摘要
肝脏血流受其复杂的血管解剖结构、较慢的血流速度和人体呼吸运动等因素的影响,运用超声、CT和二维相位对比MRI(two dimensional phase contrast MRI,2D PC MRI)进行评估较为困难.四维血流MRI(four dimensional flow MRI,4D Flow MRI)不仅能够对肝脏复杂的血流分布进行可视化研究,还能对其血流动力学异常进行量化分析,是评估肝脏血流动力学的重要影像学工具.本文主要介绍4D Flow MRI的技术原理及其目前在肝脏疾病中的应用研究,以期为临床了解相关疾病的病情进展及疗效评估提供更全面的影像学依据,为未来的研究方向提供参考.
Abstract
Liver blood flow is affected by its complex vascular anatomy, slow blood flow velocity, and human respiratory movement, which is difficult to evaluate liver blood flow by ultrasound, CT, and two dimensional phase contrast MRI (2D PC MRI). Four dimensional flow MRI (4D Flow MRI) can not only visualize the complex blood flow distribution of the liver, but also quantify hemodynamic abnormalities, which is an important imaging tool for evaluating liver hemodynamics. This article mainly introduces the technical principle of 4D Flow MRI and its current application in liver diseases, in order to provide a more comprehensive imaging basis for clinical understanding of the disease progression and efficacy evaluation of related diseases, and provide reference for future research direction.
