A three-dimensional Fourier transform magnetic resonance imaging technique is presented. This procedure can be used to selectively detect flowing material such as blood in arteries and veins. Since flow is detected in a manner in which velocity-induced phase shifts are compensated, signal loss arising from complex flow and turbulence is minimized. The flow image is sensitive to all velocity components of flow. Applications of this technique are limited, however, to relatively straight vessels having appreciable flow. Examples of application of this technique to healthy and diseased carotid arteries are shown.
本文介绍了一种三维傅里叶变换磁共振成像技术。该方法可用于选择性检测诸如动脉和静脉中的血液等流动物质。由于检测流动的方式是对速度引起的相移进行补偿，因此复杂流动和湍流引起的信号损失被降至最低。流动图像对流动的所有速度分量都很敏感。然而，该技术的应用仅限于具有明显流动的相对笔直的血管。文中展示了该技术在健康和患病颈动脉上的应用实例。
