MR angiography allows the imaging of vessels comparable with the vessels imaged with digital angiography. MR-angiograms were also generated by image subtraction. Basis are the different magnetic properties of moved and stationary spins. Contrast media are not required. In recent years the various techniques of image subtraction with the aim of good imaged vessels were developed. The most important are described in this paper.
磁共振血管造影能够对血管进行成像，其成像效果可与数字血管造影所成的血管影像相媲美。磁共振血管造影图像也可通过图像减法生成。其原理是移动自旋和静止自旋具有不同的磁特性。无需使用造影剂。近年来，为了获得良好的血管成像效果，人们开发了各种图像减法技术。本文将介绍其中最重要的几种技术。
