甲状旁腺的位置多变对能是造成甲状旁腺机能亢进患者手术切除不完全或未找到的原因,其结果为持续性高钙血症。10%甲状旁腺手术患者需行再次探查术,但手术更复杂,成功率较低,容易发生并发症。为此,作者建立了一种用~(131)I-甲苯胺蓝(RTB)甲状旁腺显像和~(99m)Tc过锝酸盐甲状腺显像叠加的方法。患者仰卧在γ照相机下,颈与针孔型准直器相距7～8cm,静脉注射~(131)I-RTB 481～555kBq(13～15μCi)/kg体重),1分钟后连续摄取甲状 Parathyroid changes in the location of the can cause hyperparathyroidism in patients with surgical excision is not completely or not found, the result is persistent hypercalcemia. 10% of patients with parathyroid surgery need to re-exploration, but the operation is more complicated, the success rate is lower, prone to complications. To this end, the authors established a method of 131I-toluidine blue (RTB) parathyroid imaging and ~ (99m) Tc percyanate thyroid imaging superposition. The patient was supine under a gamma camera, and the neck was separated from the pinhole collimator by 7-8 cm, intravenously 131I-RTB 481-555 kBB (13-15 [mu] Ci) / kg body weight)
