(A) Mammographic magnification view shows grouped calcifications in the left breast (circle). Stereotactic biopsy yielded grade 2 DCIS. Patient underwent a lumpectomy with tumor-negative surgical margins and radiation therapy. (B) Mammographic magnification view obtained four years after diagnosis shows new calcifications at the surgical site (circle). Stereotactic biopsy was performed, which revealed recurrent grade 2 DCIS. The patient then underwent a mastectomy. Image courtesy of the ARRS.

FES-PET better than FDG-PET in breast cancer patients
By Will Morton
In a head-to-head comparison, F-18 fluoroestradiol (FES)-PET/CT was better than standard FDG-PET/CT for the initial staging of estrogen receptor-positive breast cancer patients.

New AI training strategies stiffen defense against adversarial attacks
By Liz Carey
Computer scientists are exploring how to protect against medical errors caused by adversarial attacks on AI machine learning diagnostic models.
December 15, 2023
An illustration of two types of adversarial attacks on breast imaging diagnosis. Adversarial noise applied in white-box attacks and adversarial samples produced by generative adversarial networks in black-box attacks can fool a deep learning diagnostic model to give wrong output, according to University of Pittsburgh researchers. The researchers have proposed two security schemes, called ARFL and LIDA, to make the models robust and resilient to adversarial attacks.

DBT plus mammo detects breast cancers with higher histologic grades
By Amerigo Allegretto
Digital breast tomosynthesis (DBT) plus synthesized mammography screening leads to higher detection of early-stage invasive breast cancers grades 2 or 3.
December 6, 2023
Imaging depicts a screen-detected invasive breast cancer in the dense breast tissue of a 59-year-old woman. A section in the mediolateral oblique view from a DBT exam of the left breast shows an irregular mass with surrounding architectural distortion (circle). The participant had no history of breast cancer and had been screened previously in the German mammography screening program. Histologic analysis showed invasive carcinoma of no special type, grade 2, with tumor size of 18 mm. Image courtesy of the RSNA.
