ARDMS Sonography Principles and Instrumentation Sample Questions (Q126-Q131):

NEW QUESTION # 126
What is the function of M-mode?

A. Measure movement
B. Create 3D images
C. Monitor blood flow
D. Visualize internal organs

Answer: A

Explanation:
* M-mode (Motion mode) is used in ultrasound to measure and display the movement of structures over time.
* This mode is particularly useful in cardiac imaging to assess the motion of heart walls and valves.
* M-mode provides a one-dimensional view of the motion of tissues and is often used in conjunction with
2D imaging for a comprehensive assessment.
* It is essential in evaluating the dynamic function of organs, especially in cardiology, where precise measurements of cardiac structures' movement are crucial.References:
* ARDMS Sonography Principles and Instrumentation guidelines on modes of ultrasound imaging and their clinical applications.

NEW QUESTION # 127
Which ultrasound adjustment allows for an increased frame rate in color flow Doppler?

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

Answer: B

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 # 128
Which artifact may be caused by incorrect color Dopplergain setting?

A. Twinkle
B. Aliasing
C. Clutter/Haze
D. Bleed/Blossoming

Answer: D

Explanation:
Incorrect color Doppler gain settings can cause the artifact known as bleed or blossoming. When the color Doppler gain is set too high, it can cause the color signal to "bleed" outside the actual boundaries of the blood vessel, leading to an overestimation of the area of flow. This artifact makes it appear as though the blood flow extends beyond the true vessel walls, which can obscure the accurate interpretation of the Doppler image.

NEW QUESTION # 129
In this image, which artifact is demonstrated?
A close-up of a sound wave Description automatically generated

A. Spectral broadening
B. Mirroring
C. Aliasing
D. Range ambiguity

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The provided image shows a pulsed-wave Doppler spectral display. There are two identical Doppler spectra present - one on the top and an inverted one on the bottom - a classic appearance of the mirroring artifact.
Mirroring occurs when the strong Doppler signal reflects off a highly reflective interface and produces a duplicate signal on the opposite side of the baseline. The mirrored signal mimics the original spectral waveform but appears as a reversed, symmetric version.
According to official sonography Principles and Instrumentation references:
"Mirror image artifact in Doppler (also called cross-talk) occurs when a strong signal is incorrectly displayed on both sides of the baseline, producing a duplicated waveform."
* Aliasing would show wrap-around of velocities beyond the Nyquist limit, typically producing a cutoff and color reversal - not seen here.
* Range ambiguity produces overlapping signals from different depths - also not applicable here.
* Spectral broadening would result in widening of the Doppler spectral trace - which is not evident here.
Therefore, the correct answer is A: Mirroring.

NEW QUESTION # 130
Which change was made after acquiring image A to produce image B?

A. Decreased pulse repetition frequency
B. Increased spectral gain
C. Increased sweep speed
D. Decreased wall filter

Answer: A

Explanation:
Increased Sweep Speed: This affects the display of the waveform over time but does not impact the appearance of the spectral Doppler signal in the way shown.
Decreased Pulse Repetition Frequency (PRF): Lowering the PRF can lead to aliasing, which is evident as the waveform wrapping around in the spectral display from image A to image B. This makes the velocity appear higher than it actually is.
Decreased Wall Filter: This adjustment primarily affects the elimination of low-frequency Doppler signals but does not typically cause the kind of changes seen in the images.
Increased Spectral Gain: Increasing the gain would result in a brighter spectral display but not the wrapping of the signal as seen.
