ARDMS Sonography Principles and Instrumentation Sample Questions (Q44-Q49):

NEW QUESTION # 44
Which component of a contrast agent causes a marked mismatch in impedance between the agent and blood?

  • A. Solid
  • B. Gas
  • C. Viscous liquid
  • D. Serous liquid

Answer: B

Explanation:
Contrast agents used in ultrasound imaging typically consist of microbubbles filled with gas. The significant mismatch in acoustic impedance between the gas in the microbubbles and the surrounding blood creates strong reflectors of the ultrasound waves, enhancing the echogenicity of blood and improving the visibility of blood flow and tissue perfusion. The high contrast provided by the gas-filled microbubbles makes them particularly effective as ultrasound contrast agents.

NEW QUESTION # 45
Which ultrasound adjustment allows for an increased frame rate in color flow Doppler?

  • A. Using multiple focal zones
  • B. Increasing sector scan width
  • C. Decreasing depth
  • D. Using continuous wave Doppler

Answer: C

Explanation:
Frame rate in color flow Doppler is influenced by several factors, including the imaging depth. Decreasing the depth reduces the time it takes for sound waves to travel to the imaging area and back to the transducer. This allows for more frames to be captured per second, thereby increasing the frame rate. Higher frame rates improve temporal resolution, making it easier to visualize moving structures.

NEW QUESTION # 46
Which artifact results from decreased attenuation?

  • A. Reverberation
  • B. Comet tail
  • C. Enhancement
  • D. Ringdown

Answer: C

Explanation:
Enhancement is an artifact that results from decreased attenuation. When an ultrasound wave travels through a medium with lower attenuation compared to surrounding tissues, it loses less energy. Consequently, the structures located deeper than the low-attenuation medium appear brighter on the ultrasound image. This artifact is commonly observed behind fluid-filled structures, such as cysts or the urinary bladder, where the sound waves encounter minimal resistance and thus less attenuation. Reference:

NEW QUESTION # 47
If the speed of sound in a medium is less than the average speed of sound in soft tissue, where will the echo be placed on an image?

  • A. Not visualized
  • B. Too shallow
  • C. Laterally
  • D. Too deep

Answer: D

Explanation:
The placement of an echo on an ultrasound image is dependent on the assumption that the speed of sound in soft tissue is 1540 m/s. If the speed of sound in the medium is less than this assumed speed, the ultrasound system will interpret the returning echo as taking longer to return than it actually does. This causes the system to place the echo deeper in the image than its actual position. Therefore, the echo will be displayed "too deep" in the image.

NEW QUESTION # 48
What is the relationship between overall gain and image brightness?

  • A. The higher the overall gain, the darker the image
  • B. There is no relationship between overall gain and image brightness
  • C. The higher the overall gain, the brighter the image
  • D. The lower the overall gain, the brighter the image

Answer: C

Explanation:
Overall gain in ultrasound refers to the amplification of all the received echo signals. Increasing the overall gain amplifies the signals, making the entire image brighter. Conversely, decreasing the overall gain reduces the signal amplification, resulting in a darker image. Overall gain adjustment affects the entire image uniformly, unlike time gain compensation (TGC), which adjusts the gain at different depths independently.
