A bone scan and a computed tomography (CT) scan are both used to diagnose various bone conditions.

A CT scan is a high-resolution X-ray that gives detailed information about organ anatomy.
Bone Scan | Risks and After Effects | Patient
How does a bone scan work? Bone scans use radionuclides to detect areas of the bone which are growing or being repaired. A radionuclide (sometimes called a radioisotope or isotope) is a chemical which emits a type of radioactivity called gamma rays. A tiny amount of radionuclide is put into the body, usually by an injection into a vein.
