Indications for Screening Ultrasound

Next, I would like to talk about,

0:03

Indications for Screening Ultrasound.

0:05

And these are the indications according to the Society of Breast Imaging.

0:10

Indications include average-risk women

0:13

with dense breasts as an adjunct to mammography.

0:16

Screening ultrasound should never be performed in isolation,

0:20

or high-risk women for who qualify for MRI screening but cannot have an MRI.

0:27

So somebody with a pacemaker, for example,

0:29

somebody with an allergy to gadolinium, or other reasons,

0:33

some kind of metal foreign body inside of their body

0:36

that they cannot have MRI.

0:38

Screening Breast Ultrasound.

0:40

The sensitivity of mammography and dense breasts ranges from about 47.8% to 64.4%

0:47

In non dense breasts, the sensitivity is upwards of 85%

0:51

Patients with dense breasts have

0:53

an increased risk of developing breast cancer.

0:55

Thus, we need a better way to screen them.

0:57

Screening Breast Ultrasound has been shown

0:59

to detect an additional three to four cancers per thousand women screened.

1:04

So there are two ways to perform Screening Breast Ultrasound.

1:07

It can be performed with Handheld

1:09

Screening Breast Ultrasound versus ABUS, Automated Breast Ultrasound.

1:14

Handheld Ultrasound is operator dependent

1:17

and time-consuming, and it also requires extensive training.

1:21

This is an image from a Handheld Screening Breast Ultrasound that found a cancer.

1:25

Automated Breast Ultrasound is standardized, reproducible

1:30

and operator independent.

1:32

It's quick, however, the downside is it's prone to artifacts.

1:36

But on a plus side,

1:37

you get to see the breast in multiple planes and it requires less training.

1:42

Both have equivalent rates of breast cancer detection.

1:45

Over here is an example of what an ABUS looks like,

1:48

and we can see this black defect in the tissue here.

1:51

And when you go to the orthogonal view on ultrasound,

1:55

you can see there's a regular mask that looks very similar to a handheld version.

1:59

And that is all for indications for screening breast ultrasound.
