摘要
目的:为海马的影像学检查诊断及手术治疗提供解剖学依据。方法:采用薄层冰冻铣切技术取成年男性颅脑标本平行于眦耳线的横切面图像,与相应活体层厚5 mm的1.5T磁共振图像进行对比观察。结果:海马在视交叉下方平面开始出现,视束及前连合平面最为典型,室间孔平面变小并逐步消失,大约占据4 cm的厚度。结论:1.5T磁共振T1加权像能较好显示海马及相关结构,侧脑室及其内部结构是确定海马位置及分部的最佳标志。
Objective： To provide anatomic data for diagnostic imaging and operative treatment of hippocampus. Methods： The mill-like method was adopted to obtain thin sections of a head specimen from a adult Chinese male corpse and take digital photographs, with the section line parallelling the canthomeatal line. And then, image data were observed and compared with MRI images with the thickness of 5 mm. Results： The hippocampus appeared below optic chiasma plane, and showed clearly on optic tract and anterior commissure plane, and gradually disappeared on interventricular foramen plane. Its thickness was about 4 cm. Conclusions： Hippocampus and its related structures can be distinguished in T1 weighted image of 1.5T MRI. Lateral ventricle and its internal structures is the best marks to locate hippocampus.
