Preoperative MRI displays additional disease in 10.4% of cases in patients with infiltrating ductal carcinoma.
In cases with a complex intraductal-associated component, MRI is helpful in managing the surgical approach, and can potentially reduce reoperation rates.
Preoperative MRI showed a 91.9% agreement with the final histology, but core-needle biopsy cannot be rejected, so as to limit unnecessary surgery.
When MRI shows additional disease, there is often a change in the initial surgical plan.
Evolving surgery techniques, such as oncoplastic procedures, can be safely performed as an alternative to mastectomy in some patients.
