甲状旁腺功能亢进的定位诊断

比较了８５例临床诊断为甲状旁腺功能亢进的患者使用（２０１）Ｔｌ／（９９ｍ）Ｔｃ双核素减影技术、（９９ｍ）Ｔｃ－ＭＩＢＩ和Ｂ型超声做病灶术前定位的结果。术中共发现９９个病灶，双核素显像检出４９个病灶，Ｂ超发现６７个病灶，灵敏度分别为５０％和６７％。其中８例患者用（９９ｍ）Ｔｃ－ＭＩＢＩ检查的灵敏度为６７％（６／９）；对异位甲状旁腺病灶核素显像的灵敏度为８４．６％（１４／１７），Ｂ超为４１％（７／１７）。

Pre-operative Localization of Lesions in Hyperparathyroidism

Tl/99m Tc parathyroid subtraction scintigraphy and echography were used in 85 patients with clinical hyperparathyroid syndrome for preoperative localization of parathyroid lesions,49 and 67 lesions were identified by scintigraphy and by echography respectively in a total of 99 lesions which were found by surgery.There were no false positive in scintigraphy and 14 false positive in echography, In summary the sensitivity was 50%for scintigra phy and 67%for echography. For lesions in the ectopic glands the sensitivity is 84.6%(14/17) and 41%(7/17) respectively. The sensitivity of MIBI is 67%(6/9).
