COULD HEMODYNAMIC ANALYSES BLOOD FLOW SIGNAL BE HELPFUL IN PREDICTING LEVELS IN MRI

Computer simulations of hemodynamics were carried out on stenotic carotid and femoral arteries as well as their normal counterparts to acquire further insight into the cause of signal variations associated with blood flow in MRI. The simulation results were primarily analyzed in terms of the flow velocity distributions. The results were commensurate with those of previous MR phantom studies [l, 21 in that changes in the flow velocity patterns were significant downstream from the stenosis. This implies that if the results of the hemodynamic package are provided as input into a MR pulse sequence simulation program, the interrelationship between imaging parameters, disordered flow patterns, and signal loss may be better established.
