What role should MRI play in breast cancer screening and management?

The increasing use of magnetic resonance imaging in breast cancer screening and management of early breast cancer is a ‘hot-button' issue.

Superficially, it sounds like a good idea. MRI of the breast is a highly sensitive test, especially useful in uncommon clinical scenarios such as Paget's disease of the breast or occult primaries.

In high-risk patients with BRCA1 and BRCA2 gene mutations, detection of malignant breast lesions increases from 25-59% with mammography alone to 80-100% when combined with MRI.1

Annual MRI screening among BRCA carriers detects more interval cancers and more earlier-stage cancers (ductal carcinoma in situ and stage I carcinoma, 13.8% with MRI vs 7.2% without MRI).2

Adding annual MRI screening to mammography also results in 70%
