Which diagnostic test produces cross-sectional images based on x-ray attenuation
and is commonly used to diagnose spinal lesions and in diagnostic studies of the
brain?
fluoroscopy
computed tomography
bone scan
magnetic resonance imaging
Give this one a try later!
computed tomography
Computed tomography produces cross-sectional images based on x-ray
attenuation and is commonly used to diagnose spinal lesions and in
diagnostic studies of the brain. A computerized analysis of the changes in
absorption produces a detailed reconstructed image.
,What are the black areas produced on a radiograph called?
radiodense
radiolucent
radiopaque
radio waves
Give this one a try later!
radiolucent
Dense objects such as bone and metal fragments display brighter because
they block more of the beam, therefore reducing the films exposure.
Objects that block X-rays are said to be radiopaque, whereas those that
pass X-rays are radiolucent and produce black areas.
What non invasive test evaluates blood flow in major veins, arteries, and the
cerebrovascular system?
Give this one a try later!
Doppler ultrasonography
Which type of diagnostic imaging is designed to show motion in joints through x-ray
imaging?
computed tomography
fluoroscopy
myelography
venography
, Give this one a try later!
fluoroscopy
Fluoroscopy permits objects placed between a fluorescent screen and a
roentgen tube to become visible. A continuous x-ray beam is passed
through the body part being examined. The beam is transmitted to a
monitor so that the body part and its motion can be seen in detail.
(T/F) Bone scans produce cross sectional images based on x ray attenuation
Give this one a try later!
False
- computed tomography
Which medical imaging technique would best detect an intracranial bleed such as a
stroke?
computed tomography scan
functional magnetic resonance imaging
positron emission tomography
magnetic resonance imaging
Give this one a try later!
computed tomography scan
Computed tomography scans (CT scans) combine multiple x-rays with
computer imaging to examine soft tissues of the body. A CT scan can
accurately detect areas of bleeding based on absorption rates of x-rays.
