Topic 3 : Imaging Routines Flashcards
What is fluoroscopy?
Fluoroscopy is a study of moving body structures–similar to an X-ray “movie.” A continuous X-ray beam is passed through the body part being examined. The beam is transmitted to a TV-like monitor so that the body part and its motion can be seen in detail.
What are the two forms of digital radiography
Computed radiography (CR) Direct digital radiography (DR)
What does MRI stand for
Magnetic resonance imaging (MRI)
What does NMRI stand for
nuclear magnetic resonance imaging
What does MRT stand for
magnetic resonance tomography
What is an MRI (Magnetic resonance imaging)
is a medical imaging technique used in radiology to investigate the anatomy and function of the body in both health and disease. MRI scanners use strong magnetic fields and radiowaves to form images of the body. The technique is widely used in hospitals for medical diagnosis, staging of disease and for follow-up without exposure to ionizing radiation.
What is scintigraphy?
a technique in which a scintillation counter or similar detector is used with a radioactive tracer to obtain an image of a bodily organ or a record of its functioning
What is scintingraphy used for?
used as a diagnostic tool mainly in equine (bone) work, but can also be used as diagnostic in small animals for studies in thyroid, renal, portal -liver, bone and checking glomerular filtration rate
What does CT stand for?
Computed Tomography
What does CAT stand for?
Computed Axial Tomography
What is a CT scan?
special X-ray tests that produce cross-sectional images of the body using X-rays and a computer. CT scans are also referred to as computerized axial tomography.
What does PET scan stand for
Positron emission tomography–computed tomography
What is a pet scan?
a medical imaging technique using a device which combines in a single gantry system both a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, so that images acquired from both devices can be taken sequentially, in the same session, and combined into a single superposed (co-registered) image
What are PET scans used to diagnose
A PET scan allows physicians to measure the body’s abnormal molecular cell activity to detect:
Cancers:
To assess tumor aggressiveness
To monitor success of therapy
To detect early any recurrent tumors
To provide a whole-body survey for cancer that may have spread
To identify benign and malignant growths
To help doctors decide on the most appropriate cancer treatment
Brain Disorders
Heart disease
What is a CT scan used to diagnose?
. This allows veterinarians to visualise organs, bones and blood vessels and diagnose health conditions such as cancer, trauma, injuries and abnormalities in the head and abdomen.
