"Optimal Radiolabeled Liposomes for Tumor Imaging."

According to the authors' abstract of an article published in Journal of Nuclear Medicine, "We conducted a systematic study of the effects of liposome formulation and encapsulated radionuclides on imaging ability. Methods: Various types of liposomes were prepared and labeled with Ga-67, In-111, or Tc-99m. Their tumor-imaging potential was evaluated in terms of tumor accumulation and tumor-to-blood ratios of radioactivity delivered by the liposomes. Mouse sarcoma 180 and Ehrlich solid tumor were the tumor models. Results: Liposomes could be labeled rapidly and with high efficiency, which was sufficient for clinical application. Tumor accumulation of...
