Nodal Staging in Breast Cancer With MRL
The aim of this study is to examine the diagnostic performance of gadofosveset enhanced magnetic resonance imaging lymphography (MRL).
The diagnostic performance of MRL will be determined on the basis of a node-to-node matching of imaged nodes to the definitive histopathology. The pathologic examination of the sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) will be regarded as the golden standard for nodal involvement.

|Official Title:||Non-invasive Nodal Staging in Breast Cancer With Magnetic Resonance Imaging Lymphography Using Gadofosveset|
- The diagnostic performance (sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV)) of axillary MRL in predicting the involvement of metastases [ Time Frame: Participants will be followed from the moment of first out-hospital clinic vistit untill final breast surgery, an expected average of 4 weeks. ] [ Designated as safety issue: No ]The main study parameter will be the diagnostic performace (sensitivity, specificity, NPV and PPV) of the axillary MRL in predicting the involvement of metastases in the investigated lymph nodes. Each node will be scored on MRL as 0= benign, 1=malign. These results will be compared with the histopathological results of the SNLB procedure of ALND procedure on an node by node basis. So the diagnostic performace can be calculated.

|Experimental: Gadofosveset MRL||
Drug: Gadofosveset enhanced MRL of axillary lymph nodes
A MRL of the axilla will be performed before and after administration of a single IV bolus injection of gadofosveset of an equivalent of 0.03 mmol Gd/kg body weight at an injection speed of 1.5 mL/sec., followed by a saline flush of 25 mL at an injection speed of 1.5 mL/sec.
