摘要

使用类内相关系数、相关分析和Bland-Altman分析对40名健康志愿者通过0.3- t和3-T扫描仪获得的颅内组织体积进行比较。我们发现在所有组织和大部分大脑区域中存在较高的类内相关系数、较高的Pearson相关系数和较低的百分比偏差，尽管在某些区域观察到微小的差异。这些发现可能支持低场磁共振成像脑容量测量的有效性。

Comparison of Brain Volume Measurements Made with 0.3- and 3-T MR Imaging.

The volumes of intracranial tissues of 40 healthy volunteers acquired from 0.3- and 3-T scanners were compared using intraclass correlation coefficients, correlation analyses, and Bland-Altman analyses. We found high intraclass correlation coefficients, high Pearson's correlation coefficients, and low percentage biases in all tissues and most of the brain regions, although small differences were observed in some areas. These findings may support the validity of brain volumetry with low-field magnetic resonance imaging.
