A variety of methods has been developed for quantitating flow in vivo. These are usually based on the principles of velocity-phase or TOF information. The former allows a point-by-point 2D image of velocity, but also has other manifestations involving real-time ID projections or ID projections with ID velocity information (flow/eugmatography). The TOF methods use the inflow of unsaturated spins into a saturated region (for example) to estimate flow. The concepts, features, and clinical applications of these and other techniques are reviewed in this article.
