Abstract
Magnetic Resonance Imaging (MRI) has the ability to visualize blood flow noninvasively and without contrast agents, since the MR signal depends not only on the spin-density and the relaxation times T1 and T2, but also on the velocity of the moving spins itself. Besides the magnitude image a phase image, which is highly sensitive to motion, can be calculated from the complex signal after the Fourier transform. With the magnitude as well as the phase information conclusions about the flow characteristics and the velocity profile can be made, which is particularly important for instance for the diagnosis of aneurysms and stenoses [1].
