| Research Abstract |
The aim of the present study is to develop a real time diagnostic method of lymphatic metastasis less than 1cm in diameter. First we developed the color difference based on standard deviation (CDSD)method. Next we succeeded in extracting vascular structures in the tumors of less than 1 cm in diameter by high-frequency ultrasound (HF-US)system, nanobubbles (NBs), and the CDSD method. We applied the methodology to the lymphatic metastasis model, and found that it was applicable to early diagnostic and treatment evaluation of lymphatic metastasis.
