Reliable measurement of different tissue volumes in the living brain is of great importance for human brain research. In this article, we report on the inter- and intraoperator reliability and scan-rescan reproducibility of segmented intracranial tissue volumes from MR images using the image analysis software suite BRAINS. The absolute data of tissue volume measurements are also presented. The reliability and consistency of the measurements of the segmented volumes were excellent. The segmentation is robust and rapid and the volume measurements are plausible and suitable for quantitative studies in clinical brain research.
在活体大脑中对不同组织体积进行可靠测量对于人类大脑研究极为重要。在本文中,我们报告了使用图像分析软件套件BRAINS从磁共振成像(MR)图像中分割出的颅内组织体积在不同操作人员之间以及同一操作人员内部的可靠性,以及扫描 - 再扫描的可重复性。同时还给出了组织体积测量的绝对数据。分割体积测量的可靠性和一致性非常出色。这种分割方法稳健且快速,体积测量合理,适用于临床脑研究中的定量研究。
