OBJECTIVE
The purpose of our study was to determine the main anatomical features of the calcarine sulcus using a 3-T MRI.
METHODS
Fifty human brains have been explored using an MRI 3-T in Doctors Center in Beirut (Lebanon).
RESULTS
The calcarine sulcus was identified in 100% of cases. In most cases, it had a continuous aspect with several peaks. In all our specimens, the calcarine sulcus crosses the parieto-occipital fissure. The majority of their collateral branches and their connections with other sulci were located at the level of the calcarine sulcus properly. In the majority of specimens, the deepest part of the anterior calcarine sulcus forms a protrusion in the occipital horn of the lateral ventricle called calcar avis.
CONCLUSION
Our study emphasizes the fact that the course patterns of the calcarine sulcus are highly variable. The description of the main anatomical features of the calcarine sulcus obtained from our study can be used as a reference for fMRI exploration and is useful for brain surgery.
目的
我们研究的目的是使用3-T磁共振成像（MRI）确定距状沟的主要解剖特征。
方法
在黎巴嫩贝鲁特的医生中心，使用3-T MRI对50个大脑进行了研究。
结果
在所有病例中均识别出距状沟。在大多数情况下，它呈连续状且有多个峰。在我们所有的标本中，距状沟穿过顶枕裂。其大多数侧支及其与其他脑沟的连接恰位于距状沟水平。在大多数标本中，距状沟前部最深的部分在侧脑室枕角形成一个突起，称为禽距。
结论
我们的研究强调了距状沟走行模式高度可变这一事实。从我们的研究中获得的距状沟主要解剖特征的描述可作为功能磁共振成像（fMRI）探索的参考，并且对脑外科手术有用。
