electromyogram (EMG)
a neurodiagnostic graphic record of the electrical activity of muscle at rest and during contraction to diagnose neuromusculoskeletal disorders
-
magnetic resonance imaging (MRI)
a nonionizing imaging technique using magnetic fields and radiofrequency waves to visualize anatomical structures
-
nuclear medicine
ionizing imaging technique using radioactive isotopes
-
radionuclide organ imaging
bone scan
-
bone scan
radionuclide imaging of bone tissue to detect tumor malignancy
-
radiography
x-ray imaging; an ionizing technique commonly used in orthopedics to visualize the extremities, ribs, back, shoulders, joints, etc.
-
arthrogram
an x-ray of a joint taken after injection of a contrast medium
-
diskogram
an x-ray of an intervertebral disk after injection of contrast medium
-
dual-energy x-ray absorptiometry
an x-ray scan that measures bone mineral density of the spine and extremities to diagnose osteoporosis, determine fracture risk, and monitor treatment
- Classifications of bone mass include:
- - normal
- - osteopenic
- - osteoporotic
-
computed tomography (CT)/computed axial tomography (CAT)
a specialized x-ray procedure producing a series of cross-sectional images that are processed by a computer into a 2-dimensional or 3-dimensional image
-
sonography
ultrasound imaging; a nonionizing technique useful in orthopedics to visualize muscles, ligaments, displacements, and dislocations or to guide a therapeutic intervention such as that performed during arthroscopy
