弥散成像(DWI)技术是近几年来发展起来的新技术,通过组织水分子的细微弥散变化情况来反映组织的病理生理过程,为癫痫研究提供了一种全新的研究方法。DWI可以反映癫痫发作过程中的病理生理变化过程以及海马硬化的病理改变并对其进行定位,同时DWI亦有助于癫痫致痫灶的准确定位,对癫痫的手术治疗有重要价值。 Diffuse imaging (DWI) is a new technique developed in recent years. It can reflect the pathophysiological process of tissue through the subtle dispersion of water molecules, providing a new research method for epilepsy research. DWI can reflect the pathophysiological process of epileptic seizures and the pathological changes of hippocampal sclerosis and locate them, meanwhile, DWI can also help the accurate localization of epileptic foci of epilepsy, which is of great value to the surgical treatment of epilepsy.
