16
Q

When do you increase the transducer pressure when scanning the breast? (2)

A
  1. Greater penetration

2. Scanning the subareolar region

17
Q

What are 4 techniques when scanning the breast?

A
  1. Maximize tissue thinness
  2. Reduce reflective and refractive attenuation
  3. Maintain ultrasound transducer parallel to breast surface
  4. Maintain ultrasound beam perpendicular to breast tissue
18
Q

What can a shadow be caused by the breast?

A

The erection of the nipple

19
Q

How can you decrease the shadow caused by the nipple? (3)

A
  1. Apply more pressure
  2. Use more gel
  3. Scan the nipple area obliquely
20
Q

What is the benefit for scanning the nipple region obliquely? (3)

A
  1. Reduces the shadowing
  2. Avoids the need for a standoff pad
  3. Provides adequate visualization of the anatomy posterior to the nipple
21
Q

Palpable nodule

A

Is a pea or bee-bee sized, then it is very small and near the skin

22
Q

Whats the best way to visualize a palpable nodule?

A

Use a 1 cm standoff pad or a large “glop” of gel in order to move the elevation plane focus closer to the skin

23
Q

What is the most common scanning technique for the breast?

A

Initially scan using the grid scanning pattern, followed by a radial (clock face) technique for the hard copy imaging

24
Q

How do you scan the breast in a grid pattern? (4)

A
  1. Begin in the upper outer quadrant, scanning in transverse
    - slide inferiorly from top to bottom
  2. Move across and repeat the sweep inferior to superior
  3. Repeat this across the breast
  4. Rotate into a sagittal plane and repeat the pattern
25
Q

What is the number one modality for examining the breast?

A

Mammogram

- US helps confirm it

26
Q

When do you use US instead of mammography? (4)

A
  1. Below age 40
  2. Pregnant or lactating
  3. Someone who is young
  4. Males
27
Q

How does cartilage appear on US?

A

More hypoechoic

28
Q

How does bone appear on US?

A

More echoic

29
Q

What kind of vascularity should there be in a lactating breast?

A

None

30
Q

How is the breast scan described as?

A

A clock face

- begin at 12 o’clock in a sagittal plane with the toe of the probe at the nipple
