We evaluated the role of second look US for the study of occasional lesions detected on preoperative breast MRI and we proved it can
be an helpful way to localize and study lesions depicted only on preoperative breast MRI.

Transfer constant obtained from DCE-MRI are well correlated with tumor size and histologic grade of breast cancer, which shows its
potential as a noninvasive prognostic parameter in the breast cancer patient.

We think that in patient with DCIS, complemented MRI may be best establish the presence and extent of disease.

This pilot study demonstrates the accuracy of dynamic contrast-enhanced (DCE)-MRI and diffusion-weighted (DW)-MRI in detecting
and localising multifocal and multicentric disease in patients with breast cancer by correlating imaging with histopathology findings at
mastectomy. DCE-MRI alone was most accurate in detecting satellite lesions (sensitivity of 89%), DW-MRI was least accurate
(sensitivity 55%). Satellite lesions were found up to 22 mm from the edge of the index lesion. Accurate identification of satellite
lesions with multifunctional MRI offers potential for monitoring the effects of local therapies on multifocal and multicentric disease,
and in defining the target volume for partial breast irradiation.

The presence of axillary lymph node(LN) metastases in breast cancer is an important factor in assessing prognosis and determines
management. Although surgical biopsy remains the gold standard for the diagnosis of axillary LN metastasis but standard for surgical
biopsy in monitoring for chemotherapy response does not established yet. Comprehensive and sequential staging of axilla using
noninvasive diagnostic modalities has been approached and which would represent an importance advance in the management of
breast cancer patients. This presentation evaluate the accuracy of comprehensive pre- and post-neoadjuvant chemotheraphy axillary
staging via MRI, ultrasound imaging and positron emission tomography.

We would like to submit our report titled ¡°MRI Findings of Triple Negative Breast Cancer: A Comparison with Non Triple Negative
Breast Cancer¡¯¡¯. Triple negative breast cancer is a subtype with aggressive clinical behavior which currently lacks effective targeted
