Paper Abstract

Digital radiographic flow patterns were analyzed during series of pulsed contrast bolus injections in both phantoms and canine arteries. The effects of stenoses in the phantoms and canine vessels on the flow patterns were also studied. Our digital radiographic results indicate that it is possible to determine the velocity of flow by the pulsatile injection mode and that the large variations in flow patterns observed is a strong function of the elastic properties of the flexible phantoms or arteries as well as of the degree of stenosis. Both cardiac gating and choice of injection site proved important in the canine studies. Work is underway to extend these results to NMR.
