Artifact - ...(ANSWERS)....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 - ...(ANSWERS)....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 - ...(ANSWERS)....A structure in the body that contains both cystic and
solid components.
Echogenic - ...(ANSWERS)....A structure or medium that produces echoes.
Edge Shadowing - ...(ANSWERS)....Decreased echo amplitude distal to the edge of
a structure. This artifact results from refraction of the sound beam.
Enhancement - ...(ANSWERS)....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 - ...(ANSWERS)....A structure that has an uneven texture
(hypoechoic and hyperechoic echoes throughout). Synonym - non-uniform.
, 2
Homogeneous - ...(ANSWERS)....Smooth uniform texture
Ipsilateral - ...(ANSWERS)....On the same side.
Contrlateral - ...(ANSWERS)....On the opposite side.
Isoechoic - ...(ANSWERS)....Same echogenicity as another structure or the
surrounding tissue.
Noise - ...(ANSWERS)....Spurious echoes throughout the image.
Real-time - ...(ANSWERS)....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 - ...(ANSWERS)....Artifact causing linear echoes parallel to a strong
interface. Sound "bounces"
Ring Down - ...(ANSWERS)....Reverb in which numerous parallel echoes are seen
for a considerable distance. E.g. a biopsy needle.
, 3
Sensitivity - ...(ANSWERS)....The ability to diagnose disease in a patient when
disease is present.
Texture - ...(ANSWERS)....The pattern of echoes seen from a mass or area of
interest in the body.
Refractive Edge Shadowing - ...(ANSWERS)....Bending of a sound beam and loss of
sound energy causing a shadow.
Mid level gray corresponds to _____ in the breast. - ...(ANSWERS)....Fat
Hyperechoic describes what three structures visualized in breast sonography. -
...(ANSWERS)....Fibroglandular tissue, Cooper's Ligament, Skin
What frequency transducer is optimal for breast imaging? - ...(ANSWERS)....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.... - ...(ANSWERS)....Focusing along the short
axis of the transducer.
What design of transducer is used in breast imaging? - ...(ANSWERS)....Linear
array is optimal
, 4
The advantage of a rectangular image over a sector image is the avoidance of
what artifact? - ...(ANSWERS)....Beam divergence
Interventional procedures are more accurately guided with a _______
__________ probe. - ...(ANSWERS)....Linear array
When is a curved array transducer used in breast imaging? -
...(ANSWERS)....Pathology too large to fit on linear image
Most linear transducers in breast sonography are ______ arrays. -
...(ANSWERS)....1-D
1-D arrays offer a fixed focus in the ________ plan (short axis) -
...(ANSWERS)....Elevation
1.5-D matrix array transducers have multiple elements along the _____ axis of the
probe. - ...(ANSWERS)....Short
1.5-D arrays offer some electronic focusing in the __________ plane. -
...(ANSWERS)....Elevation
2-D array transducers are not currently _________. - ...(ANSWERS)....available
