VTNE Domain 6: Diagnostic Imaging Welcome to your VTNE Domain 6: Diagnostic Imaging 1. VTNE: Diagnostic Imaging What is the primary advantage of using a grid in radiographic imaging for veterinary practices? A. Reduces exposure time B. Increases the contrast of the image by absorbing scatter radiation C. Enhances the resolution by increasing the distance between the subject and the detector D. Decreases the amount of radiation needed to produce the image None 2. VTNE: Diagnostic Imaging In veterinary radiography, when adjusting the kVp (kilovoltage peak) settings, how does this influence the contrast of the radiographic image? A. Higher kVp increases the contrast B. Lower kVp increases the contrast C. Higher kVp decreases the contrast D. kVp adjustments have no effect on image contrast None 3. VTNE: Diagnostic Imaging For optimal radiographic quality, the focal-spot size of the X-ray tube should be: A. As large as possible to cover more area B. Small for high-detail imaging C. Large for imaging thick body parts D. Varied based on the distance between the subject and the film None 4. VTNE: Diagnostic Imaging The anode heel effect influences the radiographic image by: A. Increasing radiation intensity on the cathode side B. Decreasing radiation intensity uniformly across the image C. Increasing radiation intensity on the anode side D. Having no significant impact on radiation intensity None 5. VTNE: Diagnostic Imaging When utilizing digital radiography (DR) in veterinary medicine, the main reason for applying a higher signal-to-noise ratio (SNR) is to: A. Increase the speed of image acquisition B. Decrease the exposure time for the patient C. Improve the image quality by enhancing detail visibility D. Reduce the size of the digital file for storage None 6. VTNE: Diagnostic Imaging In veterinary radiography, the term "caliper" refers to a tool used for: A. Measuring the thickness of the patient to set the correct exposure parameters B. Cutting radiographic film to the appropriate size C. Adjusting the focus of the X-ray beam D. Calibrating the radiographic machine annually None 7. VTNE: Diagnostic Imaging What is the significance of the inverse square law in veterinary radiography? A. It states that radiation exposure decreases proportionally with the square of the distance from the source B. It indicates that radiation exposure increases linearly with the distance from the source C. It suggests that the intensity of radiation is inversely proportional to the exposure time D. It describes the relationship between focal spot size and image sharpness None 8. VTNE: Diagnostic Imaging In veterinary radiography, a "grid cut-off" refers to: A. The intentional reduction of exposure parameters to reduce patient dose B. A decrease in image contrast due to improper grid alignment C. The enhanced visibility of grid lines on the final image D. An increase in radiation dose to overcome grid absorption None 9. VTNE: Diagnostic Imaging When considering the use of contrast media in veterinary radiography, which of the following is true regarding iodinated contrast agents? A. They are primarily used for enhancing magnetic resonance images B. They decrease the opacity of tissues to X-rays C. They are contraindicated in patients with renal insufficiency D. They have no impact on allergic reactions in patients None 10. VTNE: Diagnostic Imaging The principle of ALARA in veterinary radiology stands for: A. Always Look At Radiographs Again B. As Low As Reasonably Achievable, referring to radiation exposure C. Automatic Level Adjustment for Radiographic Analysis D. Assess, Learn, Apply, Repeat for radiographic techniques None 1 out of 10 Time is Up! Time's up
