Abstract

The objective of this paper is to describe the basic physical principles important in magnetic resonance angiography (MRA). The data used were obtained from recent articles on MRA retrieved from Index Medicus 1985-92 and direct experience working with prototype MRA sequences. The information is presented in a manner suitable for those unfamiliar with the principles of MRA and magnetic resonance imaging (MRI). Magnetic resonance angiography is an important method that can be used to obtain angiograms without the injection of intravascular contrast medium. It is already proving to be of clinical use in the assessment of vascular disease.

摘要

本文的目的是描述磁共振血管造影（MRA）中重要的基本物理原理。所使用的数据来自1985 - 1992年从《医学索引》检索到的关于MRA的近期文章以及使用MRA原型序列的直接经验。信息以适合不熟悉MRA和磁共振成像（MRI）原理的人的方式呈现。磁共振血管造影是一种重要的方法，可用于在不注射血管内造影剂的情况下获得血管造影图像。它已被证明在评估血管疾病方面具有临床应用价值。
