OBJECTIVE
Magnetic resonance imaging (MRI) was performed to evaluate soft tissue changes after nerve root and epidural injections in lumbar spine in patients with radiculopathy.
MATERIALS/METHODS: Patients underwent a multiple-shot injection protocol to nerve root/epidural space. The MRI protocol included T1-weighted, T2-weighted, STIR, and contrast-enhanced, fat-saturated T1-weighted sequences before and after treatment.
RESULTS
In all treated patients, a diffuse wedge-shaped edema in paravertebral tissues with a slight contrast enhancement was seen. Two small hematomas in the paravertebral muscle were noted. No changes in the epidural space, the abscess, or a lipodystrophy in epidural/nerve root space occurred.
CONCLUSION
Normal tissue changes after injection therapy of lumbar radiculopathy include wedge-shaped tissue edema at the injection level. In a minority of patients, small hematomas may occur.
目的
对患有神经根病的患者进行磁共振成像（MRI）检查，以评估腰椎神经根和硬膜外注射后的软组织变化。
材料/方法：患者接受了针对神经根/硬膜外间隙的多次注射方案。MRI方案包括治疗前后的T1加权、T2加权、短T1反转恢复序列（STIR）以及增强脂肪抑制T1加权序列。
结果
在所有接受治疗的患者中，可见椎旁组织出现弥漫性楔形水肿，并伴有轻微的对比增强。在椎旁肌肉中发现了两个小血肿。硬膜外间隙、脓肿或硬膜外/神经根间隙的脂肪营养不良均未发生变化。
结论
腰椎神经根病注射治疗后的正常组织变化包括注射部位的楔形组织水肿。少数患者可能会出现小血肿。
