ARRT BREAST SONOGRAPHY EXAMCOMPLETE ANSWERS 100% CORRECT (LATEST )
1. Which method of patient positioning is best for evaluating the medialaspect of the breast?:
Supine
1. The two-handed technique is used to image:: The main breast duct andnipple
Two hands are required as the nipple is rolled over the sonographer's index finger of one hand
while using the other hand to scan along the long axis of the main ductthrough the nipple
2. Which of the following transducers would be the best choice for breastimaging:: 10 MHz
Linear array transducers allow for imaging perpendicular to the chest wall and provide a large
rectangular field of view, including good visualization in the near field. They are easier to keep
in direct contact with the skin, and measurements arereliable because there is no beam
divergence along the edges. Linear array transducers offer variable frequency options and
narrow and variable focus selections
3. Selecting multiple focal zones will:: Decrease frame rate
Frame rate can be affected by changing the number of focal zones, depth of image,and image
size.
4. When viewing a mammogram, one always sees the marker in the regiontoward the::
Axilla
5. If a breast sonographic image is labeled, Rt. AR 2:00 1A, the area described is:: Antiradial
scan of the right breast, upper inner quadrant near the nipple, underthe skin
6. When viewing a mammogram, a mass is marked near the CC marker in the right breast.
This will indicate to the sonographer that the mass is located:: Inthe LATERAL breast
The mammographic marker CC ( craniocaudal) is always placed near the axilla, which is
lateral to the breast; therefore, the mass would be located more toward thelateral aspect of the
breast
7. A transducer that can operate multiple frequencies is said to have:: Broadbandwidth
Bandwidth refers to the spectrum of frequencies (high and low) emitted by atransducer
8. All of the following statements about high-frequency transducers are trueEXCEPT::
Sound travels fast
, For practical purposes, we assume that sound travels through soft tissues at theaverage speed
of 1540 m/sec
9. Decreasing depth will: Increase frame rate
Frame rate can be affected by changing the number of focal zones, depth of range,and image
size
10. Increasing the overall gain control will:: Cause artifactual echoes
Increasing the overall gain affects the entire image and causes vessels and ductsto fill in with
the echoes
11. Which of the following allows for better demonstration of small, tortuousvessels?: Power
Doppler
Power-Doppler is less angle-dependent and more sensitive to low-flow states. It re- lies on the
number of moving red blood cells more than their velocity. It demonstrates perfusion but provides
no information related to direction of flow.
12. Which of the following affect(s) the frame rate?: Number of focal zones andSize of image
Frame rate can be affected by changing the number of focal zones, depth of image,and image
size
13. Ideally, the elevational focus for breast imaging should be fixed at:: 1.5 cm
14. An increase in the intensity of echoes beneath a structure is called:: Enhancement
15. Of the following, which would NOT be a good indication for performing abreast
sonogram?: Evaluate a mass for microcalcifications
16. When setting the TGC (Time gain compensation) control for breast imaging, what tissue
should be a medium level of gray?: Fat
All breast tissues are compared to fat since fat should exhibit a mid level shade of gray on
sonography
17. The lactiferous ducts are best seen when scanning: Radial
Lactiferous ducts converge toward the nipple into a main duct. Radial scanningallows for
imaging these duct branches in the long axis.
