随着医学影像学技术的迅速发展,扩散张量成像(DTI)对轻度创伤性脑损伤(mild traumatic brain injury,m TBI)的诊断和预后评估已经成为研究热点,DTI能无创性在体研究脑白质显微结构的改变,有利于了解白质束结构和功能间的联系。1研究现状创伤性脑损伤(traumatic brain injury,TBI)是指由于外力所致的脑部损伤,是临床上常见的神经外科疾病。TBI按其临床表现,又可分为轻、中、重三型。其中以m TBI最常见[1]。随着社会的发展,生活水平的提高,TBI发病率呈持续性增
With the rapid development of medical imaging technology, the diagnostic and prognostic evaluation of diffusion tensor imaging (DTI) for mild traumatic brain injury (m TBI) has become a research hotspot. DTI can be used as a noninvasive in vivo study Changes in the white matter microstructure helps to understand the relationship between white matter structure and function. 1 research status Traumatic brain injury (traumatic brain injury, TBI) refers to the external force due to brain damage, is a common clinical neurological disease. TBI according to their clinical manifestations, but also can be divided into light, medium and heavy three types. Which m TBI most common [1]. With the development of society and improvement of living standard, the incidence of TBI has been continuously increased
