翼 (RW) 是潜在的手术目标,位于牙--管 (DRT) 内. 虽然它的重心准确,但精确的体积定位需要先进的成像,因为信号噪声比较低.
科学领域:
- 神经外科 神经外科
- 神经成像是一种神经成像.
- 曲谱学 曲谱学 曲谱学 曲谱学
背景情况:
- 对的立体外科手术从先进的成像技术中受益.
- 白物质减弱序列揭示了亚thalamic区域的低压,称为rubral翼 (RW).
- 脊髓与牙 - 脊髓 - 胸膜管道 (DRT) 的关系需要进一步的定义,以便在手术中应用.
研究的目的:
- 为了研究翅膀 (RW) 作为的外科目标.
- 在体积上和通过曲谱学来描述RW.
- 为了确定RW与牙 - 面膜 - 胸膜通道 (DRT) 的解剖关系.
主要方法:
- 从77名受试者的FLAWS序列上手动划分RW.
- 使用人类结合体项目的数据集 (n=1000) 对DRT的曲谱分析.
- 对交叉 (DRTx) 和未交叉 (DRTu) DRT部分的纤维紧密度峰值的识别.
主要成果:
- 在所有受试者中都可以识别RW,用于体积比较的DICE系数低 (0.54).
- RW的重心 (COG) 始终位于2mm以内.
- RW划分了DRT (DRTx) 的交叉后部分,将纤维引导到前中心 (PCG).
结论:
- 翼 (RW) 是震手术的可行目标,代表DRTx.x的部分.
- 准确确定RW的COG是可行的,但由于SNR低,精确的体积评估是具有挑战性的.
- 额外的成像可能是必要的,以获得最佳的手术准RW.

Functional Brain Systems: Reticular Formation
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...
