- •The added benefit of MRI for evaluation of extent of disease is greater in ILC than IDC.
- •In ILC, MRI shows 80-90% concordance with pathology in defining extent of disease.
- •When discordance with pathology occurred, mammography and US more commonly underestimated and MRI more commonly overestimated extent of disease.
- •Pre-operative MRI should be considered for patients with ILC
- •Pre-operative MRI may decrease underestimation of disease extent and potentially contribute to a reduction in post-operative residual disease in IDC patients.
