영문 초록

Purpose The abdomen aorta computed tomography(CT) is uncomfortable to examinee, because of quickly injection of contrast media. So purpose is to adjust a present day’s dye amount, result from to decreased scan time for introducing the dual source CT. Materials and methods In the patients were prescribed abdomen aorta CT at this hospital from September 17th 2009 to February 22th 2010, we collected group A of 50 persons were used to dye of 12o±10ml, group B of 50 persons of the fresh amount to calculate and gained a distribution of each range, also the time of range with group A. In succession, we counted average moving time of dye from injection point to starting point of abdomen aorta+breath-hold time and the time required from enhance point to end of scan, so computed the optimum amount of dye & saline for scan and applied the figures targeting group B. Results We compared the group B and the group A, they are little difference in CT numbers. Ultimately, the exam is impossible to decrease dye of 33~45% than former amounts. Conclusion Through the research, we can decrease dye amounts for quickening scan time. It can make a positive influence to radiologist and patients, and anticipate the effect to cost reduction of dye.
