PURPOSE
Indicating lumbar disc herniation via magnetic resonance imaging (MRI) T2 mapping in the posterior annulus fibrosus (AF).
METHODS
Sagittal T2 maps of 313 lumbar discs of 64 patients with low back pain were acquired at 3.0 Tesla (3T). The discs were rated according to disc herniation and bulging. Region of interest (ROI) analysis was performed on median, sagittal T2 maps. T2 values of the AF, in the most posterior 10% (PAF-10) and 20% of the disc (PAF-20), were compared.
RESULTS
A significant increase in the T2 values of discs with herniations affecting the imaged area, compared to bulging discs and discs with lateral herniation, was shown in the PAF-10, where no association to the NP was apparent. The PAF-20 exhibited a moderate correlation to the nucleus pulposus (NP).
CONCLUSIONS
High T2 values in the PAF-10 suggest the presence of disc herniation (DH). The results indicate that T2 values in the PAF-20 correspond more to changes in the NP.
目的
通过磁共振成像（MRI）T2 映射来显示后纤维环（AF）中的腰椎间盘突出症。
方法
在 3.0 特斯拉（3T）条件下获取 64 例腰痛患者的 313 个腰椎间盘的矢状位 T2 映射图像。根据椎间盘突出和膨出情况对椎间盘进行评级。在矢状位 T2 映射图像上进行感兴趣区域（ROI）分析。比较椎间盘后 10%（PAF - 10）和后 20%（PAF - 20）的 AF 的 T2 值。
结果
与膨出椎间盘和侧方突出椎间盘相比，影响成像区域的突出椎间盘在 PAF - 10 中的 T2 值显著增加，且与髓核无明显关联。PAF - 20 与髓核（NP）呈中度相关。
结论
PAF - 10 中高 T2 值提示存在椎间盘突出（DH）。结果表明，PAF - 20 中的 T2 值更对应于 NP 的变化。
