We evaluated 85Sr/89Sr SPECT with CT attenuation correction (CTAC) and SPECT/CT fusion images using SPECT/CT system. CTAC using SPECT/CT system could improve image quality of 85Sr/89Sr SPECT, however, could not increase detectability of bone metastasis. In 85Sr/89Sr SPECT-CT fusion images, we could easily realize the location of abnormal uptakes that were unclear in SPECT images only. 83Sr/89Sr SPECT imaging using SPECT/CT system would be useful for detecting the more detailed whole body 89Sr distribution than SPECT system imaging.
