Abstract
Introduction: Bone is the most common site of hematogenous metastasis of malignant tumors. Patients with bone metastasis can have a series of bone related adverse events, which seriously affect the quality of life and survival time of patients. Imaging examination is the main means of clinical diagnosis and evaluation of bone metastasis. Aim of the Work: To evaluate the value of single-photon emission computerized tomography (SPECT) combined with CT and MRI in the diagnosis of bone metastasis of malignant tumors. Subjects and Methods: Eighty patients with bone metastasis from malignant tumors who were admitted to Affiliated Hospital of Chengde Medical College were selected from March 2019 to June 2021. They underwent bone scan with SPECT imaging, CT and MRI separately. The distribution of bone metastasis from primary tumors as well as efficacy of the above three detection methods for bone metastasis was analyzed. Results: A total of 464 lesions were detected by SPECT and CT in the same scanning field, with SPECT detection rate of 92.5% (429/464) and CT detection rate of 77.8% (361/464) (P < 0.05). In addition, 143 lesions were detected by SPECT beyond the same scanning field. A total of 321 lesions were detected by SPECT and MRI in the same scanning field, with SPECT detection rate of 95.6% (307/321) and MRI detection rate of 82.6% (265/321) (P < 0.05), and nother 286 lesions were detected by SPECT beyond the same scanning field. In all, 259 lesions were detected by CT and MRI scans in the wild same scanning field. The detection rate was 71.4% (185/259) for CT, and 95.7% (248/259) for MRI (P < 0.05). The ensitivity, specificity and accuracy of SPECT imaging combined with CT and MRI were higher than single SPECT imaging, CT and MRI (P < 0.05). Conclusion: SPECT may be the preferred screening modality for uspected bone metastases, and when combined with CT and MRI, it can clarify the regional distribution of bone metastasis from malignant tumors and improve the sensitivity, specificity and accuracy of diagnosis with high clinical significance.
