1 m.0:01
So in this case here, uh, I'm showing, uh, images
0:04
of the right breast in the CC and MLO projection.
0:09
On this exam, uh, we see diffuse round coarse
0:14
heterogeneous calcifications, the right breast
0:16
at 10 o'clock for the middle to posterior depth.
0:18
As we scroll through the, uh, to
0:21
of this image dataset, right?
0:23
We can see those calcifications appear
0:24
in multiple different planes, and
0:27
some of them you might get the sense.
0:30
Stop here.
0:30
That, like, for example, this calcification here,
0:33
uh, we see a little bit of that slinky artifact, but
0:35
it looks like it changes directions that may, might
0:38
make you wonder a little bit about motion artifact.
0:42
We go back to the SM, uh, view.
0:45
We can see those calcifications and we can see
0:46
the corresponding ones in the right MLO view.
0:51
Um, I'm gonna pull up for comparison a more
0:54
recent, um, SM view from the same patient.
0:57
This is about a year later, and we can see
1:00
in this similar part of the breast, outer
1:01
part of the right breast on the CC view.
1:03
There seems to be a lot more
1:04
calcifications in this area.
1:06
I think what has happened here, um, is I don't
1:09
think that these are new calcifications, but
1:11
what we are seeing here on this right CC view
1:13
from before is that motion artifact has obscured
1:17
or removed the calcifications from our view.
1:20
So despite the fact that we felt like we had to
1:21
call this patient back for some potentially new
1:23
or increasing calcifications, that really these
1:26
calcifications were likely related to the fact that
1:28
there was motion artifact in the CC that obscured.
