Women's health news related to breast imaging, including mammography, breast MRI, automated breast ultrasound (ABUS), breast ultrasound, breast biopsy, and positron emission mammography (PEM). This channel also includes news on breast density and the issues it causes in detecting cancers. Mammography can be broken into two types of systems. 2-D full field digital mammography (FFDM) have almost completely replaced older X-ray film based systems. The newest generation systems use 3-D tomosynthesis mammography technology, where a series of digital images are shot in an arch around the breasts and a computer reconstructs the images into slices that can be scrolled through to see layers of tissue. This allows easier radiology reading of images, especially in women with dense breasts, because it can cancers where there are several layers of thick breast tissue that can mask cancers on 2-D mammography. Tomo is rapidly replacing FFDM.
Images show symptomatic false-negative cancer in a 73-year-old black woman who presented with a palpable abnormality 64 days after negative screening mammography. (a) Negative screening left digital breast tomosynthesis (DBT) mammogram. (b) Diagnostic DBT mammogram shows a new palpable mass (arrow). (c) Spot-compression DBT mammogram enables confirmation of mass (arrow). (d) Ultrasound (US) image shows hypoechoic mass with angular margins. Subsequent US-guided biopsy revealed estrogen receptor- and progesterone receptor-positive and human epidermal growth factor receptor 2-negative invasive ductal carcinoma.

Images in a 55-year-old woman with a spiculated mass localized in the upper central quadrant (arrow in A, B, D, and E) of right breast detected with digital breast tomosynthesis (DBT) plus synthetic mammography (SM). Breast density was classified as category C with the Breast Imaging Reporting and Data System. Mass was invasive ductal carcinoma, stage I, and was estrogen and progesterone receptor positive and human epidermal growth factor receptor 2 negative. A, Image from SM in craniocaudal view. B, Single-slice DBT image in craniocaudal view. C, Magnification of the lesion depicted in B. D, Image from SM in mediolateral oblique view. E, Single-slice DBT image in mediolateral oblique view. F, Magnification of the lesion depicted in E. Images courtesy of Radiological Society of North America
Mammograms in a 51-year-old woman with invasive ductal carcinoma. The upper panels show the craniocaudal and the mediolateral oblique views. The lower panels show a close-up of the left breast area containing the lesion. The case is one of the false-negative cases included in the dataset. Accordingly, the initial screening assessment was a BI-RADS 2, meaning visible findings were judged as benign. After 1 year, the patient presented for another screening examination. This time, a focal asymmetry with associated distortion within the left breast was noticed; the patient was recalled and diagnosed with a 1.5-cm mass in the upper outer quadrant of the left breast on the craniocaudal view (circle).
