Three-phase bone scintigraphy using technetium-99m-methylene diphosphonate is used to diagnose skeletal lesions, whereas single-photon emission computed tomography/computed tomography (SPECT/CT) improves the diagnostic accuracy of bone disease. We investigated the usefulness of SPECT/CT combined with three-phase bone scintigraphy over three-phase bone scintigraphy alone in assessing suspected bone tumors in patients with no malignant history. ⋯ Compared with three-phase bone scintigraphy, the diagnostic accuracy of SPECT/CT combined with three-phase bone scintigraphy was higher. SPECT/CT combined with three-phase bone scintigraphy is beneficial over three-phase bone scintigraphy for the differential diagnosis of suspected bone tumors in patients with no malignant history.
