Consideration needed in breast cancer screening for young women
By Amerigo Allegretto
A study presented at the ARRS annual meeting suggests that consideration is needed for breast cancer screening in women younger than 40 years.
May 21, 2024
Images of a 39-year-old woman shows a grade 2 invasive ductal carcinoma on mammography, confirmed by supplementary ultrasound. Mammography detected an asymmetry with calcifications while ultrasound examination revealed a hyperechoic mass. The resulting sentinel lymph node biopsy was negative.
Breast imaging AI algorithm influenced by patient characteristics
By Amerigo Allegretto
Patient characteristics influenced false-positive results on DBT when analyzed by an FDA-approved AI algorithm.
May 21, 2024
An example mammogram was assigned a false-positive case score of 96 in a 59-year-old Black patient with scattered fibroglandular breast density by an FDA-approved AI algorithm. (A) Left craniocaudal and (B) mediolateral oblique views demonstrate vascular calcifications in the upper outer quadrant at middle depth (box) that were singularly identified by the algorithm as a suspicious finding and assigned an individual lesion score of 90. This resulted in an overall case score assigned to the mammogram of 96.
