Transcript BI - RADS
BI – RADS (breast imaging reporting and data system) 영상의학과 전민정 BI – RADS 장점 판독의 표준화 영상의학과 의사와 임상 의사간의 오해의 소지를 없애고, 의사소통을 원활하게 하기 위해 다소 정형화된 용어를 사용 판독 Tool Indication for examination Breast composition • The breast is almost entirely fat • There are scattered fibroflandular densities • The breast tissue is heterogeneously dense • The breast tissue is extremely dense Findings Comparison to previous studies Overall impression(classification category) 유방촬영 findings Mass Calcification Special cases A. Mass Shape Margin Density A. Mass A. Mass A. Mass B. Calcification Typical benign Intermediate concern calcification • Amorphous or Indistinct calcifications Higher probability malignancy • Pleomorphic calcification • Linear branching (Casting) calcification • Fine linear or fine pleomorphic microcalcification C. Special cases Solitary dilated duct Intramammary lymph node Focal asymmetric density US Indications 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 유방 초음파 findings Mass Calcifications Special cases Vascularity A. Mass Shape Orientation Margin Echo pattern Posterior acoustic features A. Mass-Shape A. Mass-Margin A. Mass-Echo Pattern A. Mass-Orientation A. MassPosterior Acoustic Features B. Calcifications Macrocalcifications Microcalcifications • Microcalcifications Out of a Mass • Microcalcifications In a Mass C. Special Cases : Unique diagnosis or finding Clustered microcysts Complicated cysts Mass in or on skin Foreign body Lymph node-intramammary Lymph node-axillary D. Vascularity Present or not present Present immediately adjacent to lesion Diffusely increased vascularity in surrounding tissue BIRADS-Assessment Categories Assessment is Incomplete • Category 0 : Need Additional Imaging Evaluation Assessment is Complete – Final Categories • Category 1 : Negative • Category 2 : Benign Finding • Category 3 : Probably Benign Finding • Category 4 : Suspicious Abnormality • Category 5 : Highly Suggestive of Malignancy • Category 6 : Known Biopsy-Proven Malignancy
