磁共振影像对判定中央沟的价值

Identification of the Central Sulcus in Magnetic Resonance Imaging

目的 通过使用磁共振影像技术来研究中央沟及其相邻解剖结构在影像中的特征性表现。方法 任选10 0例常规头部磁共振检查的患者 ,进行常规磁共振扫描 ,并将患有脑内疾患的 3 1例患者的磁共振影像与临床表现进行比较。结果 明确判定中央沟位置 98例 ,中央前回的厚度大于中央后回的 93例 ,中央前回与中央后回厚度之比左侧半球 :1 73 6,右侧半球 :1 65 2 ;额上沟与中央前沟相交的 80例 ,3 1例患有脑内疾病的磁共振影像病变的位置与临床神经定位是相一致的。结论 磁共振影像是判定中央前回 (运动中枢 )、中央后回 (感觉中枢 )、中央沟及额上沟最为有效的影像学方法。

Purpose Significance to study of the central sulcus,precentral and postcentral gyri by MR imaging,to determine its location for application of the clinic. Methods In 100 patients,choice routine examined axial SE T 1WI and FSE T 2WI MR findings.We compare MR imaging representing and clinical symptom in 31 with brain lesion's patients. Results In all subjects,identification central sulcus in 98 cases.Precentral gyri thickness more big postcentral gyri in 93 cases.The mean ratio of percentral/postcentral gyri was 1 736 for left hemisphere and 1 652 for right hemisphere.The superior frontal sulci with precentral sulci intersect in 80 cases.At 31 with brain lesion's patients,MR findings with clinical symptom had same location in the brain gyri. Conclusion MR imaging is best method to determine the precentral gyri,postcentral gyri,central sulci and superior frontal sulci. [
