^(99m)TC—MIBI鼻咽癌阳性显像的探讨

Detection of Positive Image of Nasopharyngeal with Tc-99m MIBI

目的用(~99m)Tc-MIBI来探索鼻咽癌的原发灶和转移灶的诊断.资料与方法 用(~99m)Tc-MIBI断层显像检测21例对照组和41例治疗前鼻咽癌病例,病灶的放射性摄取与头皮比较,由3名以上的医师在不知道任何临床情况下分别阅片.结果41例治疗前鼻咽癌病例中共有36例阳性.特异性为91%,灵敏度为88%.结论用(~99m)Tc-MIBI来探索鼻咽癌的原发灶和转移灶的诊断,是一种灵敏的,值得进一步探讨的影像学方法.

Purpose:We prospectively study patients with nasopharyngeal carcinoma(NPC) to determine the efficacy of Tc-99m MIBI scintigraphy in detecting the primary tumors and metases.Materials and methods: 21 health adullt voluteers and 41 NPC patients.The images were visually assessed by comparing the nasopharyngeal uptake relative to scalp radioactivity. Conclusion: This study suggests that 99m-MIBI SPECT to ke useful for detecting NPC and have potential value in diagnosis of recurrent NPC.
