Abstract

Unlike conventional radiographic examinations, angiointerventional procedures have a high risk of radiation exposure to patients or operators due to prolonged radiation exposure time. This study was undertaken to examine effects of reducing the radiation risk by applying dose reduction fiber (DRF) shielding cloth during angiography. To investigate the properties of DRF shielding cloth, we measured the scattered radiation below and above a human phantom using a glass dosimeter, at site distances 10 cm away from the irradiated field. The results obtained reveal a 15 ~ 31% reduction of scattered radiation in the irradiation field, and 53 ~ 70% reduced radiation measured after phantom transmission. Taken together, our data indicate that application of DRF shielding cloth for radiation reduction at non-procedural sites during interventional procedure results in reduction of scattered doses to patients and operators, without affecting the medical examinations. We propose the use of DRF shielding during angiointerventional procedures, in order to reduce the risk of radiation exposure of patients and operators.

혈관 조영술과 중재적 시술은 진단을 위한 일반적인 방사선 검사와 다르게 낮은 관전류를 사용함에도 불구하고 장시간의 방사선 피폭으로 인해 환자나 시술자의 방사선 노출에 의한 위험도가 높다. 이에 본 연구의 목적은 선량저감섬유 (Dose Reduction Fiber, DRF) 차폐포를 사용하여 환자와 시술자의 피폭 선량을 증가 시키는 원인 중 하나인 산란방사선의 차폐를 통한 피폭 선량 감소 효과를 알아보고자 하였다. 선량저감섬유(DRF) 차폐포의 산란 방사선에 대한 차폐 효과를 알아보기 위해 방사선이 조사되는 조사야 밖 10 cm거리와 방사선의 인체 팬텀 투과 후 시술 부위 10cm 거리의 산란선량을 선량저감섬유(DRF) 차폐포 사용 전후로 유리 선량계를 이용하여 측정하였고, 조사야부에서 환자에게 조사된 방사선 중 불필요한 산란선량이 15~31%, 팬텀을 투과 후 시술부위에서는 발생한 산란선량이 53~70% 저감하는 효과를 확인 하였다. 선량 저감섬유(DRF)차폐포를 중재적 시술 시 비 시술 부위의 산란선 차폐제로 이용하면 의료 검사에는 영향을 주지 않으면서 산란선량을 줄여 환자와 시술자의 피폭 선량을 저감할 수 있다는 결과를 얻게 되었고, 이는 향후 혈관 조영술과 중재적 시술 시 선량저감섬유(DRF) 차폐포를 활용하여 환자와 시술자의 피폭선량경감을 통한 방사선 노출 위험의 경감을 기대할 수 있을 것으로 보인다.
