Abstract

Magnetic resonance images from 0.35T and 0.5T imaging systems are processed and evaluated in order to visualize and quantify blood flow. The velocity of moving substances is either measured by local and temporal tracking or by motion dependent encoding and decoding. With the first method the passage time through an imaged slice of known thickness may be measured. The signal intensity at an offset position also indicates how far a bolus has advanced under consideration of its velocity distribution. The second principle depends on MR gradient field encoding.
