In this Wednesday talk, researchers will present findings from their study of nearly 2,700 women that used a convolutional neural network in predicting mammographic density percentage from MRI scans.

Bas van der Velden, PhD, from University Medical Center Utrecht will talk about how the deep-learning tool (VolparaDensity version 1.5, Volpara Health) showed high specificity in correctly triaging more than half the number of women with decreased breast density, switching them from receiving MRI-only screening to receive mammographic screening.

The team included 4,300 MRI exams and trained their network through two screening rounds.

"AI-based triaging of women with extremely dense breasts from MRI-only screening back to mammography screening is feasible, enabling radiologists to reduce workload and reallocate resources," the study authors wrote.
