| 目的 探讨应用韧致辐射监测介入核素在人体甲状腺及其它部位的分布及其可行性。方法 ①以2 个相同规格分别装有约14.8MBq 的32 P 胶体及99m Tc 的玻璃瓶为模型,进行32 P 能谱、窗宽实验。②对介入治疗后甲状腺进行32 P 显像,并与99m Tc 甲扫图比较。结果 ①32 P 模型韧致辐射能谱为一连续曲线,其顶峰能量约为83keV ,最佳窗宽为60 %。②用实验的能量参数在人体可得到理想的32 P 韧致辐射图像。结论 利用韧致辐射显像能够监测治疗用放射性药物在体内的分布状况。 |

| Objective To monitor the distribution of interventional radionuclide in thyroid and other areas in human bodyby bremsstrahlung phenomenon and evaluate the credibility of this method. Methods ①2 similar glass bottles filled withsome 14.8MBq 32 P colloid and 99mTc fluid respectively were used as experimental models. 32 P bremsstrahlung spectrum andenergy windows was measured. ②32 P bremsstrahlung imagings of thyroid were performed after interventional nuclide theraphy and they were compared with 99m Tc thyroid scans. Results ①32 P bremsstrahlung spectrum of the model is a continualcurve and its highest energy peak is about 83 keV. The optimum energy window is 60 %. ②The ideal 32 P bremsstrahlungimaging of human body would be gotten with above factors. Conclusion It's practicable to monitor the distribution oftherapeutic radiopharmaceutical in human body utilizing bremsstrahlung imaging technology. |
