Whole-body bone imaging shows active bone metabolism suggesting that bone reconstruction is accelerated or underway at the site, which may be the site of a fracture, a local infection, a primary tumor, or a metastatic bone tumor. Whole body bone imaging is to detect metabolic abnormalities in bone tissue by radionuclide, which can show certain lesions before X-ray and CT examination, and in the area of active bone metabolism is the site of coalescence and aggregation of radioactive material. If bone tissue lesions such as fractures, osteoarthritis,, bone tuberculosis, osteomyelitis, bone tumors, etc., after the destruction of the local bone, the bone tissue needs to be reconstructed to repair the location of the lesion, which is manifested as active bone metabolism. There are many conditions that cause active bone metabolism, it is recommended to consult a doctor in time for further examination, which needs to be combined with clinical signs and symptoms to determine the nature of the lesion with active bone metabolism.
