The morphology and stereotaxy of bifurcation of the cerebral collateral sulcus

Objective:To explore the morphology of cerebral collateral sulcus(COS) on the MRI cross section and coronal plane image of brain.Methods:In the eFilm2.1 workstation, the continuously cross section and coronal plane MRI scanning data of 40 health adult volunteer brain were selected.The morphological characteristics of COS on the continuously cross section and coronal plane MRI were identified, observed and analyzed using the structure continuous tracking method and 3D-Cursor technology.Results:The collateral sulcus could be divided into the sulcus olfactorius nasi, middle collateral sulcus and occipital collateral sulcus.With the stratification plane rearward shift, the collateral sulcus on the coronal plane image moved upper.The 72.5% of occipital collateral sulcus was divided into the medial and lateral branches.The mapping length of collateral sulcus on the coronal plane and cross section plane equaled to the number of plies of cross section times 2 mm and number of plies of coronal plane times 2 mm, respectively.Conclusions:The morphological pattern of COS in the MRI cross and coronal-sectional images can provide the anatomical information for identifying and locating the collateral sulcus and its adjacent brain lesion.
