MRI BI-RADS 3 follow-upRepeat MRI at 6 months; if remains BI-RADS 3 then repeat at 12, 18, and 24 months; after 2 years of stability reclassify as BI-RADS 2 (benign)
Mammogram/US BI-RADS 3 follow-upRepeat the original study at 6 months; if still BI-RADS 3 repeat at 12, 18, and 24 months; after 2 years of stability classify as BI-RADS 2 (benign)
High‑risk MRI: Li‑Fraumeni (TP53)Start annual MRI at age 20
High‑risk MRI: BRCA1/BRCA2Start annual MRI at age 25
High‑risk MRI: STK11, PTEN, CDH1, NF1, PALB2, ATM, CHEK2Start annual MRI at age 30
High‑risk MRI: BARD1, RAD51C, RAD51DStart annual MRI at age 40
High‑risk lesions (ADH/ALH/LCIS)Start MRI at time of diagnosis but not before age 25
Prior chest radiationStart MRI at age 25 OR 8 years after completion of radiation therapy, whichever is later
Implant imaging — routine surveillance timingNo routine advanced imaging if <5 years after implant placement; initial imaging at >5 years with follow-up every 2–3 years after an initial negative study
Implant imaging — suspected rupture: salineIf exam equivocal: <30 yrs → ultrasound; 30–39 or ≥40 yrs → ultrasound or diagnostic mammogram; if indeterminate then breast MRI without contrast (CPT 77047)
Implant imaging — suspected rupture: siliconeAll ages: if asymptomatic and <5 yrs → no routine imaging; initial imaging at >5 yrs → ultrasound (MRI without contrast CPT 77047 if ultrasound indeterminate); if exam equivocal → ultrasound OR MRI without contrast (CPT 77047)
