Over the last several years, specific radiological techniques have been used for the analysis of the central nervous system pathways. They involve a magnetic resonance sequence called diffusion tensor imaging. In order to process the data provided by this sequence it is necessary to use software that can post-process the image and render three-dimensional images of the central nervous system pathways. Thanks to this sequence it has been possible to isolate over the years many nerve pathways that cross the brain tissue, particularly those which occupy a significant space. This sequence could have a large variety of uses, such as helping with the study of brain anatomy, assisting with surgery planning, or establishing a relationship between the nerve fibers and tumoral lesions. However, there has been an increasing number of cases that report a low reliability related to the tractographic representation of this technique. Our goal with this article is to analyse a specific nerve pathway, the piramidal tract, in order to assess the coherence between the images obtained and the anatomy that is already known from the perspective of the radiological image, and to compare this tract between different patients.
在过去的几年中，已经使用了特定的放射学技术来分析中枢神经系统通路。它们涉及一种称为弥散张量成像的磁共振序列。为了处理该序列提供的数据，有必要使用能够对图像进行后处理并呈现中枢神经系统通路三维图像的软件。由于这个序列，多年来已经可以分离出穿过脑组织的许多神经通路，特别是那些占据很大空间的神经通路。这个序列可以有很多用途，例如帮助研究大脑解剖结构、协助手术规划，或者建立神经纤维与肿瘤病变之间的关系。然而，越来越多的病例报告称该技术的轨迹表示存在可靠性问题。我们这篇文章的目的是分析特定的神经通路，即锥体束，以评估所获得的图像与从放射学图像角度已经知道的解剖结构之间的一致性，并在不同患者之间比较这个通路。
