The Role of Magnetic Resonance Imaging in Assessment of Axillary Lymph Nodes Metastasis in Breast Cancer Patients.

"The axillary lymph nodes will be evaluated on axial Time 1-weighted images obtained without fat saturation. We will measure the largest dimension and cortical thickness of each lymph node and ratio of the two measurements will be calculated.~The lymph nodes seen in Time 1-weighted images will be subsequently identified on the diffusion-weighted images to calculate the apparent diffusion coefficient value of each lymph node.~Axillary lymph nodes scanned by magnetic resonance imaging will be compared by results of histopathological examination."
