  • Abstract
  • Look Inside

The appearance of flowing blood can be evaluated using magnetic resonance imaging (MRI). Depending on the velocity and direction of the flow, flowing blood has a variable appearance in MR images. Rapidly flow-ing blood which runs perpendicular to the imaging plane shows no signal (high velocity signal loss). Slow laminar flow has a stronger signal to the adjacent tissue when blood vessels run perpendicular to the imaging plane (flow related enhancement), and so when blood vessels course within the imaging plane (even echo rephasing).
