Hello, my name is Olena Weaver.

0:02

I am an associate professor of Diagnostic Radiology

0:06

at MD Anderson Cancer Center in Houston, Texas.

0:09

And I'm, uh, the breast imaging director of

0:12

contrast-enhanced mammography at my institution.

0:15

I am happy and delighted to be a part

0:18

of this, uh, course on contrast-enhanced

0:21

mammography. And contrast-enhanced mammography,

0:24

I believe, is a very valuable tool in breast imaging.

0:28

Uh, it's an emerging tool but already has,

0:31

uh, a lot of very valuable applications.

0:35

It's still being researched, but I think

0:36

the future of this modality is very bright.

0:40

It'll find its way and its role in our everyday,

0:44

uh, life and everyday breast imaging practice.

0:48

I'm glad to be, uh, working,

0:50

uh, with Dr. Jordana Phillips.

0:53

This course will be a part of this, uh,

0:55

overall contrast-enhanced mammography course,

0:58

and I'll present you a case-based review.

1:02

So, uh, I have no disclosures.

1:05

I would like to point out that, uh, the cases

1:08

I will present to you today are going to be

1:11

a little unusual because, uh, the majority of

1:15

the cases I will show you, uh, were done, uh,

1:18

within a few research studies at my institution.

1:23

And I thought that having these cases will

1:27

help you, uh, put together a contrast

1:29

mammography and digital breast tomosynthesis set

1:33

side by side. DBT, or digital breast tomosynthesis,

1:37

is not a part of contrast-enhanced mammography.

1:41

Contrast mammography is really a 2D exam,

1:44

but we do them together just for research

1:47

purposes, and by putting them together here,

1:50

I thought that, uh, that could help you compare,

1:55

correlate and see if you find that, uh, DBT might play

2:00

a role in your practice alongside the contrast enhanced

2:04

mammography and how those findings correlate.

2:07

And again, uh, remember that contrast mammography

2:10

on its own is a 2D exam, but there is a possibility

2:15

to do, uh, DBT and contrast

2:18

mammography under the same compression.

2:21

But whenever you decide to do that,

2:23

uh, you would have to do DBT first.

2:26

Of course, remember that it

2:27

does add some radiation dose.

2:30

And this is just an example of how it looks like.

2:33

Uh, this is the same case, a craniocaudal

2:35

view of the right breast on the left.

2:38

It's a DBT slice, and you might recognize that in

2:42

this particular slice you see some findings in focus.

2:46

So this is a low energy image, which

2:49

is just like Dr. Phillips mentioned.

2:52

It's equivalent to our regular

2:54

full-field digital mammogram.

2:56

And of course, it's a cleaner image, so you don't

2:59

see those edges as well as on the DBT slice.

3:03

And on the right is our recombined image, and this is

3:08

the image of a contrast distribution in the breast.

3:12

And of course, you see immediately at a glance the

3:15

extent of disease, all those multiple masses and

3:18

non-mass enhancement, and how well it helps us

3:21

delineate the extent of disease in this breast.
