Diagnostic Tests Flashcards
radiograph that visualizes injected dye in an artery; used to identify arteriosclerosis, tumors, blockages
arteriography
invasive test utilizing contrast medium to provide visualization of joint structures through radiographs; identified by leakage from the joint cavity and capsule
arthrography
utilizes radioactive isotopes to identify stress fractures and tumors
bone scan
produces cross-section images; used to diagnose spinal lesions and in diagnostic studies of the brain
computed tomography (CT scan)
noninvasive test that evaluates blood flow in the major veins and arteries; relies on transmission and reflection of high frequency sound waves to produce cross-sectional images
doppler ultrasonography
recording of the electrical activity of the heart; identifies conduction abnormalities, cardiac arrhythmias, cardiac arrhythmias, and myocardial ischemia
electrocardiography
recording of electrical activity of the brain
electrocephalography
recording of the electrical activity of a muscle or muscle groups; used to assess peripheral nerve injuries
electromyography
designed to show motion in joints through x-ray imaging; not commonly used due to excessive exposure
fluoroscopy
utilizes magnetic fields to produce an image of bone and soft tissue; valuable in providing images of soft tissue structures
expensive and requires pt to remain still for prolonged periods of time
magnetic resonance imaging MRI
used to identify bone displacement, disk herniation, spinal cord compression or tumors
injection of a contrast dye into the spinal canal (CSF) in order to enhance Xray or CT imaging of the spine
myelography
visualizes injected dye in a vein; can be used to identify tumors or blockages in the venous network
venography
radiographic photograph commonly used to assist with diagnosis of musculoskeletal problems such as fractures, dislocations, and bone loss
X-ray
