【摘要】 高角度分辨力扩散成像（HARDI）是一种高b值、多扩散梯度方向的扩散成像，不仅能够有效解决神经纤维交叉及部分容积效应的问题，而且能准确地观察颅内白质纤维束的形态及特征。了解扩散加权成像、扩散张量成像的原理，继而掌握HARDI技术的原理、优点及在神经科学研究领域的应用，对于HARDI技术的临床推广及应用具有重要意义。更多还原

【Abstract】 High Angular Resolution Diffusion Imaging(HARDI) is a diffusion imaging technique with a high b-value and multiple diffusion gradient directions. It not only effectively addresses the issues of neural fiber crossing and partial volume effects but also accurately observes the morphology and characteristics of white matter fiber bundles in the intracranial space. Understanding the principles of diffusion-weighted imaging and diffusion tensor imaging, and then mastering the principles and advantages of HARDI technology, as well as its applications in the field of neuroscience, is of significant importance for the clinical promotion and application of HARDI technology.更多还原
