1

What are the two types of tissue that can develop into CA?

Ductal
Parenchymal

2

What happens with breast tissue with increasing age? What is the consequence of this for imaging?

Fatty increase, better for imaging

3

What are the five characteristics of imaging for breast tissue?

1. Shape
2. Margin
3. Orientation
4. Echo
5. Posterior features

4

Black hole on a US mean white?

Hypoechoic = more likely to by cystic

5

Lot of whiteness on US signifies what?

Highly dense tissue--more likely to be cancerous

6

What is shadowing in the context of ultrasound?

dense structure interfering with the echo

7

What is isoechoic?

Equally hyper and hypoechoic

8

What are the classical findings of a cyst on US?

Black ball with shadowing posterior to it

9

Fibroadenoma looks like what on US?

Heterogenous circle

10

What are the characteristics of malignancies on US?

big mangled mas of stuff wwo small densities all up in it

11

Spiculation is what and is concerning for what?

Black lines that spew out all over the place
CA

12

What is the gold standard for breast CA prevention?

Mammography

13

What happens to the sensitivity of mammography with extremely dense breast tissue?

Lowers

14

What are the most worrisome findings on a mammography?

Microcalcifications

15

What are the clips used for in breast imaging?

mark the site of biopsy

16

When are microcalcifications particularly concerning?

When grouped together

17

BIRADS score is sued for what?

How likely a pt is to have breast CA based on imaging

18

What is a 0 on the BIRADs scoring?

Presence of a radiological finding requiring further evaluation

19

What is a 1 on the BIRADs scoring?

No radiological finding is observed. The study is normal

20

What is a 2 on the BIRADs scoring?

Normal, but has other features and should f/u later

22

What is a 4 on the BIRADs scoring?

Suspicious lesions that need biopsy

23

What is a 5 on the BIRADs scoring?

Highly suspicious for breast CA. Biopsy again needed

What is a 6 on the BIRADs scoring?

Confirmed breast CA by radiologist and pathologist

25

What is a partial mastectomy?

taking out a portion of the breast tissue

26

What is a sentinel lymph node?

First lymph node that will harbor CA

27

What is the dye used for breast lymph node evaluation?

Technetium

What is a faxitron?

machine used for visualizing breast tissue biopsy
