摘　　要：豆纹动脉是颅内的重要穿支动脉,分布于基底节区及深部核团,其病变会导致相应供血区域微循环障碍,是发生脑卒中的重要危险因素。早期有效检出豆纹动脉病变明确脑卒中的分类及病因,并对不良事件进行有效的预测,成为一个亟待解决的问题。由于豆纹动脉极其纤细、走行迂曲,目前临床常规使用的影像设备及技术在清晰度、全面显示上受到明显限制。随着MRI技术的不断发展,7.0T超高场强MRI目前已成为无创性诊断颅内豆纹动脉的最佳方法。本研究总结应用7.0T超高场强MRI探讨豆纹动脉及脑卒中相关疾病关系的研究进展。The lenticulostriate arterys(LSAs)is an important intracranial perforating artery,which is located in the basal ganglia region and the deep nucleus.LSAs lesions will lead to microcirculation disorders in the corresponding blood supply area,which is an important risk factor for stroke.Early effective detection of LSAs lesions to clarify the classification and etiology of stroke,and effective prediction of adverse events has become an urgent problem to be solved.At present,due to the extremely slender diameter and tortuous course of LSAs,the equipment and technology in clinical have not achieved a clear and comprehensive display of the LSAs.With the development of 7.0T ultra-high field MRI,it has become the best method for non-invasive diagnosis of LSAs.This paper aims to summarize the research progress of LSAs and stroke related diseases by 7.0T ultra-high field MRI.
