对3具尸体脊柱、40例有腰椎间盘疾病症状的患者和10例健康人进行了MR检查。T2加权自旋回波图像用于评价核内裂的特征。在T2加权像和组织学上，该裂隙与瓣环组织相同。采用120 ms TE、3 s TR图像从纤维环中划分正常髓核。计算唇腭裂的发病率和年龄分布。在30岁及以上的对照组和有症状的受试者中，所有正常椎间盘均存在核内裂。如果存在于1个椎间盘中，则其也存在于同一受试者94%的其他椎间盘中。这种裂隙代表了正常的解剖结构，在30岁或以上的受试者中似乎是一个恒定的特征。在椎间盘内存在增加的信号强度的情况下，其缺失表明具有长T2值的病理过程，例如炎症。
Three cadaver spines, 40 patients who were symptomatic for lumbar disc disease and 10 healthy subjects were examined by MR. T2 weighted spin echo images were used to evaluate the character of an intranuclear cleft. This cleft appears identical to annular tissue both on T2 weighted images and histologically. A 120 ms TE, 3 s TR image was used to delimit the normal nucleus pulposus from the annulus. The incidence and age distribution of the cleft were calculated. An intranuclear cleft was present in all normal discs in both control and symptomatic subjects who were 30 yr of age and older. If present in 1 disk, it was also present in 94% of the other discs in the same subject. This cleft represents a normal anatomic structure and appears to be a constant feature in subjects 30 yr of age or older. Its absence, in the presence of an increased signal intensity within the disc, suggests a pathological process with a long T2 value, such as inflammation.
