HESI DIAGNOSTIC IMAGING EXAM
2024-2025
What is the metallic element that causes radiograph film to turn black when
exposed and developed? - ANSWER Silver
What is the purpose of the screen on an X-ray cassette? - ANSWER To reduce the
exposure required to create an image on the film.
The current approved standard image format for digital radiography is known as
DICOM. DICOM files offer numerous advantages over other types of picture files.
Which of the following is not true of DICOM images? - ANSWER DICOM picture
files can be emailed to other vets or owners and viewed in nearly any photo viewer.
Which of the following options best represents the "heel effect" in diagnostic
radiology? - ANSWER X-ray beam intensity decreases towards the anode side of
the x-ray machine.
Many X-ray machines used in veterinary medicine include a two-step exposure
procedure. The first stage is to depress a button or push a pedal halfway to prepare
the machine for the exposure, followed by a second button or full depress of the
pedal to take the exposure. What happens in the X-ray machine once the first phase
is initiated? - ANSWER The anode rotates as the filament is heated.
Which of the following is not part of the axial skeleton? - ANSWER Limbs
Which of the following components or settings influences the quality of the x-ray
beam? - ANSWER KVp and Filtration
, What will an area of the film look like if it does not come into touch with the
developer but does go through the fixer and the remaining processing steps? -
ANSWER It'll be evident.
Which of the following should be avoided when administering barium for an upper
GI radiograph series? - ANSWER Aspiration pneumonia.
You take a series of chest radiographs and find that they all appear darker (more
exposed) on one side of the film. Which of the following is the most plausible
explanation? - ANSWER The X-ray beam is typically more powerful on one side
of the field.
What location is contrast administered into during an arthrogram? ANSWER Joint
All of the following radiation protective techniques are intended to reduce the
technician's dose, EXCEPT which of the following? - ANSWER Filtration is
applied at the X-ray tube portal.
When obtaining a radiograph of the tibia and fibula, what will happen if the x-ray
beam is perpendicular to the tibia and fibula but not to the x-ray cassette and film? -
ANSWER The fibula and tibia will appear elongated.
A cystogram is a radiographic examination used to determine the position, shape,
and lesions affecting what structure? - ANSWER Urinary bladder
Which of the following components of a digital radiography system has the greatest
impact on image quality? - Answer Monitor
Which of the following are the components of a double-contrast cystogram? -
ANSWER Soluble positive contrast media and air are injected directly into the
bladder.
