ARDMS BREAST REGISTRY REVIEW EXAM
| CERTIFIED Q&A
Artifact - correct-answer-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 - correct-answer-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 - correct-answer-A structure in the body that contains both cystic and
solid components.
Echogenic - correct-answer-A structure or medium that produces echoes.
Edge Shadowing - correct-answer-Decreased echo amplitude distal to the edge of
a structure. This artifact results from refraction of the sound beam.
,2|Page
Enhancement - correct-answer-Increased echo amplitude returning from regions
lying beyond an object that causes little or no attenuation of the sound beam
(typically a cystic structure). This artifact results in a brighter than normal
appearance.
Heterogeneous - correct-answer-A structure that has an uneven texture
(hypoechoic and hyperechoic echoes throughout). Synonym - non-uniform.
Homogeneous - correct-answer-Smooth uniform texture
Ipsilateral - correct-answer-On the same side.
Contrlateral - correct-answer-On the opposite side.
Isoechoic - correct-answer-Same echogenicity as another structure or the
surrounding tissue.
,3|Page
Noise - correct-answer-Spurious echoes throughout the image.
Real-time - correct-answer-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 - correct-answer-Artifact causing linear echoes parallel to a strong
interface. Sound "bounces"
Ring Down - correct-answer-Reverb in which numerous parallel echoes are seen
for a considerable distance. E.g. a biopsy needle.
Sensitivity - correct-answer-The ability to diagnose disease in a patient when
disease is present.
Texture - correct-answer-The pattern of echoes seen from a mass or area of
interest in the body.
, 4|Page
Refractive Edge Shadowing - correct-answer-Bending of a sound beam and loss of
sound energy causing a shadow.
Mid level gray corresponds to _____ in the breast. - correct-answer-Fat
Hyperechoic describes what three structures visualized in breast sonography. -
correct-answer-Fibroglandular tissue, Cooper's Ligament, Skin
What frequency transducer is optimal for breast imaging? - correct-answer-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.... - correct-answer-Focusing along the short
axis of the transducer.
What design of transducer is used in breast imaging? - correct-answer-Linear
array is optimal
