目的:探讨术前99m Tc-甲氧异腈(MIBI)核素双时相显像与SPECT/CT融合显像在继发性甲状旁腺功能亢进症中的临床价值。方法:回顾分析经病理证实的38例继发性甲状旁腺功能亢进症患者术前99m Tc-MIBI核素双时相显像与SPECT/CT融合显像的影像资料。结果:99m Tc-MIBI核素双时相显像与SPECT/CT融合显像诊断继发性甲状旁腺功能亢进症的灵敏度分别为86.52%、95.74%;统计分析显示两者之间差异有统计学意义。结论:术前99m Tc-MIBI核素SPECT/CT融合显像对继发性甲状旁腺功能亢进症的评估优于核素双时相显像,SPECT/CT融合显像是继发性甲状旁腺功能亢进症术前定位理想的检查方法。
Objective: To explore the clinical value of dual-phase 99m Tc-sestamibi(MIBI) scintigraphy and SPECT/CT imaging in diagnosing secondary hyperparathyroidism. Methods: Retrospectively analyzed the image features of dual-phase 99m Tc-MIBI scintigraphy and SPECT/CT of 38 patients with secondary hyperparathyroidism, which were confirmed by postoperative pathology. Results: The sensitivity of 99m Tc-MIBI scintigraphy and SPECT/CT in diagnosing secondary hyperthyroidism was86.52% and 95.74% respectively. There were significant difference between dual-phase 99m Tc-MIBI scintigraphy and SPECT/CT.Conclusions: Preoperative99m Tc-MIBI SPECT/CT imaging is significantly better than dual-phase 99m Tc-MIBI scintigraphy in evaluating secondary hyperparathyroidism.99m Tc-MIBI SPECT/CT imaging is an ideal examination method for secondary hyperparathyroidism in preoperative location.
