Abstract
This review focuses on the ex vivo magnetic resonance imaging (MRI) modeling of medial temporal cortices and associated structures, the entorhinal verrucae and the perforant pathway. Typical in vivo MRI has limited resolution due to constraints on scan times and does not show laminae in the medial temporal lobe. Recent studies using ex vivo MRI have demonstrated lamina in the entorhinal, perirhinal, and hippocampal cortices. These studies have enabled probabilistic brain mapping that is based on the ex vivo MRI contrast, validated to histology, and subsequently mapped onto an in vivo spherically warped surface model. Probabilistic maps are applicable to other in vivo studies.
摘要
这篇综述专注于内侧颞叶皮质及其相关结构、内嗅疣和穿通纤维束的离体磁共振成像（MRI）建模。典型的活体 MRI 由于扫描时间的限制，分辨率有限，并且无法显示内侧颞叶的层。最近使用离体 MRI 的研究已经证明了内嗅皮质、边缘皮质和海马皮质中的层。这些研究使基于离体 MRI 对比的概率脑映射成为可能，该对比已通过组织学验证，随后映射到活体球型扭曲表面模型上。概率图适用于其他活体研究。
