    • Disclosed is a method of therapy used in combination with a diagnostic tool for enhanced photodynamic therapy using MRI, called (magnetic resonance imaging)-guided photodynamic therapy. The methods of the present invention includes administration of MRI contrast agent labeled polymer photosensitizer conjugates, detection and localization of tumor or cancer tissues with contrast-enhanced MRI and specific illumination and treatment of localized target tissues, such as tumors or cancer cells, using laser energy. The delivered laser energy activates the photosentizer accumulated in the target tissue, resulting in treatment. Also disclosed are novel conjugate compounds, such as PLGA-Mce 6 -DOTA-Gd complexes, having multi-functionality in that the complex may include an MRI contrasting agent linked to a photosensitizing agent.
    • 公开了一种治疗方法,与用于使用称为(磁共振成像) - 光导光疗法的MRI的增强光动力疗法的诊断工具结合使用。 本发明的方法包括施用MRI造影剂标记的聚合物光敏剂缀合物,使用对比度增强的MRI和特定照明的肿瘤或癌组织的检测和定位以及使用激光能量的局部靶组织如肿瘤或癌细胞的治疗 。 递送的激光能量激活积聚在靶组织中的光敏剂,从而进行治疗。 还公开了具有多官能度的新型缀合物化合物,例如PLGA-Mce 6-DTA-Gd络合物,因为该复合物可包括与光敏剂连接的MRI对比剂。
