[Determination of pathological margin of hypopharyngeal cancer by terahertz time-domain spectroscopy system]
Objective: To investigate the terahertz system accuracy in distinguishing hypopharyngeal cancer from normal tissue and its role in determining the pathological incised margin of hypopharyngeal cancer. Methods: hypopharyngeal cancer transplantation model in BALB male 5-week-old / c nude mice was established by subcutaneous injection. transplanted tumor specimens obtained pathologically diagnosed to determine the extent of the tumor tissue. tumor tissue, normal tissue and tumor tissue […]
