Purpose A lot of hospitals use Contrast Medium mixed with Normal Saline when they operate CT study. This brings about cut down in expenditures as well as reduction of artifact in Subclavian vein. This thesis try to mearsure CT Number in the syringe when they were used mixed clinically, and to come up with right method of using those Contrast Medium, and Normal Saline. Materials and Methods We used the same materials and equipment as an actual CT Study. We used UltraVist300 as Contrast Medium, NaCl 0.9% for Normal Saline, and the ratio of Contrast Medium and Normal Saline is 1:1, 1:2, and 2:1 respectively. At the experiment, we measured CT Number in 200ml-syringe and measured the changed of CT Number for ten minutes, which is similar amount of time as the actual experiment. We used SIEMENS Somatom Sensation 16, and measured with Sequence Mode lOmm. ROI was 1cm/sq at the measurement. To distinguish Normal Saline from Contrast Medium, we put 1ml of blue ink into Normal Saline. Results At the Chest examination, it is beuer to pour Contrast Medium first and then Normal Saline later. When we put Normal Saline first and Contrast Medium later, it is diluted by just pouring them together. At all the experiments, when turned upside down, it shows the sTable distribution. At all the experiments, the CT Number show the highest at the lowest level. Conclusion We have checked CT Number in the syringe when we had experiment using Contrast Medium adding Normal Saline. Through this experiment, we could find out the mixed degree of Contrast Medium and Normal Saline that had been able to be checked only by naked eyes. Based on the results above, it is expected to apply it in an appropriate density. At the future research, based on the result above, I would like to find out the ideal CT Scan Start Time when the Artifact comes th the least at Image by finding out the time Contrast Medium is poured into Subclavian vein with flow rate, total volume of Contrast Medium and Normal Saline and the pouring pressure.
