00:00:08.116 --> 00:00:10.746 align:start
>> So in radiology, there's
different technologies

00:00:10.746 --> 00:00:12.596 align:start
that we can use to
image the human body,

00:00:12.596 --> 00:00:13.976 align:start
and in our case, the brain.

00:00:13.976 --> 00:00:16.476 align:start
The most commonly
studied technologies

00:00:16.476 --> 00:00:19.856 align:start
for studying the brain are
going to be MRI, which stands

00:00:19.856 --> 00:00:22.686 align:start
for Magnetic Resonance
Imaging, and PET which stands

00:00:22.686 --> 00:00:24.726 align:start
for Positron Emission
Tomography.

00:00:24.846 --> 00:00:29.036 align:start
What MRI does is it uses a
very powerful magnet as well

00:00:29.036 --> 00:00:31.166 align:start
as radio frequency
waves, the same kind

00:00:31.166 --> 00:00:33.316 align:start
of radio frequency waves that
you listen to your car radio

00:00:33.316 --> 00:00:36.446 align:start
on for example, to generate
images of the human body.

00:00:37.086 --> 00:00:39.056 align:start
It's very good at showing
structural information

00:00:39.056 --> 00:00:39.606 align:start
about the brain.

00:00:40.006 --> 00:00:42.456 align:start
There's essentially no
preparation except maybe letting

00:00:42.456 --> 00:00:44.986 align:start
us know what kind of
metal or electronics

00:00:44.986 --> 00:00:46.026 align:start
that you might have
in your body.

00:00:46.836 --> 00:00:49.306 align:start
If you have something implanted,
it's important that you find

00:00:49.306 --> 00:00:51.906 align:start
out what's the make and
model of that implant

00:00:51.906 --> 00:00:54.296 align:start
so that we can look it up, and
make sure that it's MRI safe.

00:00:55.096 --> 00:00:57.786 align:start
Once you get to the MRI
check-in area, we'll ask you

00:00:57.786 --> 00:01:00.276 align:start
to take all electronics and
metal out of your pockets.

00:01:00.276 --> 00:01:02.706 align:start
Anything that can be
removed should be removed,

00:01:02.756 --> 00:01:04.636 align:start
and we'll change you
into a hospital gown

00:01:04.636 --> 00:01:06.416 align:start
for the duration of the scan.

00:01:06.556 --> 00:01:09.266 align:start
PET has the advantage of showing

00:01:09.266 --> 00:01:12.276 align:start
where specific molecules are
being taken up by the brain.

00:01:12.706 --> 00:01:14.826 align:start
That's why PET imaging
is also often known

00:01:14.826 --> 00:01:15.806 align:start
as Molecular Imaging.

00:01:16.606 --> 00:01:19.256 align:start
For PET what we do is we
inject a radioactive tracer

00:01:19.536 --> 00:01:20.096 align:start
into the body.

00:01:20.736 --> 00:01:23.356 align:start
This radioactive tracer
usually decays pretty rapidly,

00:01:23.356 --> 00:01:24.936 align:start
so that you're no
longer radioactive

00:01:25.136 --> 00:01:26.936 align:start
after a short period of time.

00:01:27.076 --> 00:01:29.216 align:start
This radioactive tracer is
taken up by different tissues

00:01:29.216 --> 00:01:32.346 align:start
in the body, and that lets us
generate images of the brain

00:01:32.586 --> 00:01:34.246 align:start
through a different mechanism.

00:01:34.246 --> 00:01:36.886 align:start
The more information we gather
by using these techniques both

00:01:36.886 --> 00:01:39.916 align:start
in healthy and unhealthy
brains, symptomatic

00:01:40.096 --> 00:01:42.946 align:start
and unsymptomatic brains, the
faster we'll be able to get

00:01:42.946 --> 00:01:44.836 align:start
to an answer about how
these can help patients

00:01:44.836 --> 00:01:46.226 align:start
who are exposed to
trauma or stress.

00:01:46.976 --> 00:01:49.126 align:start
>> The Image Processing
Core develops

00:01:49.316 --> 00:01:55.166 align:start
and applies computer algorithms
to help extract information

00:01:55.306 --> 00:02:00.156 align:start
from medical images that are
acquired through MRI or PET.

00:02:00.876 --> 00:02:04.206 align:start
So, CNRM was one of
the first installations

00:02:04.396 --> 00:02:06.596 align:start
of a simultaneous
PET MRI scanner

00:02:06.596 --> 00:02:08.086 align:start
within the United States.

00:02:08.826 --> 00:02:12.656 align:start
So, our group has developed
a patent pending procedure

00:02:12.686 --> 00:02:15.646 align:start
to actually see missing
connections perhaps,

00:02:15.646 --> 00:02:16.816 align:start
or shortened connections.

00:02:17.226 --> 00:02:19.056 align:start
And then there's
also a large number

00:02:19.056 --> 00:02:20.576 align:start
of quantitative measurements

00:02:20.756 --> 00:02:23.076 align:start
that characterizes
how well connected --

00:02:23.676 --> 00:02:25.296 align:start
different regions within
the brain are connected

00:02:25.296 --> 00:02:25.756 align:start
to each other.

00:02:25.756 --> 00:02:28.366 align:start
And we can compare that
across individuals,

00:02:28.476 --> 00:02:31.376 align:start
between healthy individuals
and unhealthy individuals,

00:02:31.376 --> 00:02:33.086 align:start
and see what the
differences are.

00:02:33.336 --> 00:02:35.376 align:start
So, if there's a healing process

00:02:35.376 --> 00:02:37.586 align:start
or repairing process
we can monitor that.

00:02:37.896 --> 00:02:40.946 align:start
Especially if there's a
therapy that's being administered

00:02:40.996 --> 00:02:42.026 align:start
to a patient.
