영문 초록

Purpose For this study we collected patients blood with performing CT exam before and after at our hospital and to research about radiation dose influence of blood cell count. Materials and methods The research object was implemented dynamic liver scan patient and blood analysis was performed with blood collected at CT exam before and after. In total 46 people(35 M, 11 Fe, mean age 57; range 30~77 years), weight ranged from 45kg to 112kg; mean 64kg, radiation dose ranged from 685mGy to 2,548mGy; mean 1,615mGy. The scan were performed with GE LightSpeed Ultra 16 Plus, Siemens Somatom Sensation 16, and blood analysis equipment using coulter counter theory, and sampling were used as EDTA tube. Blood examination value was compared with WBC, RBC, Hb, platelet, neutrophil, lymphocyte etc. Results WBC was decreased up to 46% compared to other cell. RBC cell was increased in 5 people and decreased in 41 people. Hb was increased up to 23% in 39 people and decreased in 7 people. Platelet was increased up to 13% in 35 people and decreased in 40 people. Neutrophil was increased up to 18.9% in 35 people and decreased in 40 people. Finally, lymphocyte was increased up to 6.6% but decreased 10.8% in 34 people. Conclusion Althougt we did not know the decrement or increase of the blood corpuscles whether radiation dose or not patient condition, but blood corpuscles count has varied in human body after CT examination. Further validation study is needed to know effect of radiation exposure to human body, because blood corpuscles is destroyed and newly born successively, and to understand about the precise process after radiation energy absorption.
