The use of contrast agents in magnetic resonance (MR) studies of vascular pathology has permitted the exploration of regions that were heretofore poorly evaluated with conventional magnetic resonance angiography (MRA). An important feature of contrast-enhanced MRA (CE-MRA) is the very short acquisition times that are possible. The determination of the parameters to be used in a CE-MRA study rests on an understanding of the dynamics of the passage of the injected contrast agent and the response of the magnetization to the parameters of the MR imaging sequence. An overview of this interaction is presented.
在血管病理学的磁共振（MR）研究中使用造影剂，使得对以前用传统磁共振血管造影（MRA）评估不佳的区域进行探索成为可能。对比增强磁共振血管造影（CE-MRA）的一个重要特点是可以实现非常短的采集时间。CE-MRA研究中所用参数的确定取决于对注入造影剂的通过动力学以及磁化对MR成像序列参数的响应的理解。本文对这种相互作用进行了概述。
