Tissues with lesser density (silicone implants) have lower propagation speeds
causing structures to appear too - ans -Deep
Artifact caused by a difference in propagation speed causing structures to appear
too superficial or deep - ans -Propagation speed error
Optimal transducer frequency for broad-bandwidth breast imaging - ans -10MHz
(or 7.5-13MHz with a 1.5cm fixed elevation plane focus)
Ability of a sono system to distinguish moving structures or dynamics over time -
ans -Temporal resolution
What type of resolution is not affected by scanning superficial structures - ans -
Temporal resolution
Relates to the amplitude of a transmitted voltage and affects the actual intensity
of the beam - ans -Output power
Number of gray shades- measure of magnitude of signals - ans -Dynamic range
Expressed in decibels (dB) - ans -Dynamic range
Ratio of smallest to largest signal that a system can receive, process and display
without disruption - ans -Dynamic range
Examiner can adjust dynamic range (shades of gray) with two settingsb - ans -TGC
and threshold compression settings
,A low amplitude signal is shown as - ans -Black
A high amplitude signal is shown as - ans -White
When a patient hums with power Doppler to distinguish a mass from normal
tissue - ans -Fremitus
A standoff pad must not exceed this size in order to not affect the fixed elevation
plane focus - ans -1cm
Type of probe that sonographer cannot vary focus - ans -Mechanical sector
Three settings that affect amplitude - ans -Power, overall gain, TGC
Applies voltage - ans -Power
Affects the brightness of echoes - ans -Overall gain
Affects brightness of echoes at different depths - ans -TGC
Frequency causing less penetration and better resolution - ans -High
Frequency causing more penetration and decreased resolution - ans -Low
123 of the ABC-123 method indicates - ans -Distance from nipple
ABC of 123-ABC method indicates - ans -Depth
Position best for scanning medial breast due to flattening medial breast and
continuity with chest wall - ans -Supine
Technique for scanning the main breast duct and nipple in which the nipple is
rolled over the index finger - ans -Two-handed technique
, Probe allowing for imaging perpendicular to chest wall, good near field imaging,
reliable measurements due to less beam divergence, and frequency and focus
options - ans -10MHz linear array
Affected by changing the number of focal zones, depth and size of image - ans -
Frame rate
Mammo marker is placed in the region toward the - ans -Axilla
Spectrum of frequencies - ans -Bandwidth
Relationship between frequency and axial resolution - ans -Direct
Relationship between frequency and lateral resolution - ans -Direct
Relationship between frequency and penetration - ans -Inverse
Relationship between depth and frame rate - ans -Inverse
Doppler aiding visualization of small tortuous vessels - ans -Power Doppler
Doppler that sensitive to low flow, not angle dependent and gives no information
on direction of flow - ans -Power Doppler
Breast tissue exhibiting medium level gray - ans -Fat
Three breast layers - ans -Subcutaneous, mammary, retromammary
Breast layer containing skin and fat - ans -Subcutaneous
Breast layer with parenchymal tissue - ans -Mammary
Breast layer with a thin layer of fat and connective tissue separating mammary
from pec muscle - ans -Retromammary
Scanning depth is adequate when visualizing - ans -Skin to pec muscle
