Representative multidetector-row computed tomography lymphography (MDCT-LG) images of a 59-year-old woman with left primary breast cancer (stage pT3N1, Non-specific invasive breast cancer). A The MDCT-CT 3D reconstruction image showed an sentinel lymph node was in level I. B, C Sagittal and coronal MDCT-LG image showed this lymph node with oval shape, a long-axis diameter of about 13.3 mm, and a short-axisdiameter of about 11.1 mm (green arrows) and a cortical thickness about 4.3 mm (green arrows). The patient underwent both sentinel lymph node biopsy and axillary lymph node dissection, a total of eighteen lymph nodes were removed, and sentinel lymph node biopsy removed seven lymph nodes, four of which proved to be pathologic positive
