흉부영역에서 디지털 토모신테시스의 유용성 평가

국문 초록 (Abstract)

흉부영역에서 토모신테시스 검사의 유용성 평가를 위하여 흉부단순검사와 저 선량 CT, 토모신테시스를 실시하여 흡수선량을 비교하고 영상을 평가하였다. 흉부단순검사의 흡수선량은 0.33±0.27 mGy 이었으며, 저 선량 CT는 1.26±0.56 mGy, 토모신테시스는 0.55±0.02 mGy로 검사별 흡수선량 간에 유의한 차이를 보였다(p<0.001). 영상의 평가결과 단순검사 점수는 각각 1.66±0.72, 1.61±0.63, 1.57±0.73 이었으며 저 선량 CT는 2.92±0.26, 2.91±0.29, 2.88±0.32 이었고, 토모신테시스는 2.69±0.51, 2.76±0.43, 2.66±0.61로 검사에 따라 통계적으로 유의한 차이를 보였으나(p<0.001), 저 선량 CT와 토모신테시스 사이에는 유의한 차이를 보이지 않았다. 토모신테시스는 흉부영역의 검사 시 환자의 피폭선량을 최소화하고 진단의 효과를 높일 수 있는 유용한 검사라고 생각된다.

To evaluate the usefulness of tomosynthesis in the chest area, simple radiograph, low-dose CT, and tomosynthesis examinations were performed, and their absorbed doses were compared, and finally the images were evaluated. The absorbed dose recorded with the simple Radiograph examination was 0.33±0.27 mGy, that of low-dose CT 1.26±0.56 mGy, and that of tomosynthesis 0.55±0.02 mGy, which indicate significance differences in absorbed doses among the examinations(p<0.001). Based on the evaluations of the images, The simple radiograph scores were 1.66±0.72, 1.61±0.63, and 1.57±0.73, respectively; low-dose CT scores were 2.92±0.26, 2.91±0.29, and 2.88±0.32, respectively; and tomosynthesis scores were 2.69±0.51, 2.76±0.43, and 2.66±0.61, respectively. That is, there were statistically significant differences among the examinations(p<0.001), although there was no significant difference between low-dose CT and tomosynthesis examinations. Therefore, tomosynthesis is judged to be a useful examination that can minimize radiation doses to patients during chest examinations and enhance diagnostic efficacy.
