Alternative imaging Flashcards
alternative imaging technologies do you need to take PPE into consideration because it uses ionizing radiology to produce its images
CT
Which imaging modality is superior for demonstrating the brain and spinal cord as well as soft tissue structures
MRI
For which of the following imaging modalities do patients need to be anesthetized for
MRI
This is real time moving images that uses low mA and high kVp
fluoroscopy
fluoroscopy uses a table unit and a __ arm
C
fluoroscopys arm can go from DV to lateral without moving the patient
true
the point of interest in a CT scan is called a
fulcrum
this is responsible for the 3D image in a CT scan
matrix of voxels
every tissue has a __ value of units in CT scans
hounsfield
CT scans can be as thin as ___ MM
1
MRI safety includes no __ objects
metal
MRIs are powerful __ fields
magnetic
unit of strength for magents in MRIs
tesla
the contrast media we use in MRIs. it alters T1 properties of tissues so the tissue lights up
gladolinium
the time for half of radioactive atoms to decay into stable forms is called
half life
the quantity identifier for radiation for radiation emitted from nuclear medicine is a __
curie
used to treat hyperthyroidism in cats
I 131
technetium-99 is used for bone scars in which species
equine
This procedure can be used with ultrasonography. Fluorodeoxyglucose is most commonly used as it attaches to compounds such as water, glucose and ammonia so that we can see images of the biochemistry and function instead of anatomy and structure of brains and hearts.
PET
equines need to have boots on their feet, remain in isolation stalls and have legs wrapped to avoid contamination
true
how long do you need to wait to clean up radioactive waste spills
72 hours
the term for introduction of air when using an endoscope
insufflation
Videoscopes have a chip in the distal tip and transmit images via a processor to a video monitor. While they offer better image quality, they are quite expensive
true
this scope is used in nasal cavities, joints and bladders
rigid endoscope
endoscopes should be cleaned with
enzymatic cleaners
