核医学与超声检查对亚急性甲状腺炎的诊断价值

目的利用核医学检查与超声诊断技术提高亚急性甲状腺炎（SAT）的诊断准确率。方法实验组随机选择61例SAT患者,核医学实验室检测血清FT3、FT4、TSH,甲状腺6h摄碘率（RAIU/6h）,并进行甲状腺核素扫描,所有患者均行超声检查。另设30例正常人作为对照组仅行甲状腺超声检查。结果以TH与RAIU/6h呈分离现象或核素显像阳性为依据,核医学实验室诊断SAT阳性率为95.1%（58/61）,超声诊断阳性率为81.9%（50/61）,核医学诊断阳性率明显高于超声检查（P〈0.05）,两种检查方法相结合诊断率达100%.甲状腺超声测定结果表明实验组甲状腺明显大于正常对照组（P〈0.05）。结论核医学检查与超声检查相结合,有利于提高SAT的诊断准确率。

The Clinical Value of Nuclear Medicine and B-Ultrasonic on Subacute Thyroiditis

Objective To study the clinical value of nuclear medicine and B-ultrasonic on subacute thyroiditis(SAT).Methods All sixty-one persons with SAT were examined by nuclear medicine,including thyroid hormone,TSH,the rate of radioiodine uptake at 6 hours(RAIU/6h) and nuclide imaging on thyroid.Persons with SAT and 30 normal healthy persons were all examined by B-ultrasonic.Results The positive rate of SAT was 95.1%(58/61)examined by nuclear medicine according to nuclide imaging or the TH level which was disobedient to RAIU/6h.The positive rate of SAT was 81.9%(50/61)by B-ultrasonic examination.There was an obvious difference in the positive rate of SAT examined by the two different methods(P<0.05).And the positive rate of SAT was nearly 100% examined by both nuclear medicine and B-ultrasonic at the same time.The thyroids of SAT were much larger than normal judged by B-ultrasonic(P<0.05).Conclusion It is very important to combine nuclear medicine and B-ultrasonic to improve the diagnosis of SAT.
