As important is to talk about the findings

0:03

that are appropriate to give a BI-RADS 3.

0:05

I think I also just wanted to point out that we

0:08

want to be clear when there are findings that

0:11

are safe to call a BI-RADS 2 and to let the

0:14

patient go a whole year before additional imaging.

0:17

And I thought this was a good example because it sort

0:19

of follows from those kind of post-trauma, post-surgical

0:22

cases that I showed on mammogram or ultrasound.

0:25

This is a patient who had had a lumpectomy

0:27

in her left breast, and we see a very,

0:30

very classic appearance of fat necrosis.

0:32

So,

0:35

here is the area of surgery,

0:37

and we see this fat intensity.

0:41

This is bright on the T1 non-fat saturated sequence.

0:47

When we look at the fat-saturated

0:53

sequence, we see that the area that was

0:54

bright on the non-fat saturated sequence

0:57

is now dark, confirming that it is fat

1:02

that makes it up.

1:03

And on the post-contrast subtraction image,

1:07

we see a little bit of enhancement sort of around

1:09

the edge of it, but it's a very thin enhancement.

1:13

There's nothing mass-like.

1:16

There is a thing that looks nodular.

1:18

This is very typical for post-surgical

1:21

changes at a lumpectomy site, and this

1:23

can very safely be given a BI-RADS 2.

1:25

We don't need to give this a BI-RADS 3.
