Abstract

The aim of this study is to compare reference levels for radiation dose in angiography and interventional radiology. Proposed reference levels for various procedures and classification of diseases are provided by fluoroscopy time and kerma area product(KAP) rate normalizing the body habitus focusing the cerebrum. Subarachnoid hemorrhage(SAH) represents the highest KAP-rates and aneurysm represents the lowest KAP-rates. According to these types of procedures, internal carotid artery(ICA), common carotid artery(CCA), and vertebral artery(VA) show the highest KAP-rates and guglielmi detachable coil shows the lowest KAP-rates. Therefore, the present study can suggested reference levels for patient radiation dose and is expected to be further useful in the field of radiation dose education and management of angiography and interventional radiology.

혈관 조영 검사 및 중재적 방사선 시술을 통한 환자에게 주어지는 피폭선량에 대해 대뇌를 중심으로 환자 체형을 표준화하여 검사 및 시술 차이에 따른 투시시간, 면적 선량률(kerma area product rate)을 관측하고 참고 기준치를 비교하고자 하였다. 그 결과 질병 분류에 따른 면적 선량률은 지주막하출혈(subarachnoid hemorrhage)이 가장 높았고, 뇌동맥류가 가장 낮았다. 또한 검사 및 시술에 따른 면적 선량률은 양쪽 내경동맥, 양쪽 총경동맥 및 추골동맥으로 하는 방법이 가장 높았으며, guglielmi detachable coil(GDC)이 가장 낮게 나타났다. 따라서 이를 혈관 조영 검사 및 중재적 방사선 시술시 환자 피폭 선량에 대한 참고 기준치로 이용할 수 있을 것이며 향후 환자 피폭 선량 교육과 관리에 유용할 것이라 사료된다.
