摘要
近十年来,三维冠状动脉成像技术的图像信躁比和空间分辨率明显提高,为冠状动脉的无创检查提供了一种安全可靠的手段。西门子公司在1.5和3.0T系统上都提供了靶容积与全心扫描的冠状动脉成像序列,作者主要针对全心冠状动脉成像的技术进行介绍。
Magnetic resonance coronary angiography (MRCA) is a noninvasive method of coronary arteries imaging. In the past decade, three-dimensional (3D) coronary artery MR imaging sequences have become the major approach because they provide volumetric coverage of the coronary arteries with high SNR and spatial resolution. Siemens provides both targeted (single or two main branches) and whole-heart coverage for coronary MRA imaging. This article imroduces the technical background of the whole-heart coverage and the scan procedures at 1.5 T and 3.0 T.
