【摘要】 应用甲状旁腺显像，并经手术及病理确诊１７例原发性甲状旁腺机能亢进患者．我们采用了２０１ＴＩ和９９ｍＴＣ－ＭＩＢＩ互两种甲状旁腺显像剂及２０１Ｔ１／９９ｍＴｃＯ４－、９９ｍＴｃ－ＭＩＢＩ／９９ｍＴｃＯ４－减影法和９９Ｔｃ－ＭＩＢＩ双时相法三种显像方法．１７例的病理结果为１５例甲状旁腺癌（１例为多发，２个腺瘤），１例癌及１例增生．甲状旁腺显像准确定位１７个腺体，１例假阴性．此例系位于上纵隔主动脉前方的异位甲状旁腺瘤，显像时视野未包括上胸部而漏诊．定位准确率为９４．１％（按腺体数计为９４．４％）．１７例中１５例术前也进行了Ｂ超检查，３个腺瘤未发现，定位准确率为８６．７％（８１．３％）．由于倒数有限，无法比较三种显像方法的准确率，但９９ｍＴＣ－ＭＩＢＩ双时相法无论对于病人或操作者均最简单易行．更多还原

【Abstract】 Abstract cases of primary hyperparathyroidism wre studied by parathyroid imaging and confirmed surgically and pathologically.Two parathyroid imaging agents,201TI and 99mTc-MIBI,and three methods,201TI/99mTc pertechnetate,99mTc-MIBI/99mTc pertechnetate subtraction imaging and 99mTc-MIBI double-phase study were used. Among the 17 cases,the pathological results showed 16 parathyroid adenomas(1 case with 2 adenomas),1 carcinoma and 1 hyperplastic gland.The parathyroid imaging correctly predicted the sites of 17 glands and missed one.In the latter case,the adenoma located in the upper mediastinum just in front of the aorta,but during the imaging process,the upper portion of the thorax had not been included in the field of view.The overall detection rate was 94.1% (94.4%).15 of 17 cases were also studied by ultrasonography.Three adenomas were missed, the detection rate being 56.7%(81 .3%).Due to the limited number of cases,it is difficult to make comparison between different methods.However,the 99mTc-MIBI double-phase study seems to be most easy to perform both for the patients and for the operators.更多还原
