Is a one-year follow-up an efficient method for better management of MRI BI-RADS® 3 lesions?

Our results suggest that a one year follow-up instead of two years is sufficient for BI-RADS 3 lesions, in case of using rigorous inclusion criteria. Given the very low PPV of the BI-RADS® 3 lesions incidentally found on MRI, further studies with very large inclusions are necessary to establish new guidelines for MRI follow-up.
