Purpose: Our study aimed to determine the possible differences in linear measurements and linear indices values of intracranial fluid spaces (IFS) between right- and left-handed adults.

Methods: This work has been carried out on 148 subjects (72 men and 76 women). In the study, 88 right-handers and 60 left-handers were included. Forty of the right-handers were male, 48 were female, and 32 of the left-handers were male, and 28 were female. The ages were between 20 and 50 years. Linear measurements were obtained based on magnetic resonance imaging (MRI) studies. A 1.5-T MRI scanner was used to obtain axial images. The ten parameters were estimated from MRI scans.

Results: There was no correlation between parameters and age. In our study, interestingly, as can be seen from the tables, most of the parameters with statistically significant differences were higher in favour of left-handed subjects. In most of the linear measurement results, IFS values of the right hemisphere in right-handers, and the left hemisphere in left-handers were higher. Similar results were found in favour of the left-handed in most of the linear ventricular indices.

Conclusion: Linear measurements and linear indices values of IFS were mostly higher in left-handers than in right-handed individuals.

目的：我们的研究旨在确定右手和左手成年人之间颅内液空间 (IFS) 的线性测量值和线性指数值的可能差异。

方法：这项工作已对 148 名受试者（72 名男性和 76 名女性）进行。在这项研究中，包括 88 名右撇子和 60 名左撇子。右撇子中男性40人，女性48人，左撇子男性32人，女性28人。年龄在20到50岁之间。线性测量是基于磁共振成像 (MRI) 研究获得的。1.5-T MRI 扫描仪用于获得轴向图像。这十个参数是从 MRI 扫描中估计出来的。

结果：参数与年龄之间没有相关性。在我们的研究中，有趣的是，从表中可以看出，大多数具有统计显着差异的参数都较高，有利于左撇子受试者。在大多数线性测量结果中，右撇子的右半球和左撇子的左半球的 IFS 值较高。在大多数线性心室指数中发现类似的结果有利于左手。

结论：左撇子的 IFS 线性测量值和线性指数值大多高于右撇子。
