1.200 cerebral hemispheres were used to observe the morphology of the brain sulci. 2.The superior and inferior frontal sulci not only run from tbe precentral sulcus or in the front of it,but also run behind it. 3.The posterior end of the collateral sulcus may extend to the superolateral sur- face of the occipital lobe. 4.The orbital sulci are irregular but generally are of the Ж-shaped and H- shaped. 5.Anterio-superiorly to the cingulate sulcus a parallel accessory cingulate sulcus is usually present. 6.The intraparietal and intraoccipital sulci are usually continuous. 7.The superior and inferior transverse occipital sulci are present at the same time,being over 80% of the total number. 8.The parieto-occipital sulcus which commences on the superolateral surface is over 90% of the total number. 9.The calcarine sulcus is divided into four types,among which the“superior convex”and “linear”types are present more often. 10.Most of the superior sagittal cunuate sulcus and the inferior sagittal cunuate sulcus are present. 11.The lingual sulcus is constant.Its configuration is changed,following the change of the posterior part of the calcarine fissure and the posterior end of the collateral sulcus.

1.额上沟和额下沟不仅可以起自中央前沟及其前方,也可以起自它的后方。2.侧副裂的前后两端变化很大,后端有时可伸至枕叶的背外侧面。3.眶沟的变化虽然很大,但它的基本型为Ж型和 H 型。4.扣带沟的前上方常见平行的副扣带沟。5.顶间沟与枕间沟在形态上常是连续的,顶间沟多数末端连枕横沟,枕间沟有13%可达枕极。6.上枕横沟与下枕横沟同时存在者占85%上,上枕横沟可以单独存在,但未见下枕横沟单独存在。7.顶枕裂约有90%进入背外侧面,末端分叉是由于沟底的顶枕裂盖部的上部露出表面所致。8.距状裂后段可分为四型,其中以“上凸型”和“直线型”最为多见。9.楔上矢状沟和楔下矢状沟多数存在。10.舌沟较恒定,其形态随距状裂后段和侧副裂后端的变化而改变。

Materal and Methods: 50 cases (100 hemipheres) of normal brain with edal son of SE T1WI and T2WI were chosen on Resonex 0. 38T MRI system. Anatomical features of cerebral suet were recorded and observed with double blind method by two doctors. Result: The demonstration rates of SFS、PreCS、CS、PM、PostCS、and IPS were 100%、97%、100%、94%、96%、ac 98% on MRI,respectively. The applicability of SFS-PreCS sign. Pars bracket sign、 Hook sign、Thin postCY sign, IPS postCS signs were 0. 87、0. 90、0. 98、0. 98、and 0. 92; The clinical applicability of CS sign、Bifid postCS sign、PM deflection sign and Digital white matter patter were 0. 70、0. 74、0. 68、0. 69, respectively, the accuracy rate of the latter two reached 100%, but the demonstration rate appeared low. Conclusion: No single sign was 100% of effective. Combination of some signs proved to be the most reliable and effective for localizing sulci、gyri and pathology.

探讨定位中央沟和邻近脑回的各种MRI证象及其显示率和临床应用价值。材料和方法:收集50例(100个半球)的正常人群,均经SE序列横断面MRI扫描T1、T2加权成像,两位医生双盲法阅片并记录脑沟回的解剖特点。结果:额上沟、中央前沟、中央沟、边缘支、中央后沟及顶内沟在MRI上的显示率分别为100%、97%、10o%、94%、96%、和98%;额上沟-中央前沟征、边缘支括弧征、钩形征、薄中央后回征及顶内沟-中央后沟征的临床应用价值分别为0.87、0.90、0.98、0.98和0.92而中央沟征、分叉中央后沟征、边缘支偏斜征、脑白质指样征的应用价值仅为0.70、0.74、0.68和0.69;后二者的准确度为100%;但显示率低。结论:单一征象都不是100%的有效;多征象的结合有助于脑沟回及病变区的准确定位。
