Abstract:
Objective To explore the application and problems of using high pressure injection combine detaining needle in cere‐bral thrombosis on CT angiography in rabbit models .Methods 38 rabbit models were divided to experimental group and control group (19 cases each) .Rabbits in the experimental group were injected contrast medium into rabbit ear marginal vein with detaining needles and connected high pressure injection and the control group used intravenous infusion combined high pressure injection . Then observe the CT image quality and infusion outcome in two groups .Results There were 18 cases (94 .74% ) in the experimen‐tal group obtained successful infusion and excellent image quality ,and 13 cases (68 .42% ) in the control group got excellent image , the difference has statistical significance (Z = - 2 .099 ,P = 0 .036) .All of the images of experimental group showed thrombosis clearly .Conclusion High pressure injection combine detaining needle on CT angiography can increase test efficiency ,simplify the operation sequence and achieve evaluating goals .
