Imaging localization and diagnosis of sentinel lymph node of breast cancer

Sentinel lymph node (SLN) has significant clinical value in diagnosing axillary lymph node of early breast cancer. Combining with indirect lymphography, ultrasound, CT and MRI can show lymphatic vessels, therefore SLN can be localized through capturing the relationship between SLN and lymphatic vessels. All these imaging techniques, especially the magnetic resonance lymphography, provide new methods in evaluating SLN. (authors)
