Breast Ultrasound Examination

Question 1

Elevated ipsilateral shoulder is the same position as ________ _________ __________

Answer 1

Contra lateral posterior oblique

Question 2

What is the advantage is positioning the patient in the contralateral posterior oblique position

Answer 2

1. Minimizes breast thickness so that tissues can be penetrated with a higher frequency transducer with better focusing
2. Flattens breast tissue so that transducer is parallel with skin, reducing angle shadowing.

Question 3

How is the patient positioned for examination of a medial lesion

Answer 3

Supine with ipsilateral arm raised

Question 4

Why would a patient be positioned upright

Answer 4

To allow better correlation with mammographic findings

Question 5

The _______ and ________ settings should be adjusted so that the echogenicity of _________ is a medium gray shade

Answer 5

Gain, dynamic range, fat

Question 6

Term for echogenicity that is less echogenicity than fat

Answer 6

Hypoechoic

Question 7

Term for echogenicity that has similar echogenicity to fat

Answer 7

Isoechoic

Question 8

Term for echogenicity that is more echogenic than fat

Answer 8

Hyperechoic

Question 9

Term for echogenicity that is echo free

Answer 9

Anechoic

Question 10

How is the patient positioned for a breast ultrasound?

Answer 10

Supine

Contralateral posterior oblique

Question 11

The radial scan plane is best used for evaluating ______

Answer 11

Lactiferous ducts

Question 12

What is echo palpitation

Answer 12

Immobilizing a mass between fingers and scanning over the mass

Question 13

How does the acoustic standoff pad improve imaging

Answer 13

1. Optimizes near field focusing

2. Reduces slice thickness artifacts

Question 14

Thickness of the standoff pad should not exceed ______ for transducers with an elevation focus of 1.5 cm

Answer 14

1.0 cm

Question 15

When using a standoff pad, which artifact is commonly seen

Answer 15

Reverberation

Question 16

How is compression useful

Answer 16

1. Decrease tissue thickness for better sound penetration
2. Reduced shadowing from Cooper’s ligaments by placing tissues more // to skin
3. Reduces shadowing beneath scar
4. Assesses:
   a) compressibility
   b) lesion mobility
   c) movement of internal echoes

Question 17

Drawbacks of compression

Answer 17

1. Reduction in Doppler flow
2. Poor margin of adjacent tissues presses against mass
3. Poor visualizing of superficial lesions due to near field artifacts and poor focusing

Question 18

How does fremitus work

Answer 18

Chest vibration creates a Doppler signal except in the are of mass

Question 19

Benefit of fremitus

Answer 19

1. Visualize borders
2. Fat lobule vs solid mass
3. Artifact shadowing vs true shadowing

Question 20

ACR requires that mass dimensions be documented in ______ planes and in _______dimensions

Answer 20

2, 3

Question 21

What does BI-RADS stand for

Answer 21

Breast Imaging Reporting and Data System

Question 22

Increased echogenisity is the same as

Answer 22

Hyperechoic

Question 23

Lipomas appear __________ with a hyperechoic pattern within

Answer 23

Isoechoic
