Sulcus Temporalis Inferior:Computational Sectional Imaging Anatomy And Three-Dimensional Visualization

Background:Thanks to the development of modern science and technology,great changes have taken place in clinical diagnosis and treatment work,diagnosis of diseases related to the body feeling and body movement and minimally invasive neurosurgery and functional neurosurgery based on advanced and new technology has gradually transformed from the traditional large trauma craniotomy surgery to minimally invasive treatment,the brain circuitry anatomy is the basis of surgical lesions accurate positioning.Nowadays,the exploration of the brain has also developed from its superficial spatial anatomy to the deep direction of three-dimensional spatial orientation,functional learning and internal interconnection of various organizational structures.Sulcus temporalis inferior(STI)is a relatively fixed form in the structure of human brain.During the development of brain tissue,the superior temporal sulcus is classified into the primary structure.The superior temporal sulcus is composed of the upper and inferior temporal gyrus and the inferior temporal gyrus.The study of Zhenping Li showed that the sulcus temporalis inferior is almost parallel to the superior temporal sulcus,and the end of the line goes backward and extends into the posterior portion of the superior temporal gyri,which is connected to the anterior caking of the occipital.The study of spatial anatomy and histology of sulcus temporalis inferior can greatly help to understand the related anatomical and biological functions of adjacent tissues.Nowadays,there is a lack of detailed research on the spatial structure of the Sulcus temporalis inferior.Therefore,25 adult cases whose relevant examination and inspection had no apparent organic and functional lesion of their head MR images were selected into this research,measure the coordinate of sulcus temporalis inferior in the threedimensional coordinates,and obtain its regression equation.The three-dimensional space model is modeled according to the spatial coordinate data set of the sulcus temporalis inferior to provide three-dimensional space anatomical information of sulcus temporalis inferior for neuroimaging,minimally invasive neurosurgery and other clinicians.Objective: To explore the anatomical features of sulcus temporalis inferior in transverse and sagittal plane by studying the adult cephalic MR image.To construct a spatial three-dimensional coordinate set in three-dimensional space coordinate system of the superior temporal sulcus.To construct a regression equation in the three-dimensional space coordinate system.To construct a three-dimensional model of the sulcus temporalis inferior,and to provide accurate visualization of three-dimensional anatomy in the brain neuroimaging and minimally invasive neurosurgery.Methods: Select craniocerebral MR images of 25 adult cases into the group,the anterior and posterior interconnection AC-PC line was used as the scanning baseline,the horizontal thickness of the transverse plane was 3mm,and the thickness of the sagittal plane was 7mm.Import brain MR image scanning data to Dicom3.0 format guide to eFilm 2.1 software.With the aid of software "tracking and 3d-Cursor" function in cerebral transverse,we scan images under the sulcus temporalis inferior accurate spatial anatomical morphology data information.Record coordinates of each point of sulcus temporalis inferior,construct the three-dimensional space coordinates.Data of brain MR of the 25 cases was imported into Adobe Photoshop CC14.0,we calculate the space coordinates set on each section of the regression equation.Split the brain surface,lateral ventricle and the sulcus temporalis inferior,then carry on the three-dimensional reconstruction.Results: Sulcus temporalis inferior was accurately identified in the transverse surface of the brain,and the anatomical morphology and spatial coordinates of the inferior temporal sulcus were accurately measured.Morphological features of sulcus temporalis inferior can be described,the regression equations of the coronal and sagittal plane of sulcus temporalis inferior was successfully calculated.A three-dimensional space reconstruction was performed in the sulcus temporalis inferior,and a more detailed description was made of the spatial anatomy of the inferior temporal sulcus and the surrounding area.Conclusion: Sulcus temporalis inferior can be accurately identified in the cerebral MR,which can provide minimally invasive neurosurgery for clinical work and related functional neurosurgery operation and subject of area scanning image positioning with coordinate data based on sulcus temporalis inferior.The spatial three-dimensional coordinates were measured in this study described anatomical morphology of brain circuitry organization and it provided more objective digital basis.Three-dimensional model can intuitively show the sulcus temporalis inferior and lateral ventricle in three-dimensional anatomical position of the entire brain,which makes an important impact on clinical diagnosis and treatment and scientific research teaching.
