血液流动对MR成像的影响

Effect of Blood Flow in MR Imaging Medical

本文讨论了血液流动对ＭＲ成像的影响。它们是图像伪影的来源，在血管造影中，它们用于显示血管和提供关于血液流动速度的信息。流动对两个方面的影响敏感，第一质子群的流入和流出。第二流动产生的相位移。

This paper discussed the effect of blood flow in MR imaging. It is a source of image artifacts. In MR angiography, it is used to display vessels and provide information regarding the blood flow velocity. Flow sensitivity is primarily on two effects. First the inflow and outflow of spin ensembles. Second flow induced phase shifts. In addition to introducing Gradient motion rephasing.
