1 m.0:00
So in terms of CAD and AI, um, CAD was initially
0:04
approved, uh, by the FDA in 1998 for use in
0:06
2D mammography. There's two different types of CAD,
0:10
uh, if you get into the details of it.
0:12
Uh, there's CAD-E, which is computer-aided detection,
0:15
which helps us to identify abnormalities, and there's
0:18
CAD-X, which is computer-aided diagnosis, meaning that
0:20
it classifies those abnormalities into, let's say...
0:25
CAD algorithms were originally
0:27
developed using supervised learning.
0:29
Um, were trained on datasets with known
0:31
pathology, and the radiologists who were
0:33
involved in those studies assessed positivity,
0:36
which overall led to some verification bias
0:38
and increased false positives over time.
0:41
Uh, I think the benefits of CAD have
0:44
been sort of whittled down, and so most
0:46
practices are probably not using CAD
0:51
as perhaps fully intended or doesn't
0:52
really help improve their performance.
0:55
But CAD based on AI, uh, does offer some
0:59
potential improvements over standard CAD.
1:02
Uh, in terms of training the algorithm, there's
1:05
unsupervised learning, meaning that AI is not
1:07
bound to radiologists for determination of truth.
1:10
Um, and that we can also have the potential
1:12
to do quantitative image analysis and to
1:14
see what the radiologist cannot see, right?
1:16
So it may look for all of us as radiologists for
1:19
all this, all the world looks exactly the same, but
1:21
the AI algorithm may pick up some area where there's
1:24
some underlying sort of abnormality or feature
1:29
that identifies that we can't really even perceive.
1:32
Um, so there's a lot of benefit for that.
1:34
Um, it's just being, starting to use it out
1:37
there in clinical practice or, um, being tested.
1:40
Um, and a lot of it remains kind of unknown
1:42
where, where CAD will end up with, uh, in.
