摘要
目的 探讨SPECT采集放射性计数对断层积分法计算甲状腺体积的影响。方法 对 4例甲状腺触诊大小不同的甲状腺功能亢进患者进行各种不同采集计数显像 ,并计算甲状腺体积 ,然后进行比较。结果 不同采集计数会影响甲状腺体积的计算。结论 采集放射性计数一定要足够 ,对不同大小的甲状腺 ,采集的最小计数不同。
Objective To search the influence factor of acquisition counts on SPECT integral method for calculating thyroid volume. Methods Thyroid volume of various acquisition counts were performed in four patients with hyperthyroidism. And calculated thyroid volume was compared with palpable volume. Results Various acquisition counts influenced calculating thyroid volume. Conclusion Acquisition counts must be adequate in SPECT calculation. Minimum acquisition counts were various with different thyroid volume.
