ARDMS BREAST REGISTRY EXAM
REVIEW QUESTIONS AND ANSWERS
Edge Shadowing - ANSWER -Decreased echo amplitude distal to the

edge of a structure. This artifact results from refraction of the sound

beam.



Enhancement - 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 - ANSWER -A structure that has an uneven texture

(hypoechoic and hyperechoic echoes throughout). Synonym -

nonuniform.



Homogeneous - ANSWER -Smooth uniform texture

Ipsilateral - ANSWER -On the same side.



Contrlateral - ANSWER -On the opposite side.

,Isoechoic - ANSWER -Same echogenicity as another structure or the

surrounding tissue.



Noise - ANSWER -Spurious echoes throughout the image.



Real-time - 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 - ANSWER -Artifact causing linear echoes parallel to a

strong interface. Sound "bounces"



Ring Down - ANSWER -Reverb in which numerous parallel echoes are

seen for a considerable distance. E.g. a biopsy needle.


Sensitivity - ANSWER -The ability to diagnose disease in a patient

when disease is present.

,Texture - ANSWER -The pattern of echoes seen from a mass or area

of interest in the body.



Refractive Edge Shadowing - ANSWER -Bending of a sound beam and

loss of sound energy causing a shadow.



Mid level gray corresponds to _____ in the breast. - ANSWER -Fat



Hyperechoic describes what three structures visualized in breast

sonography. - ANSWER -Fibroglandular tissue, Cooper's Ligament,

Skin



What frequency transducer is optimal for breast imaging? - 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.... - ANSWER -Focusing along the

short axis of the transducer.



What design of transducer is used in breast imaging? - ANSWER -

, Linear array is optimal



The advantage of a rectangular image over a sector image is the

avoidance of what artifact? - ANSWER -Beam divergence



Interventional procedures are more accurately guided with a _______

__________ probe. - ANSWER -Linear array



When is a curved array transducer used in breast imaging? -

ANSWER -Pathology too large to fit on linear image



Most linear transducers in breast sonography are ______ arrays. -

ANSWER -1-D



1-D arrays offer a fixed focus in the ________ plan (short axis) -

ANSWER -Elevation

1.5-D matrix array transducers have multiple elements along the

_____ axis of the probe. - ANSWER -Short



1.5-D arrays offer some electronic focusing in the __________ plane. -
