| Outline of Final Research Achievements |
Diagnostic system to distinguish cancerous area from keratotic lesion of oral mucosa was tested in this study. First of all, we examined a procedure using a high-frequency ultrasound with contrast agent in the experimental cancer model of mice. As a result, this procedure was useful in measuring the depth of cancerous lesion, but not so effective to evaluate two dimensional area of the cancer. To evaluate the area of cancer, we made the ICG encapsulated liposomes as a contrast agent, and then observed the experimental cancer model using a fluorescence stereomicroscope. From this observation, it was revealed that the fluorescence imaging using the ICG encapsulated liposomes is useful in the evaluation of the two dimensional area of the cancer.
