摘　　要：颅内动脉瘤(IA)发病率、致残率及死亡率均较高。血流动力学是评估动脉瘤破裂风险和预测预后的重要依据。四维血流MRI(4D flow MRI)是新型相位对比MRI技术,可较传统二维相位对比MRI(2D PC MRI)和多普勒超声更为全面直观地展示病变的血流模式、更准确地定量评价血流动力学参数,目前已用于分析颅内、心脏等的血流动力学。本文就4D flow MRI技术用于IA进展进行综述。Intracranial aneurysm(IA)is a disease with high incidence rate,also high disability and high mortality rate.Hemodynamic parameters play an important role for evaluating the rupture risk and prognosis of aneurysms.Four-dimensional flow MRI(4D flow MRI)is a new phase contrast MRI technique,which can display the lesions’blood flow patterns comprehensively and intuitively,and evaluate the hemodynamic parameters better than traditional two-dimensional phase contrast MRI(2D PC MRI)and Doppler ultrasound,been gradually applied in the analysis of the intracranial,cardiac and other hemodynamics.The application and research progresses of 4D flow MRI for IA were reviewed in this article.
