From: An investigation of tomosynthesis on the diagnostic efficacy of spot compression mammography
A 39-year-old woman with invasive ductal carcinoma confirmed via excision biopsy. (a,b) Full-field digital mammography shows a vague mass in the lower center of the left breast. (c) Conventional spot compression view shows a high-density mass with an obscured margin, categorized as Breast Imaging Reporting and Data System (BI-RADS) 4A. (d) Spot compression tomosynthesis clearly shows a spiculated margin (arrow); thus, the lesion was categorized as BI-RADS 4C.
