光动力疗法(Photodynamic therapy,PDT)的应用是传统癌症治疗理念上的又一项突破性成就,它是利用肿瘤组织选择性吸收光敏剂后,经特定波长的激光照射病变部位,使肿瘤组织中的光敏剂发生光化学反应,从而达到选择性治疗的目的。PDT可广泛应用于药械或多种手术联合治疗,进一步地提高治疗效果。光动力诊断(Photodynamic disgnosis,PDD)是指特定的光照射一定的光敏物质后产生的一系列化学、物理、生物等反应用于诊断肿瘤的一种方法。光
Photodynamic therapy (Photodynamic therapy, PDT) is another breakthrough in the concept of traditional cancer treatment, it is the use of selective absorption of tumor tissue photosensitizer, the specific wavelength of laser irradiation lesions, so that tumor tissue Of the photosensitizer photochemical reactions, so as to achieve the purpose of selective treatment. PDT can be widely used in medicine or a variety of surgical treatment, and further improve the treatment effect. Photodynamic disgnosis (PDD) refers to a series of chemical, physical, and biological reactions that occur after a specific light irradiates a photosensitive substance to diagnose a tumor. Light
