目的:探讨~(131)I SPECT/CT断层融合显像在分化型甲状腺癌诊治检测中的临床价值.材料和方法:选择术后病理证实并接受~(131)I治疗的分化型甲状腺癌(DTC)患者97例,行~(131)I全身扫描(~(131)I-WBS)和病灶部位的SPECT断层加同机CT融合显像.将~(131)I-WBS与断层融合图像进行对比分析,探讨断层融合显像的特点与临床价值.结果:97例分化型甲癌患者共进行~(131)I-WBS 251次,断层融合显像102次,每例患者至少行一次断层融合显像.与~(131)I-WBS比较,断层融合显像有如下特点:①能够获得直观的断层融合显像和三维立体图像;②发现更多的病灶;③更准确地判断病变部位;④定位CT可以发现无摄碘功能的病灶;⑤鉴别病灶和生理显影或污染.结论:~(131)I SPECT/CT断层融合显像可以直观病变立体形态、大小、摄取程度和毗邻关系,在鉴别病灶与生理显像或污染、确定病灶是否有摄碘功能方面有重要价值,是~(131)I-WBS的重要补充.

Purpose The clinical advantages of ~(131)I SPECT/CT fusion imaging over planar imaging of differentiated thyroid cancer(DTC) were studied. Materials and Methods 97 DTC accepting ~(131)I therapy after thyroid surgery underwent planar ~(131)I whole-body scan(WBS) and SPECT/CT fusion imaging. The diagnostic performance of ~(131)I-WBS and SPECT/CT were comparatively analyzed. Results The patients had totally 251~(131)I-WBS and 102 SPECT/CT imaging. In comparison to WBS, SPECT/CT fusion images were proven of a few advantages, such as: (1)Fused and 3D images being obtained by SPECT/CT;(2)finding more focus;(3)correctly confirming the position of lesions;(4)locating some ~(131)I negative lesions;and (5)distinguishing physiological or polluted activity. Conclusion ~(131)I SPECT/CT fusion imaging could clearly reveal the shape、sizes、biological status and relation to surrounding tissues, thus providing additional information to ~(131)I-WBS in DTC.
