Hello and welcome to Noon Conference hosted by MRI Online. In response to
0:07
the changes happening around the world right now and the shutting down of
0:10
in person events, we have decided to provide free Noon Conferences to all
0:15
radiologists worldwide. Today, we are joined by Dr. Michael Fishman. Dr.
0:20
Fishman is a breast imaging radiologist at Boston Medical Center interested
0:25
in artificial intelligence and social determinants of health. Also a trained
0:31
health and wellness coach, he develop both a wellness/non clinical skills
0:36
curriculum and a coaching program for residents. A reminder that there will
0:40
be a Q&A session at the end of the lecture, so please use
0:44
the Q&A feature to ask your questions and we will get to as
0:46
many as we can before our time is up. That being said,
0:50
thank you all for joining us today. Dr. Fishman, I will let you
0:54
take it from here. Hopefully everyone can see my
0:59
slide. Thank you so much for that introduction and welcome to everybody
1:04
who is joining us today from near and far. I encourage you
1:09
just so that I can get a sense of who our audience is,
1:12
feel free to put into the Q&A where you are from and
1:17
whether you are a resident or an attending and
1:22
what specialty you are thinking about going into if you are a trainee or
1:26
a fellow for that matter. So I wanted to talk a little bit
1:29
about Rad Path correlation, which is something that we do in breast imaging
1:33
all the time. Primarily at the time of the biopsy or when we
1:40
get the pathology back, some institutions like our own have a specific Rad
1:47
Path correlation conference that they hold at regular intervals to discuss
1:54
either all biopsy cases or particularly challenging cases where there may
1:59
be an interesting lesson learned. So we are going to just jump into
2:04
it. The goal for today is to talk about
2:07
concordance for benign and malignant diagnoses to identify when discordance
2:14
might be suspected and when there may be additional sampling needed and
2:19
to review management for some areas that are a little bit more controversial
2:26
recently. So just in general, as you hopefully are all aware,
2:31
there are lots of different ways to perform biopsies.
2:34
What we do in radiology is minimally invasive relative to surgery and there
2:39
are lots of different modalities that can guide our images and our procedures.
2:46
Primarily in breast imaging, we use mammography with stereotactic biopsies
2:51
and with ultrasound core biopsies. And there's lots of other procedures
2:56
that have been developed, not specifically for diagnoses per se, but sometimes
3:01
for presurgical planning. The advantages of the core biopsy relative to
3:07
surgery is that they're very accurate in making the diagnosis and
3:13
most importantly, they're able to differentiate invasive from in situ carcinoma,
3:19
which is generally different than an FNA as well as receptor status for
3:25
cancer diagnoses, which help guide treatment. In addition, it's very fast,
3:31
we can do these sometimes as quickly as 10, 15 minutes.
3:35
They're much less costly than surgery, there's less
3:38
pain, there's minimal recovery time for most patients.
3:44
And when we are able to make a diagnosis before surgery,
3:49
it really optimizes oncologic management. And recently, at least at our
3:55
institution, there's been a lot more neoadjuvant chemotherapy being performed.
4:01
And so I'm curious to hear about whether that is happening at your
4:05
institutions as well. So again, lots of different modalities to use,
4:11
most commonly are ultrasound core biopsies. In general, they're more comfortable
4:16
for patients and very fast to perform. So
4:24
what we do is we perform the biopsy, send the tissues to the
4:27
pathologist, and then coming back, we want to look at the diagnosis that
4:34
the pathologist sends us and determine whether or not it is concordant,
4:38
whether it sort of matches up with what we expected on the imaging
4:42
findings. So when we're looking at the imaging, not only do we categorize
4:46
it as suspicious with the BioEds 4 or 5, but we also have
4:50
in our mind a differential diagnosis for whatever lesion it is,
4:55
whether it's a mass or calcifications or an asymmetry, as to what that
5:01
target lesion may or may not represent. So
5:05
we may expect a cancer, and if the diagnosis is not a cancer,
5:10
then it calls into question whether or not the results are concordant.
5:15
So it's important to communicate these findings reliably both from the pathologist
5:20
back to the radiologist and then both from the radiologist back to
5:25
sometimes the referring physician, sometimes the patient, and to addend
5:32
the report with management recommendations. And the documentation is really
5:36
critical in this case. So we're not going to do this poll everywhere,
5:43
but we're going to start looking at some of the cases.
5:46
And the first case is a 41 year old woman who's having her
5:50
baseline screening mammogram. As many of you may know, the American College
5:55
of Radiology recommends screening to begin at age 40 for average risk women.
5:59
In other countries, those recommendations may be different based on
6:05
radiology societies and other medical societies in your countries.
6:10
No other history for this patient. So this patient,
6:16
just to give you a second to look at it, she has heterogeneously dense breast
6:20
tissue. She has calcifications that are in the lower inner quadrant of the
6:25
left breast. So she was called back for workup of those,
6:29
and these are magnification views that were taken at that time.
6:32
And some of these are loose and centered, suggesting that they're dermal
6:36
calcifications, and other calcifications are more coarse heterogeneous.
6:40
Coarse heterogeneous calcifications have a certain connotation. So the question
6:45
is, what is the recommendation for those calcifications? Do we
6:52
think that they're benign and return the patient to screening? Do we think
6:56
they're probably benign and never come back in six months for follow up?
