摘要
目的比较Ｂ超、ＣＴ、９９ｍＴｃ甲氧基异丁基异腈（ＭＩＢＩ）对于高功能甲状旁腺病灶定位诊断的价值。方法经临床诊断为原发性甲状旁腺机能亢进（简称原发甲旁亢）的２３例患者均做了Ｂ超检查，２０例做了ＣＴ扫描，２１例进行了９９ｍＴｃＭＩＢＩ核素显像。结果２３例患者共摘除２３枚腺瘤和２枚增生腺体，均经病理诊断证实。Ｂ超、ＣＴ、９９ｍＴｃＭＩＢＩ的灵敏度分别为６０％、６８％和９１％，特异性为９７％、９７％和１００％，准确性为８９％、９１％和９８％。Ｂ超与ＣＴ无明显差异，９９ｍＴｃＭＩＢＩ在灵敏度和准确性方面优于Ｂ超和ＣＴ，但特异性三者近似。结论９９ｍＴｃＭＩＢＩ双时相法对于甲状旁腺腺瘤的定位诊断很有帮助。
Purpose To evaluate the values of ultrasound, CT and 99m Tc MIBI in the localization of hyperfunctioning parathyroid tissue Methods 23 patients with primary hyperparathyroidism underwent 23 ultrasound, 20 CT scans and 21 double phase 99m Tc MIBI imagings Surgical and histological correlation was obtained for all studies Results 23 adenomas and 2 hyperplastic glands were removed from 23 patients The results showed the sensitivities were 60%, 68%, 91%; the specificities were 97%, 97%, 100%; and the accuracies were 89%, 91%, 98% respectively with ultrasound, CT and 99m Tc MIBI There was no significant difference between ultrasound and CT (P>0 05), but 99m Tc MIBI was superior to ultrasound and CT in the sensitivity and accuracy, the specificity was similar for all of three imaging methods (P>0 05) Conclusions Double phase 99m Tc MIBI imaging is a promising technique for localization of parathyroid adenomas It is necessary for patients to undergo the noninvasive imaging procedures before their initial neck exploration
