澳大利亚科学家首创了一有效因子,可用于癌肿的早期诊断.该因子是一复合物,介于锝~(99m)与边缘因子之间,它带有短暂的放射性,半衰期6个小时,该因子注入机体后,趋集于肿瘤部位,并放出γ射线.Jacobs博士指出,该因子适宜于早期诊断癌肿,尤其是内脏器官所遮掩的肿瘤;同时对于癌肿手术及药物治疗后的预后,该因子也能显示其价值.这一疗法相对现有的常规手段,如活检、超声波、X线、核共振等来说是一无创伤性的选择.锝~(99m)相当便宜,很容
Australian scientists pioneered an effective factor for the early diagnosis of cancer. The factor is a complex between 锝~(99m) and marginal factors. It has transient radioactivity and has a half-life of 6 hours. After injecting into the body, it converges on the tumor site and emits gamma rays. Dr. Jacobs pointed out that this factor is suitable for the early diagnosis of cancer, especially the tumors covered by internal organs. At the same time, for the prognosis after cancer surgery and drug treatment, Factors can also show its value. This therapy is a non-invasive alternative to existing conventional methods, such as biopsy, ultrasound, X-ray, nuclear resonance, etc. 锝 ~ (99m) is quite cheap, very capable
