Magnetic resonance (MR) angiography is a powerful tool for the evaluation of cervical and intracranial vasculature. Both noncontrast and contrast-enhanced MR angiography can provide exquisite vascular contrast and detail without the use of ionizing radiation. More advanced techniques such as time-resolved MR angiography and parallel imaging provide dynamic information in rapid fashion. This article describes the basic principles and techniques of MR angiography image acquisition.
磁共振(MR)血管造影是评估颈部和颅内血管系统的有力工具。非增强和增强磁共振血管造影均可在不使用电离辐射的情况下提供清晰的血管对比度和细节。时间分辨磁共振血管造影和平行成像等更先进的技术能快速提供动态信息。本文介绍了磁共振血管造影图像采集的基本原理和技术。
