Summary: Objective: To evaluate the ability of BMRI to detect silicone gel bleeding in a prospective observational study including consecutive patients referred for a BMRI scan.Methods: From January 2017 until now, patients referred for BMRI were evaluated in a prospective observational study. Patients who had breast implants were included. BMRI recorded 9 findings according to BI-RADS lexicon and SIGBIC findings, considered equivocal features to detect gel bleeding (GB). Three new original imaging features were added for SIGBIC diagnosis: black drop signal; T2* hypersignal mass; and delayed contrast enhancement, considered as irrevocable signs. The presence of silicones corpuscles was confirmed by percutaneous biopsy or surgical capsulectomy. The accuracy of BMRI SIGBIC findings to predict GB was determined. We also used univariate analysis for the equivocal features for GB diagnosis. The Backward method was applied for a multivariate Logistic Regression model for the equivocal features.
