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．
Application of parathyroid imaging, and confirmed by surgery and pathology in 17 patients with primary hyperparathyroidism. We used two 201T and 99mTC-MIBI two parathyroid imaging agents and 201T1 / 99mTcO4-, 99mTc-MIBI / 99mTcO4-subtraction method and 99Tc-MIBI dual-phase method of three imaging methods. The pathological results of 17 patients were 15 cases of parathyroid cancer (1 case of multiple, 2 adenomas), 1 case of cancer and 1 case of hyperplasia. Parathyroid imaging accurate positioning of 17 glands, 1 case of false negative. This case is located in the anterior superior mediastinum parathyroid adenoma, visual field did not include the upper chest and missed diagnosis. The accuracy of positioning was 94.1% (94.4% by gland number). Fifteen of the 17 patients underwent B-mode ultrasound examination before operation. Three adenomas were not found. The accuracy of localization was 86.7% (81.3%). Because the countdown is limited, the accuracy of the three imaging methods can not be compared, but the 99mTC-MIBI dual-phase method is the simplest for patients or operators.
