Paget's disease is often incidentally discovered during routine X-rays or blood tests performed for another condition. For a definitive diagnosis and confirmation of the disease, comprehensive radiological imaging and specific blood tests are conducted following a doctor's examination. One of the primary methods commonly used in the diagnosis of Paget's disease is:

Bone Scintigraphy (Bone Scan)
This imaging technique involves injecting a low dose of a radioactive substance into the body. Scintigraphy helps identify areas of increased metabolic activity in the bones, thereby determining which bones are affected by the disease and their level of activity. This provides important information about both the condition of the bones and the body's metabolic turnover rate.
