Mammography time risk of breast cancer from 1 mammogram. 40-49 y/o: 2/mil, 50-59 y/o: 1/mil. Risk of dying from Breast cancer, 40-49: 700/mil, 50-59: 1000/mil.
Life radiation risk
ConventionMarker (l/r/cc/mlo) always placed by axillary tail/lateral breast.
labeling of Breast radiographs
MLO view Depicts most tissue. Must visualize posterior nipple line (perpendicular line from pec through nipple) and inframammary fold.
CC view Pec visualized central on the film (only occurs at 30%) with nipple in profile at 1 cm from image edge.
Associated Fibrocystic Change. Fibrosis adenosis. Sclerosing adenosis. Epithelial hyperplasia. Cysts. Apocrine metaplasia. Atypical hyperplasia.
with indeterminate calcifications
Differential Hormone therapy (bilateral). Inflammatory cancer (skin thickening). Radiation therapy (at 6 months). Diffuse mastitis. Lymphatic/venous obstruction.
for increased breast density
Intracapsular versus Extracapsular implant Rupturefree. Mammography can't detect intracapsular silicone rupture (MR).
Intravascular: contained. Extravascular:
