目的本研究比较99Tcm-MIBI/99TcmO4-显像减影法与其他影像方法对术前甲状旁腺瘤定位诊断的价值,并探讨腺瘤大小、重量、血PTH及血钙对此核素显像的影响。方法回顾性分析了17例病理证实为甲状旁腺腺瘤患者,术前均行此核素显像及B超,其中15例行CT,10例行MRI检查。结果核素显像的灵敏度为70.59%,高于B超(58.82%)、CT(66.67%)及MRI(50.00%)。在核素显像阳性组(n=12)之腺瘤重量明显大于阴性组(n=5),差异具有统计学意义(P<0.05);组间腺瘤最大径、血清PTH及血钙无统计学差异。结论99Tcm-MIBI/99TcmO4-显像减影法在术前甲状旁腺腺瘤的定位诊断中具有重要价值。
Objective This study compared 99Tcm-MIBI / 99TcmO4-imaging subtraction and other imaging methods for the preoperative diagnosis of parathyroid tumor, and to explore the adenoma size, weight, blood and serum calcium PTH nuclide imaging Impact. Methods A retrospective analysis of 17 cases of pathologically confirmed parathyroid adenoma patients, preoperative imaging of this radionuclide and B ultrasound, of which 15 cases of CT, 10 cases of MRI. Results The sensitivity of radionuclide imaging was 70.59%, higher than that of B ultrasound (58.82%), CT (66.67%) and MRI (50.00%). The adenoma weights in the group of positive radionuclide imaging (n = 12) were significantly higher than those in the negative group (n = 5) (P <0.05). The maximum diameter of adenomas, serum PTH and serum calcium Statistical differences. Conclusion The 99Tcm-MIBI / 99TcmO4-imaging subtraction method is of great value in the localization and diagnosis of preoperative parathyroid adenoma.
