Bone scintigraphy is a highly sensitive but low-specific diagnostic method. It is noted that single-photon emission computed tomography combined with computed tomography (SPECT/CT) has greater sensitivity and accuracy compared to planar scintigraphy. The article presents differential diagnostics of focal bone changes detected by planar bone scintigraphy using clinical cases, carried out using the hybrid diagnostic method SPECT/CT, due to which benign changes in the skeletal system were detected. Thus, SPECT/CT examination allows to detect not only foci of malignant neoplasms, but also changes of benign nature, which is especially important in differential diagnostics of malignant and benign neoplasms.
