扩散张量成像（DTI）在过去十年中有了很大的发展，现在正在敲开更广泛的临床应用的大门。在过去的十年中，已经有一些努力，以寻求有价值的和可靠的应用DTI在不同的神经系统疾病。DTI在预测脑肿瘤患者预后中的作用已被广泛研究，并已成为这方面相当成熟的临床工具。最近，DTI已被应用于轻度创伤性脑损伤，以预测基于白色物质束的DTI的临床结果。近年来，随着磁强度的增加和纤维束成像后处理的改善，基于DTI的白色纤维束成像的分辨率有所提高。DTI在出血性卒中中的作用已在科学文献中进行了初步研究。有证据表明，在颅内出血的动物模型中，DTI可以有效地预测运动功能的结果。在蛛网膜下腔出血或脑室内出血的情况下，仅进行了少数DTI研究。在这篇文章中，我们将回顾DTI的演变，现有的证据表明其在出血性中风中的作用，并讨论这种非侵入性评估技术的人类大脑白色物质束在未来的可能应用。
Diffusion Tensor Imaging (DTI) has evolved considerably over the last decade to now be knocking on the doors of wider clinical applications. There have been several efforts over the last decade to seek valuable and reliable application of DTI in different neurological disorders. The role of DTI in predicting outcomes in patients with brain tumors has been extensively studied and has become a fairly established clinical tool in this scenario. More recently DTI has been applied in mild traumatic brain injury to predict clinical outcomes based on DTI of the white matter tracts. The resolution of white matter fiber tractography based on DTI has improved over the years with increased magnet strength and better tractography post processing. The role of DTI in hemorrhagic stroke has been studied preliminarily in the scientific literature. There is some evidence that DTI may be efficacious in predicting outcomes of motor function in animal models of intracranial hemorrhage. Only a handful of studies of DTI have been performed in subarachnoid hemorrhage or intraventricular hemorrhage scenarios. In this manuscript we will review the evolution of DTI, the existing evidence for its role in hemorrhagic stroke and discuss possible application of this non-invasive evaluation technique of human cerebral white matter tracts in the future.
