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
The advantage of a rectangular image over a sector image is the avoidance of
what artifact? - CORRECT ANSWER ✔✔- Beam divergence
Interventional procedures are more accurately guided with a _______
__________ probe. - CORRECT ANSWER ✔✔- Linear array

,When is a curved array transducer used in breast imaging? - CORRECT ANSWER
✔✔- Pathology too large to fit on linear image
Most linear transducers in breast sonography are ______ arrays. - CORRECT
ANSWER ✔✔- 1-D
1-D arrays offer a fixed focus in the ________ plan (short axis) - CORRECT
ANSWER ✔✔- Elevation
1.5-D matrix array transducers have multiple elements along the _____ axis of the
probe. - CORRECT ANSWER ✔✔- Short
1.5-D arrays offer some electronic focusing in the __________ plane. - CORRECT
ANSWER ✔✔- Elevation
2-D array transducers are not currently _________. - CORRECT ANSWER ✔✔-
available
Imaging depth should penetrate the chest wall-- ___ to ___ cm should be
adequate - CORRECT ANSWER ✔✔- 3, 6
An echo's brightness is controlled by ______ - CORRECT ANSWER ✔✔- gain
Know overall gain, TGC, and output power - CORRECT ANSWER ✔✔- This is
ultrasound elementary.

,If your image is too bright decrease the ______________. - CORRECT ANSWER
✔✔- Output power
If your image is too dark increase the ____________. - CORRECT ANSWER ✔✔-
Receiver gain
__________ focal zones are recommended for breast imaging. - CORRECT
ANSWER ✔✔- Multiple
Multiple focal zones will decrease what? - CORRECT ANSWER ✔✔- Frame rate
a 7-12 MHz probe must be used to obtain an elevation focus depth of ____ to
_____ cm. - CORRECT ANSWER ✔✔- 1,2
10 MHz = _____ cm elevation plane focus - CORRECT ANSWER ✔✔- 1.5
____________ (artifact) decreases contrast resolution and spatial resoution (both
axial and lateral). Places unwanted echoes in cysts. - CORRECT ANSWER ✔✔-
Volume averaging
_______ __________ is more sensitive to low velocity flow and offers angle
independence. - CORRECT ANSWER ✔✔- Power Doppler
Three reasons Doppler is useful: - CORRECT ANSWER ✔✔- (1)Solid vs Cystic
(2)Inflammed vs Non-Inflammed
(3)Complicated Cyst vs Complex Cyst vs Intraductal Papilloma
3|Page
, To optimize Doppler for breast imaging (4 things) - CORRECT ANSWER ✔✔- (1)
Low velocity scale
(2) Low filter setting
(3) Optimal Doppler gain setting
(4) Increased PRF for high velocities
Uses compounding technique to combine ultrsound lines acquired from different
scanning directions (angles). Improves tissue differentiation, margin visualization,
and internal architecture creating a "smoother" more realistic image. - CORRECT
ANSWER ✔✔- Spatial compounding
What are the advantages (2) and disadvantages (2) of spatial compounding? -
CORRECT ANSWER ✔✔- Advantages:
-Clears cysts
-Reduces speckle and other noise artifacts (clutter)
Disadvantages
-Reduces acoustic enhancement and shadowing artifact
-Subject to blurring
A diagnostic methof that evaluates the elastic properties of tissue. Breast tissues
vibrate differently based on their firmness. - CORRECT ANSWER ✔✔- Elastography
Breast elastography may have the potential to differentiate benign from
malignant breast tumors (BIRADS 3 from BIRADS 4 lesions) and potential reduce
the number of __________. - CORRECT ANSWER ✔✔- Biopsies
