目的：评估过屈位和过伸位核MRI对颈椎椎间盘突出症的诊断价值。方法对50例患者进行中立位、过屈位和过伸位颈椎MRI检查。利用计算机软件对各个节段颈椎间盘突出程度进行客观测量评估。结果在过伸位上，各节段颈椎椎间盘突出同中立位相比均有显著性增加（t＝2.05～5.05，P＜0.05）。在中立位正常或椎间盘突出＜3 mm，2.21%患者在过屈位椎间盘突出进展到＞3 mm，16.54%患者在过伸位椎间盘突出进展到＞3 mm。在中立位椎间盘突出＞3 mm且＜5 mm，3.57%患者在过屈位椎间盘突出进展到＞5 mm，10.71%患者在过伸位椎间盘突出进展到＞5 mm。结论与中立位相比，动力位 MRI 上颈椎椎间盘突出更加明显。动力位MRI对颈椎间盘突出症的评估有其独特价值，尤其是对那些有神经根症状而普通MRI无异常发现的患者。

Objective To determine if adding flexion and extension MRI studies to the traditional neutral views would be beneficial in the diagnosis of cervical disc herniations. Methods Fifty patients underwent MRI in neutral, flexional and extensional positions. The images were analyzed using computer software to objectively quantify the amount of disc herniation. Results Compared to neutral position, cervical disc herniations were significantly increased in extension MRI (P<0.05). For patients with normal or 3 mm of disc bulge in neutral, 2.21%demonstrated an increase in herniation to 3 mm bulge in flexion, and 16.54%demonstrated an increase to 3 mm bulge in extension. For patients in the neutral view that had a baseline disc bulge of 3 to 5 mm, 3.57%had increased herniations to 5mm in flexion and 10.71%had increased herniations to 5 mm in extension. Conclusion A significant increase in the degree of cervical disc herniation is found by examining flexion and extension views when compared with neutral views alone. Kinematic MRI views provide valuable added information, especially in situations where symptomatic radiculopathy is present without any abnormalities demonstrated on conventional MRI.
