Imaging VTNE UPDATED Exam
Questions and CORRECT Answers
All hard copies of radiographs, computed tomography (CT) scans, ultrasound images, and
magnetic resonance imaging (MRI) studies are: - CORRECT ANSWER- the hospital's
property and part of the patient's record
For a radiograph to be considered admissible as evidence in a court of law, at least the _____
must be permanently imprinted onto it prior to developing. - CORRECT ANSWER- Patient
name or identification number, owner name, hospital name, and date of the examination
The term radiographic technique generally refers to: - CORRECT ANSWER- The machine's
exposure settings (e.g., kVP, mAs) during a given examination
X-rays cannot penetrate: - CORRECT ANSWER- Lead
Concerning the filaments in the x-ray tube that produce electrons, which statement is most
accurate? - CORRECT ANSWER- The small filament may melt more rapidly than the large
filament if an excess load is placed on it.
Why are rotating-anode x-ray machines more powerful than stationary-cathode x-ray
machines? - CORRECT ANSWER- - The former allow greater dissipation of heat.
- The former allow the use of a smaller focal spot with higher tube currents.
- The former allow the use of shorter exposure times.
(all answers are correct)
The primary source of radiation exposure to the technician during radiography is scattered
radiation, which can best be defined as: - CORRECT ANSWER- Lower-energy x-ray
photons that have undergone a change in direction after interacting with structures in the
patient's body
The acronym kVP stands for _____ and controls the _____ of x-ray photons produced. -
CORRECT ANSWER- Kilovolt peak; speed
, You have just taken a thoracic radiograph at 50 kVP and 100 mA at 1/10 second. The pet's
breathing caused his chest to move during the exposure, resulting in a blurry image. On the
retake, how can you correct for this motion to create a clear image of the same density? -
CORRECT ANSWER- Reduce the time to 1/20 second and increase the mA to 200.
You have radiographed a fractured femur in a large dog. The resulting image is too gray; that
is, you can see many shades of gray and a lot of detail in the muscle layers, but the bone is
also too gray, and bony fragments are difficult to see. How can you best correct your settings
to create a clearer image of the fractured bone? - CORRECT ANSWER- Decrease the kVP.
Which statement is most accurate concerning the effects of a change in focus-film distance
(FFD) when taking radiographs? - CORRECT ANSWER- The mAs setting must be changed
according to a standard mathematical formula.
How does one obtain the correct machine settings when taking a radiograph? - CORRECT
ANSWER- Settings are obtained from a "technique chart" created, by trial and error,
specifically for the machine one is using.
Concerning the use of film holders (cassettes) in veterinary radiography, which statement is
most accurate? - CORRECT ANSWER- A "nonscreen" cassette is made of nonrigid
cardboard or plastic and The most commonly used cassettes in companion-animal practice
are rigid and contain an image-intensifying screen.
Care of image-intensifying screens involves: - CORRECT ANSWER- Cleaning them with a
special solution or 70% isopropyl alcohol at least once monthly or whenever screen artifacts
are seen on a radiograph
The purpose of a grid is to: - CORRECT ANSWER- Allow only the primary x-ray beam to
pass through and prevent scattered radiation from reaching the film and Increase the
resolution of thicker body parts.
Most mistakes made in veterinary radiography are related to: - CORRECT ANSWER-
Improper processing techniques
Which statement concerning hand processing versus automatic-film processing of
radiographs is most accurate? - CORRECT ANSWER- Both techniques require the use of
fresh solutions and a well-ventilated darkroom.
