BI – RADS 장점


판독의 표준화
영상의학과 의사와 임상 의사간의 오해의
소지를 없애고, 의사소통을 원활하게 하기
위해 다소 정형화된 용어를 사용

낭종과 고형 종괴의 구분
유방 촬영술상 치밀 유방에서 보이지 않지만 만져지
는 병변의 검사
병변의 위치로 인해 유방 촬영술에서 충분이 검사할
수 없는 종괴
유방 촬영술상 유방암의 위험도가 높고 치밀유방인
환자에서 숨은 병변을 찾기 위해
젊은 여성에서 만져지는 유방 종괴의 검사
임산부나 수유부의 일차 검사
국소적 유방 통증 및 압통 등의 증상이 있는 환자에
서 정확한 원인 규명
