Question Answer
AnteriographyRadiograph that visualizes injected radiopaque dye in an artery.
Used to identify arteriosclerosis, tumors or blockages
ArthrographyInvasive test utilizing a contrast medium to provide visualization of joint structures through radiographs.
Soft tissue disruption can be identified by leakage from the joint cavity and capsule
Bone ScanInvasive test that utilizes isotopes to identify stress fractures, infection, and tumors.
Can identify bone disease or stress fractures with as little as 4-7% bone loss
Computed tomographyProduces cross-sectional images based on x-ray attenuation.
Commonly used to diagnose spinal lesions and in diagnostic studies of the brain.
Dopplet ultrasonographyNon-invasive test that evaluates blood flow in the major veins, arteries, and cerebrovascular system.
ElectrocardiographyRecording electrical activity of the heart.
Used to help identify conduction abnormalities, cardiac arrhythmias, and myocardial ischemia.
ElectroencephalographyRecording of the electrical activity of the brain.
Used to assess seizure activity, metabolic disorders, and cerebellar lesions.
ElectromyographyRecording of the electrical activity of a selected muscle or muscle groups at rest and during voluntary contraction.
Commonly used to assess peripheral nerve injuries and to differentiate between various neuromuscular disorders.
FluroscopyDesigned to show motion in joints through x-ray imaging. This technique permits objects placed between a fluorescent screen and a roentgen tube to become visible. Not used commonly due to excessive radiation exposure.
Magnetic Resonance Imaging (MRI)Non-invasive technique that utilizes magnetic fields to produce an image of bone and soft tissue.
Provides images of soft tissue structures such as muscles menisci, ligaments, tumors, and internal organs.
MyelographyInvasive test that combines fluoroscopy and radiography to evaluate the spinal subarachnoid space.
Used to identify bone displacement, disk herniation, spinal cord compression or tumors.
VenographyRadiograph that visualizes injected radiopaque dye in a vein.
Used to identify tumors or blockages in the venous network.
X-rayRadiographic photograph commonly used to assist with the diagnosis musculoskeletal problems such as fractures, dislocations, and bone loss.
