Abstract: 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.
