作者报告在7年间作9860次~(131)I甲状腺显像中观察到的62例一侧甲状腺不显像的鉴别经验.7例确诊为一侧甲状腺不发育,55例为自主功能性甲状腺结节伴对侧甲状腺功能抑制.鉴别方法如下:用~(99m)Tc-过锝酸钠溶液370MBq作静脉内弹丸注射后,立即用带针孔准直器的γ照相机作动态显像,每3秒摄取一帧共20帧,以观察甲状腺的动脉血流.20分钟后再计数40万作静态显像.自主功能结节的甲状腺动脉血流表现为起初双侧均清楚.以后,功能受抑制的一侧放射性逐渐减
The authors reported 62 cases of thyroid imaging on one side in 9860 ~ 131 I thyroid imaging tests over 7 years, 7 cases were diagnosed as unthyred thyroid on one side and 55 cases were autonomic functional thyroid node Concomitant contralateral thyroid function inhibition.Distinguished as follows: ~ (99m) Tc-pertechnetate sodium solution 370MBq for intravenous injection, immediately with a pinhole collimator gamma camera for dynamic imaging, every 3 Second take a total of 20 frames in order to observe the thyroid artery blood flow.20 minutes and then re-count 40 million for static imaging .Functional nodules of the thyroid artery blood flow showed initially both sides are clear .Functionally inhibited The side of the radioactive gradually reduced
