Table 1 Common Indications for Breast MRI in suspected/known breast malignancy

Adenocarcinoma of unknown primary – suspected occult breast malignancy

Local staging – Clinical/imaging size discrepancy

 Difficulty sizing with conventional imaging – suspected multifocality

 Invasive lobular carcinoma, dense breasts

 Non-calcified DCIS

 Potential candidate for accelerated partial breast irradiation or IORT

Response assessment (neoadjuvant chemotherapy)

Lesion characterisation/problem solving

Residual disease post wide local excision

Differential diagnosis of local recurrence and treatment effects

Screening of high risk groups (BRCA mutation carriers, previous mantle radiotherapy)
