概括
像T2映射这样的定量MRI参数可以帮助识别椎间盘 (IVD) 退化,这是腰部疼痛 (LBP) 的常见原因. 这些成像技术可能为诊断LBP原因提供新的途径.
科学领域:
- 放射学 放射学是一门学科.
- 整形外科 整形外科 整形外科
- 生物医学成像技术 生物医学成像技术
背景情况:
- 腰部疼痛 (LBP) 是一种普遍的疾病,通常与椎间盘 (IVD) 退化有关.
- 在IVD退化和LBP之间确切的病理生理联系仍然不清楚.
- 这项研究调查了定量磁共振成像 (MRI) 参数,以阐明这种关系.
研究的目的:
- 为了澄清量化MRI参数 (q-Dixon和T2映射) 与LBP患者的临床症状之间的相互作用.
- 评估特定的MRI指标与IVD退化和疼痛水平的严重程度的相关性.
主要方法:
- 腰椎MRI,包括q-Dixon和T2映射,在LBP患者身上进行.
- 疼痛的严重程度是使用奥斯威斯特残疾指数 (ODI) 评分来评估的.
- T2和T2*映射评估了前环纤维化 (AAF),核纤维化 (NP),后环纤维化 (PAF) 和脊髓骨髓脂肪分数 (BMFF),并通过统计分析将其与Pfirrmann等级和ODI得分相关联.
主要成果:
- 对95名LBP患者的分析显示,NP和Pfirrmann等级中的T2/T2*值之间存在显著的相关性 (r=-0.844,-0.704).
- 脊椎骨髓脂肪分数 (BMFF) 与Pfirrmann等级显示了中等相关性 (r=0.646).
- 特定的MRI参数 (AAF,NP,PAF的T2值;NP的T2*值;BMFF) 有效地区分了低,中度和严重的疼痛水平.
结论:
- 纤维环和脉核的定量T2和T2*值,以及脊髓骨髓脂肪分数,反映了椎间盘退化的程度.
- 这些MRI指标显示,有潜力对腰部疼痛的潜在原因进行定量评估.

Herniated Intervertebral Disc l: Introduction
40
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Degenerative Disc Disease I: Introduction
29
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
30
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...
