目的：提出一种新的和实用的MRI分级方法颈椎神经孔狭窄，并评估其reproducibility.Methods：我们评估了50例（37名男性和13名女性，平均年龄49岁）谁访问了我们的机构，并进行斜矢状MRI的颈椎。对50例患者的300个椎间孔及相应的神经根进行了定性分析，从C4-5到C6-7。我们根据基于T-2加权斜矢状位图像的新分级系统，在最大狭窄点评估颈椎椎间孔狭窄的分级。通过卡方检验分析根据颈椎水平的神经孔狭窄等级的发生率。使用kappa统计分析两名放射科医生之间的观察者内和观察者间的一致性。Kappa值解释较差（Kappa
Objective: To propose a new and practical MRI grading method for cervical neural foraminal stenosis and to evaluate its reproducibility.Methods: We evaluated 50 patients (37 males and 13 females, mean age 49 years) who visited our institution and underwent oblique sagittal MRI of the cervical spine. A total of 300 foramina and corresponding nerve roots in 50 patients were qualitatively analysed from C4-5 to C6-7. We assessed the grade of cervical foraminal stenosis at the maximal narrowing point according to the new grading system based on T-2 weighted oblique sagittal images. The incidence of each of the neural foraminal stenosis grades according to the cervical level was analysed by chi(2) tests. Intra-and interobserver agreements between two radiologists were analysed using kappa statistics. Kappa value interpretations were poor (kappa
