Learning objectives
Breast ultrasonography is the primary important modality in making a diagnosis of breast cancer.
Today,
breast Magnetic Resonance Imaging(MRI) is increasingly being used in work up of breast cancer patients.
Breast MRI has high sensitivity,
so it is useful in detection of malignancy and determine extent of breast cancer.
In addition,
other parts are also included on breast MRI : lungs,
mediastinum,
bone and the upper abdomen.
The purpose of this presentation is to review the unexpected extra mammary findings seen on the preoperative breast...
Background
Equipment and Positioning of Breast MRI
MR device with a field of strength of 1.5T or greater
A double breast surface coil
The patients lies prone with both breasts hanging into the surface coil
Imaging between days 7-14 of the menstrual cycle is recommendedto reduce back ground parenchymal enhancement
Indications of Breast MRI
Assessment of lesion extent in patients with known breast cancer
Monitoring of the response to neoadjuvant chemotherapy
Characterization of equivocal findings at conventional mammography and USG
Screening in high risk women
Examination...

Conclusion
The abnormalities detected on the extramammary structures may influence the staging and provide a clue to systemic metastasis,
which results in the change of treatment strategy.
So we must pay attention not only breast and axilla,
but also other structures included on breast MRI.
