[Visualization of abdominal arteries by super-high-flow venous injection using multidetector helical CT]

The purpose in this study was to compare the ratio of visualization of upper abdominal arteries using MDHCT between the super-high-flow injection method (Group A) and the conventional injection method (Group B). The subjects ects were 200 patients who were randomly divided into Group A (100 patients) and Group B (100 patients). In Group A, visualization of the large arteries, including the CE, SMA, HA and LGA, was possible at a rate exceeding 96%, and that of the small arteries, including the DPA, SPDA, RGA and Cyst A, was more than 79%. Visualization of upper abdominal arteries was markedly improved by the super high flow injection technique.
