项目摘要
(1)Development of positron probe for intra-operative applicationApollomec corporation developed positron probe with two types of detectors, plastic scintillator for beta rays and BGO crystal for gamma rays. This probe counts as a real event only when both rays are detected simultaneously in order to reduce background level.(2)Committee on clinical application of radioisotopeOur protocol in clinical application is planned to measure radioactivity by positron probe during operation after injection of ^<18>F-FDG in P3 room just before operation. Therefore, the influence to the human body of ^<18>F was evaluated in above-mentioned committee. As a result, the committee approved the usage of ^<18>F, because that half life is very short and the influence to the human body is very little.(3)Examination of injection time of ^<18>F-FDGAs a matter of fact, to delay to start operation is needed to inject ^<18>F-FDG just before operation, because it takes a time to synthesize and purify ^<18>F-FDG. Therefore, we examined whether radioactivity of ^<18>F could be measured or not when ^<18>F-FDG was injected in the evening of the day before operation. The half life of ^<18>F is 109.8 minute. Theoretically, radioactivity is reduced to about 1/256, assuming to measure after 16 hours of injection. We measured radioactivity by gamma probe next morning in patients of esophageal squamous cell carcinoma with huge lymph node metastasis, however, its count was very subtle, so that this protocol of previous day injection was found not to be clinically applicable. Above all, the necessity of injection of ^<18>F-FDG just before operation was suggested to maintain diagnostic quality and accuracy by positron probe.Conclusion : A lot of issues to have to be resolved are still remained, however, FDG-guided surgery may be the promising new approach to have a potential as a breakthrough of quality of surgery.
(1)开发用于术内应用程序的正电子探针,开发了具有两种类型的探测器的正电子探针,用于β射线的塑料闪烁体和用于伽玛射线的BGO晶体。仅当同时检测到两种射线以降低背景水平时,该探测器才将其视为真实事件。(2)计划在临床应用中临床应用临床应用委员会委员会在注射 ^<<18后运行期间通过正电子探测测量放射性。 >在操作前,在P3室中的F-FDG。因此,在上述委员会中评估了对 ^<18> F的人体的影响。结果,委员会批准了 ^<18> F的使用,因为半寿命很短,对人体的影响很小。(3)检查注射时间 ^<18> f-fdgas a事实上,需要延迟开始操作才能在操作前注入 ^<18> f-fdg,因为它需要一些时间来合成和净化 ^<18> f-fdg。因此,我们检查了在操作前一天晚上注入 ^<18> f-fdg时是否可以测量 ^<18> F的放射性。 ^<18> F的半衰期为109.8分钟。从理论上讲,放射性降低至约1/256,假定注射16小时后测量。第二天早晨,我们通过γ型鳞状细胞癌的患者通过伽马探针测量了放射性,但淋巴结转移巨大,但是它的计数非常微妙,因此发现该前一天注射方案在临床上不适用。最重要的是,建议在操作之前注入 ^<18> f-fdg,以通过正电子探针维持诊断质量和准确性。结论:仍然存在许多必须解决的问题,但是,FDG引入了FDG手术可能是有可能具有手术质量突破的新方法。
