甲状腺功能显像中^（99m）Tc摄取率的临床价值

Clinical evaluation of ^(99m)Tc uptake rate in functional image of thyroid

测定了１０１例甲状腺病患者３、２４ｈ１３１Ｉ摄取率和３０ｍｉｎ９ｍＴｃ摄取率，还测定了２２例甲状腺正常者３０ｍｉｎ９９ｍＴｃ摄取率．结果是甲状腺正常的３０ｍｉｎ摄９９ｍＴｃ率为３．７３±１．５６；摄９９ｍＴｃ率在正常值以上的患者，其摄９９ｍＴｃ率与摄１３１Ｉ率的临床符合率为８２．４％．在正常值以下的患者，其摄９９ｍＴｃ率与摄１３１Ｉ率的临床符合率为９１．３％．在正常值范围的患者其摄９９ｍＴｃ率与摄１３１Ｉ率的临床符合率为８８．５％。研究表明．摄９９ｍＴｃ率诊断甲状腺功能比摄１３１Ｉ率更方便。

The 3,24 h 131I and 30 min 99mTc uptake rates have been measured in 101 cases with thyroid disease. The 30 min 99mTc uptake rate was also measured in 22 cases with normal thyroid.The results showed that 30 min 99mTc uptake rate of normal thyroid were 3.73±1.56.The coincident rate of increased value in 99mTc uptake with fall uptake were 82.4%,while those of decreased and normal value were 91.3% and 88.5% respectively.Above studies have shown that in functional image of thyroid 99mTc uptake is more useful than 24h 131I uptake test.
