Abstract
The major method for sentinel lymph node (SLN) navigation is using radioisotopes and blue dyes. In addition to these, (99mTc-phytate, patent blue V dye), we performed preoperative CT-lymphography (CTLG) in 28 patients (12 men, 16 women). CTLG clearly visualized the draining lymphatics and SLNs in 17 out of 28 patients. We can detect the lymphatic flows and SLNs near the tumor without the influence of shine-through, especially in the head and neck regions. It is considered that CTLG is useful to determine the range of lymph node dissection.[Skin Cancer (Japan) 2012 ; 27 : 171-178]
