Question | Answer |
Arteriography refers to a | radiograph that visualizes injected radiopaque dye in an artery. The test can be used to identify arteriosclerosis, tumors or blockages. |
Arthrography is an | invasive test utilizing a contrast medium to provide visualization of joint structures through radiographs. |
Arthrography Soft tissue disruption | can be identified by leakage from the joint cavity and capsule. Arthrography The test is commonly used at peripheral joints such as the hip, knee, ankle, elbow, and wrist. |
A bone scan is an invasive test that | utilizes isotopes to identify stress fractures, infection, and tumors. Bone scans can identify bone disease or stress fractures with as little as 4-7% bone loss. |
Computed tomography produces | cross-sectional images based on x-ray attenuation. A computerized analysis of the changes in absorption produces a detailed reconstructed image. |
Computed tomography | The test is commonly used to diagnose spinal lesions and in diagnostic studies of the brain. |
Doppler ultrasonography is a . | non-invasive test that evaluates blood flow in the major veins, arteries, and cerebrovascular system |
Doppler ultrasonography | The test relies on the transmission and reflection of high frequency sound waves to produce cross-sectional images in a variety of planes. |
Doppler ultrasonography | is safer, less expensive, and requires a shorter time period than more invasive tests such as arteriography and venography. |
Electrocardiography is the recording of | the electrical activity of the heart. |
Electrocardiography The test identifies three distinct waveforms: | P wave (atrial depolarization), QRS complex (ventricular depolarization), and the T wave (ventricular repolarization). Electrocardiography is used to help identify conduction abnormalities, cardiac arrhythmias, and myocardial ischemia. |
Electromyography is the recording | of the electrical activity of a selected muscle or muscle groups at rest and during voluntary contraction. |
Electromyography is performed by | inserting a needle electrode percutaneously into a muscle or through the use of surface electrodes. |
Electromyography The test is commonly used to | assess peripheral nerve injuries and to differentiate between various neuromuscular disorders. |
Fluoroscopy is designed to | show motion in joints through x-ray imaging. |
Fluoroscopy The technique | permits objects placed between a fluorescent screen and a roentgen tube to become visible. Fluoroscopy is not used commonly due to excessive radiation exposure. |
Magnetic resonance imaging is a | non-invasive technique that utilizes magnetic fields to produce an image of bone and soft tissue. |
Magnetic resonance imaging | The test is valuable in providing images of soft tissue structures such as muscles, menisci, ligaments, tumors, and internal organs. |
Magnetic resonance imaging requires the patient to | remain still for prolonged periods of time and is extremely expensive. |
Myelography is an | invasive test that combines fluoroscopy and radiography to evaluate the spinal subarachnoid space. |
Myelography The test utilizes a | contrast medium that is injected into the epidural space by spinal puncture. Myelography is used to identify bone displacement, disk herniation, spinal cord compression or tumors. |
Venography refers to a | radiograph that visualizes injected radiopaque dye in a vein. The test can be used to identify tumors or blockages in the venous network. |
X-ray is a radiographic photograph commonly used to . | assist with the diagnosis of musculoskeletal problems such as fractures, dislocations, and bone loss |
X-ray produces | planar images and as a result often requires images to be taken in multiple planes in order to visualize a lesionʼs location and size. |
