3T MRI investigation for traffic accident mechanism

我们已经报道了脑白质疏松症(LA)，这是一种常见的脑部MRI发现，与十字路口撞车显著相关。在这项研究中，我们使用基于区域的空间技术来分析分数各向异性(FA)值。随后，我们集中测量了前额叶皮质下的额枕束的平均FA值。受试者被分成三组，第一组是5名没有LA的男性，第二组是5名LA男性，有十字路口撞车史，驾驶能力很好，第三组5名LA男性，没有十字路口撞车史，驾驶能力很差。采用CRT驾驶试验和DS试验评价驾驶能力。平均FA值按群的顺序显著降低。结果表明，LA引起的交叉路口车祸的可能原因可能与FA值评估的神经网络损害的扩大有关

We have reported that leukoaraiosis (LA), a common finding in brain MRI, significant ly associated with cross road crashes. In this study, we analyzed the fractional anisotropy (FA) values by using a tract-based spatial technique. We subsequently focused on measuring the mean FA value of the fronto-occipital fasciculus in the subcortex of the prefrontal. Subjects were divided in three groups, the first group was five men without LA, the second five men with LA and with a history of cross-road crashes and a good driving ability, the third five men with LA but no history of cross-road crashes and a bad driving ability. Driving ability was evaluated with CRT driving test and DS test. The mean FA value significantly decreased according to the roup order. The results showed the possible cause of cross-road crashes due to LA may be involved in the extension of neuronal network damages evaluated by FA values
