We investigated the anatomical location of the spinothalamic tract and its thalamocortical pathway (STT) in the subcortical white matter in normal subjects, using diffusion tensor tractography (DTT).
The STT was reconstructed using FMRIB software in 40 normal subjects. The most probable locations of the STT were defined as the location on an axial slice of the centrum semiovale (CS), corona radiata (CR), and posterior limb of the internal capsule (PL).
The STT was located at an average of 62.66% in the anterior to posterior direction along a horizontal line that passed between the anterior and posterior ends of the brain, and an average of 36.29% lateral from the midline in the CS. In the CR, the STT was located at an average of 79.60% in the anterior to posterior direction along the aforementioned horizontal line, and an average of 36.36% lateral from the midline. In the PL, the STT was located at an average of 83.58% in the anterior to posterior direction along a horizontal line that passed the middle point at the genu of the internal capsule and the posterior endpoint of the putamen, and an average of 69.69% lateral from the midline to the lateral end of the putamen.
We found the precise anatomical location of the STT in the subcortical white matter in the human brain using DTT. We believe that the results of this study will be helpful to clinicians in the neuroscience field.
我们使用弥散张量纤维束成像（DTT）研究了正常受试者皮质下白质中脊髓丘脑束及其丘脑皮质束（STT）的解剖位置。
在 40 名正常受试者中，使用 FMRIB 软件重建了 STT。STT 的最可能位置定义为半卵圆中心（CS）、放射冠（CR）和内囊后肢（PL）轴位切片上的位置。
STT 在前-后方向上位于穿过大脑前-后两端的水平线的平均 62.66%处，在 CS 中平均距离中线 36.29%。在 CR 中，STT 在前-后方向上位于穿过上述水平线的平均 79.60%处，平均距离中线 36.36%。在 PL 中，STT 在前-后方向上位于穿过内囊膝部中点和豆状核后端的水平线的平均 83.58%处，平均距离中线到豆状核外侧 69.69%。
我们使用 DTT 发现了人类大脑皮质下白质中 STT 的精确解剖位置。我们相信这项研究的结果将有助于神经科学领域的临床医生。
