Fig. 1. Breast image of a 53-year-old woman. (A, B) Mammography did not demonstrate any abnormal lesions in the heterogeneously dense breast. (C, D) Breast specific gamma imaging demonstrated focal increased radiotracer uptake in the upper outer quadrant area (arrow) of the right breast. (E) Ultrasound demonstrated an ill-defined hypoechoic nodule at 9 h of the right breast (arrow). Pathology demonstrated an 8-mm focus of invasive ductal carcinoma.
