摘要: 目的:探讨大脑颞上沟在MRI横断面及矢状面图像上的形态学规律。方法:在eFilm2.1工作站中,将获取的29名正常成人志愿者头颅连续MRI扫描数据,采用连续追踪法和3D-CuRsoR技术,对连续MRI横断面及矢状面图像上的颞上沟进行识别、观测,统计其形态学特征。结果:颞上沟可出现在Z=-36～48 mm区段的MRI横断层图像上(95%分布于Z=-30～42 mm层面上),并随着层面的上移而沟后移;矢状面上颞上沟分为前部的水平段及后部的升段;在Z=-6～6 mm层面上颞上沟出现明显向后上走行的与颞上沟前部呈较大钝角的拐点,在Z=-21～12 mm的横断面上颞上沟可出现多沟表现(95%分布于Z=-18～9 mm层面上)。结论:本文结果可帮助颞上沟的快速识别和颞上沟周围重要结构的准确定位。Abstract: Objective:To explore the morphology rule of cerebral superior temporal sulucs(STS) on the MRI cross section and the sagittal plane image of brain.Methods:In the eFilm2.1 workstation,29 normal adult volunteer head continuously MRI scanning data which will gain,uses the continuous tracking method and the 3D-Cursor technology,STS carries on the recognition,the observation to continuously on the MRI cross section and the sagittal plane image,to count its morphological character.Results:The STS may appear in Z =-36-48 mm on the sector MRI cross fault image(95% distributes in the Z =-30-42 mm stratification plane),and after the stratification plane uppers shift the sulci move backward.STS can be divided into anterior horizontal part and posterior ascending part in the sagittal plane.In the Z =-6-6 mm stratification plane STS can assume the big obtuse angle backward obviously the inflection point; STS may present the multi-ditch performance in the Z =-21-12 mm cross section(95% to distribute in the Z =-18-9 mm stratification plane).Conclusions:This article result may help STS fast recognition and around the ditch the important structure accurate localization.
