中间段(绿色线)与环池相关,而后段与四叠体池(红色线)相关。颞叶内侧的前段由颈动脉、MCA、AChA和PCA供血。颞叶内侧的中间和后段主要由PCA提供。B,颞叶的基底面。左侧海马旁回和海马已被切除,以更好地暴露它们的脑池和血管关系。T1加权轴向MRI(插图)显示MTR节段与解剖解剖相关。
本研究通过结合 T1 加权和 T2 加权MRI,首次在体内研究癫痫患者髓鞘相关的微观结构特征,提供了一种新的工作流程。mSCN 的失连接表明 TLE 是一种在脑区和网络层面上存在广泛失连接的系统紊乱疾病。 Keywords:hippocampus, magnetic re...

【背景】内侧颞叶(medial temporal lobe, MTL)与情景记忆密切相关,它易受阿尔茨海默病(Alzheimer’s disease, AD)病理的影响。MTL由海马和海马旁回附近的亚结构组成。海马旁回和海马都可以分为前部和后部,其中,海马旁回前部包括嗅周和内嗅皮层,后部包括海马旁皮层。MTL自身内部以及其与皮层和皮层下脑区紧密相连...
Diencephalon including the thalamus, the pulvinar nuclei, the habenula, the pineal gland, the infundibulum (formerly the pituitary stalk) and the neurohypophysis (the anterior lobe of the pituitary gland not forming part of the central nervous system). Figure 8 - Anatomy of the brain (MRI) Ce...
MR spectroscopy may be useful even when the routine MRI is normal. Proton MR spectroscopy of the brain is abnormal in neonates exposed to HIV in utero, although this does not differentiate infected children from uninfected children. A non-specific amino acid peak in the 2.1–2.6 ppm area ...

They will most likely use an MRI, which is the best imaging test to identify a brain tumor, but they may use a CT scan if you can't have an MRI for some reason. You will likely need to be injected with a contrast agent before your test. This makes the tumor easier to see. ...
The detailed anatomical information of the brain provided by 3D magnetic resonance imaging (MRI) enables various neuroscience research. However, due to the long scan time for 3D MR images, 2D images are mainly obtained in clinical environments. The purpo
