a final classification that was used for further analysis. For quantitative measurements, the means of the observers\' measurements were used for analysis.
RESULTS: Among statistically significant differences in measurements, we found that dogs with SM had a significantly shorter clivus length based on both MRI (p = 0.01) and CT measurements (p = 0.01), and a significantly smaller caudal cranial fossa area based on both MRI (p = 0.02) and CT measurements (p = 0.02).
CONCLUSIONS: Significant morphometrical differences were identified between dogs with or without CM/SM. The findings in this study add to those already described in other breeds and provide further insight into factors that may play a role in the pathogenesis of CM/SM in Pomeranians.
方法:前瞻性,包括Pomeranians,他们对头部和颈胸脊柱进行了CT和MRI研究。对于观察者之间定性分类不同的情况,有经验的观察者重新评估了研究,并决定了用于进一步分析的最终分类.对于定量测量,观察者的测量值用于分析。
结果:在测量结果的统计学显着差异中,根据MRI(p=0.01)和CT测量(p=0.01),我们发现SM犬的斜坡长度明显较短,根据MRI(p=0.02)和CT测量(p=0.02),尾颅窝面积明显较小。
结论:在有或没有CM/SM的狗之间发现了显着的形态统计学差异。这项研究的发现增加了其他品种中已经描述的发现,并提供了对可能在波美拉尼亚CM/SM发病机理中起作用的因素的进一步见解。
