• Computed axial tomography (CAT or CT): imaging by a cross-sectional plane of the body; also called computed tomography. 
• Magnetic resonance imaging (MRI): a diagnostic radiologic test using nuclear magnetic resonance.
• Bone mass density (BMD): a measure of bone density or weight.
• Densitometry: measurement of bone thickness. 
• Ultrasonography is used to identify inflammation in joints or tendon tears. 
• Electromyography: a diagnostic test in which a small needle is inserted into muscle tissue and the electrical activity is recorded. 
• Biopsy is most effective in finding tumors of the musculoskeletal system.
