摘要

目的

高分辨磁共振结构成像可以揭示大脑皮层的结构特征

并可以解释正常脑发育及神经心理性疾病。本研究旨在采用基于表面的形态测量学方法比较正常受试者在3T与7T磁共振高分辨结构成像的差异。

方法

12个健康志愿者分别在3T磁共振上行三维快速T1加权快速毁损梯度回波成像及在7T磁共振上行三维T1加权磁化准备快速梯度回波序列。采用FreeSurfer软件处理数据。计算皮层厚度、白质及灰质表面积、凸率、曲率

并采用配对

检验进行比较。

结果

3T磁共振上受试者平均皮层厚度、白质总面积、灰质总面积要大于7T （左侧大脑半球P值分别是0.000

0.006及0.020;右侧大脑半球P值分别为0.000

0.000

0.000）。与3T磁共振成像比较

全脑基于表面的形态测量学证实

皮层厚度、白质表面、灰质表面、凸率、曲率在7T磁共振成象上存在减少或增加的情况。

结论

本研究结果证实3T与7T磁共振成像设备存在脑结构属性特征的不一致性。当采用超高场MR系统探索脑结构变化时

研究者对数据的解释应当保持谨慎态度。

Abstract

Objective

High resolution structural MR imaging can reveal structural characteristics of cerebral cortex and provide an insight into normal brain development and neuropsychological diseases. The aim of this study was to compare cortical structural characteristics of normal human brain between 3T and 7T MRI systems using surface-based morphometry based on high resolution structural MR imaging.

Methods

Twelve healthy volunteers were scanned by both 3T with 3D T1-weighted fast spoiled gradient recalled echo (3D T1-FSPGR) sequence and 7T with 3D T1-weighted magnetization-prepared rapid gradient echo (3D T1-MPRAGE) sequence. MRI data were processed with FreeSurfer. The cortical thickness

white and gray matter surface area

convexity

and curvature from data of 3T and 7T were measured and compared by paired

-test.

Results

Measurements of mean cortical thickness

total white matter surface area and gray matter surface area of 3T were larger than those of 7T (left hemisphere:

=0.000

0.006

0.020 respectively; right hemisphere:

=0.000

0.000

0.000 respectively). Surface-based morphometry over the whole brain demonstrated both reduced and increased measurements of cortical thickness

white and gray surface area

convexity

and curvature at 7T compared to 3T.

Conclusions

Inconsistency of brain structural attribute between 3T and 7T was confirmed

and researchers should be cautious about data when using ultrahigh field MR system to investigate brain structural changes.
