2025 ACTUAL EXAM 450 QUESTIONS AND CORRECT DETAILED
ANSWERS (VERIFIED ANSWERS) |ALREADY GRADED A+
Artifact
An echo feature present or absent in a sonographic image that does not
correspond to the presence or absence of a real structure. Eg.
enhancement or shadowing.
Attenuation
The reduction of intensity (and amplitude) of a sound wave as it travels
through a material. Attenuation is due to absorption, reflection, and
scattering.
Complex
A structure in the body that contains both cystic and solid components.
Echogenic
A structure or medium that produces echoes.
Edge Shadowing
Decreased echo amplitude distal to the edge of a structure. This artifact
results from refraction of the sound beam.
Enhancement
Increased echo amplitude returning from regions lying beyond an
object that causes little or no attenuation of the sound beam (typically a
,2
cystic structure). This artifact results in a brighter than normal
appearance.
Heterogeneous
A structure that has an uneven texture (hypoechoic and hyperechoic
echoes throughout). Synonym - non-uniform.
Homogeneous
Smooth uniform texture
Ipsilateral
On the same side.
Contrlateral
On the opposite side.
Isoechoic
Same echogenicity as another structure or the surrounding tissue.
Noise
Spurious echoes throughout the image.
Real-time
The scanning and display of sonographic images at a sufficiently rapid
rate so that moving structures can be seen to move at their natural rate.
***Frame rates of 15 frames per second or greater are considered real
time***
Reverberation
Artifact causing linear echoes parallel to a strong interface. Sound
"bounces"
,3
Ring Down
Reverb in which numerous parallel echoes are seen for a considerable
distance. E.g. a biopsy needle.
Sensitivity
The ability to diagnose disease in a patient when disease is present.
Texture
The pattern of echoes seen from a mass or area of interest in the body.
Refractive Edge Shadowing
Bending of a sound beam and loss of sound energy causing a shadow.
Mid level gray corresponds to _____ in the breast.
Fat
Hyperechoic
describes what three structures visualized in breast
sonography.Fibroglandular tissue, Cooper's Ligament, Skin
What frequency transducer is optimal for breast imaging?
7.0-15.0 MHz is optimal for superior axial and lateral resolution while
maintaining penetration to the chest wall. It should also be
BROADBAND.
Fixed elevation focusing represents....
Focusing along the short axis of the transducer.
What design of transducer is used in breast imaging?
, 4
Linear array is optimal
The advantage of a rectangular image over a sector image is the
avoidance of what artifact?
Beam divergence
Interventional procedures are more accurately guided with a _______
__________ probe.
Linear array
When is a curved array transducer used in breast imaging?
Pathology too large to fit on linear image
Most linear transducers in breast sonography are ______ arrays.
1-D
1-D arrays offer a fixed focus in the ________ plan (short axis)
Elevation
1.5-D matrix array transducers have multiple elements along the _____
axis of the probe.
Short
1.5-D arrays offer some electronic focusing in the __________ plane.
Elevation
2-D array transducers are not currently _________.
available
Imaging depth should penetrate the chest wall-- ___ to ___ cm should
be adequate
