甲状旁腺功能亢进其实并不少见,临床表现变幻奠测,术前定位诊断困难。自从有了扫描定位以来,作者一直考虑给予改良,现介绍一种~(201)铊与~(99)锝注射彩色对比扫描定位方法,并在经手术等方法证实的74例1评价中,证实其高敏感性与特异性。74例中甲状旁腺腺瘤57例,原发性腺体增生10例,继发性腺体增生(均为慢性肾衰)6例,甲状旁腺癌1例。方法是病人仰卧,双侧前臂伸展至套管内呈“蝴蝶状”,先注射2～3mCi(74～111mBq)的~(201)氯化铊,15分钟内铊积储量平均为45000,用 r 扫描照相。然后再注射5～10mCi(185～370mBg)~(99)锝,平均积
It is not uncommon for parathyroid glands to become hyperactive, clinical manifestations change, and it is difficult to diagnose preoperatively. Since the scanning location has been considered, the author has been considering to give improvements. Now we introduce a method of color contrast scanning and localization of ~(201)铊 and ~(99)锝, and confirm it in 74 cases of 1 evaluation confirmed by surgery and other methods. Its high sensitivity and specificity. In 74 cases, there were 57 cases of parathyroid adenomas, 10 cases of primary glandular hyperplasia, 6 cases of secondary glandular hyperplasia (all chronic renal failure), and 1 case of parathyroid carcinoma. The patient was supine. The bilateral forearms stretched into a “butterfly-like” shape within the cannula. First ~2m (3mCi) (74 ~ 111mBq) of ~(201) guanidinium chloride was injected. Within 15 minutes, the average reserve was 45,000. Take photos. Then inject 5 to 10 mCi (185 to 370 mBg) to (99) tantalum.
