概括
年龄较大的大 (9岁以上) 不太可能使用非对比计算断层扫描 (CT) 准确诊断椎间盘挤出 (IVDE). 像CT骨髓图或MRI这样的高级成像通常需要在老年狗中进行明确的诊断.
科学领域:
- 兽医辐射学 兽医辐射学
- 狗神经学 狗神经学
背景情况:
- 椎间盘挤出 (IVDE) 是大犬中常见的一种神经疾病.
- 非对比计算断层扫描 (CT) 是IVDE的诊断工具,但其有效性可能因患者年龄而异.
研究的目的:
- 要确定患者的年龄是否会影响在使用非对比性CT时对大犬的压缩性椎间盘挤出 (IVDE) 诊断的准确性.
- 为了评估不同年龄组的犬的非对比CT的诊断性能.
主要方法:
- 对150只怀疑IVDE的犬进行了追溯分析.
- 对诊断成像 (CT,CT骨髓图,MRI) 和手术结果的评估.
- 在9岁以下的犬和9岁以上的犬之间,IVDE诊断率的比较.
主要成果:
- 9岁以下的狗有94.7%的IVDE诊断率与无对比CT.
- 9岁及以上的狗只有56%的IVDE诊断率与非对比CT,在44%的病例中需要先进的成像.
- 年龄显著增加了需要CT骨髓图或MRI的几率 IVDE诊断在老大 Dachshunds.
结论:
- 患者年龄是影响无对比CT在犬IVDE诊断准确性的重要因素.
- 较老的犬 (≥9岁) 更有可能需要CT骨髓图或MRI,因为IVDE在非对比CT上的可见性降低.
- 由于非对比CT限制,兽医应考虑为怀疑IVDE的老大犬提供先进的成像方法.

Degenerative Disc Disease I: Introduction
Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
Degenerative Disc Disease ll: Pathophysiology
The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...
