- In our other video we talked about
patient position and transducer orientation,
and in this video I'd like to talk about
inputting information into the ultrasound machine
and how to go about acquiring a measurement.
So, on the ultrasound machine,
one of the things that's different about IMT as
compared to some of the other examinations,
is that there is some information that
you really need to have input into the system.
It's very important to have the patient gender input
into the system because the restratification
gets applied according to male or female,
and the date of birth,
that's information that is very important as well.
Ethnicity is an option that's offered for IMT only,
and that's relative to the restratification,
so you always wanna have that information selected.
You also wanna be sure you have the IMT exam selected.
Once you get all that information input
you can begin with your study and know that
when the study is completed,
that information will automatically be populated
into the patient report for SonoCalc.
You wanna take your measurements from the distal portion
of the common carotid artery just before the bifurcation.
So, when you're acquiring your measurements,
you will always be scanning in the longitudinal plane.
You'll have the artery in long,
and you wanna get a nice image of the IMT.
You don't wanna take your measurement within the bulb.
Depending on your protocol,
you'll take measurements from the near wall
and the far wall.
So, when you have a good image of the IMT
you'll freeze the image,
select the calcs,
then you wanna select the IMT measurement tool,
and you'll get this drop down menu that gives you
options of which angle are you scanning from,
and when you select the label, the tool will come up.
And you just select the direction that
you need to move the tool,
whether it's left and right,
or up and down.
And you bring the tool down and it should attach
onto the arterial wall,
and the measurement will automatically be displayed
on the bottom of the screen.
This is a far wall measurement.
Now I'll show you how to acquire a near wall measurement.
Near wall measurement is, again,
taken at the distal portion of the common carotid artery
just prior to the bifurcation.
You wanna select the calcs.
And when you select your label,
you wanna select a label that has N
for near wall measurement.
When the tool comes up...
You can bring it down.
Move it left to right.
If you need to make an adjustment of the measurements,
we're gonna here adjust the lumen line,
select the lumen,
turn the dial and make the adjustment,
and again, across the bottom of the screen
the measurement results are displayed.
The right side, lateral, and you have N,
indicating that this is a near wall measurement.
So, when you're looking at the measurement
you will notice a little portion
of the measurement line is blue.
That's identifying the thickest portion of the measurement.
The max region correlates to this little blue line.
The maximal thickness of this measurement.
When you acquire your measurements,
it's important to remember to hit the save key
so that those measurements will be populated
in the report page.
To view your report at the end of an exam
select the more key, and report.
And all measurements that have been saved
will be populated in the report.
The individual measurement results can be displayed,
as well as the summary averaging all measurements
that have been acquired.
In summary, the IMT exam is done bilaterally,
and you want to make sure that you image the patient
from all recommended angles,
anterior, lateral, and posterior.
And remember, according to your protocol,
you can evaluate the near wall as well as the far wall.

- I'd like to walk you through a demonstration
of scanning the Carotid Artery for CIMT.
One of the things that's really important
is to position yourself as well as the patient comfortably.
I like to scan from the patient's head,
but many people like to scan coming from the foot.
So, when you're scanning from the patient's head,
you wanna position the height of the table
so that it's comfortable and you're not
holding your arms up in an uncomfortable manner.
You wanna have the patient lying
with their head turned away from you.
So, whichever side your scanning,
have the patient turn their head away.
So, we like to start this exam
with a transverse orientation.
You want to start low in the neck
with the orientation marker facing toward
the patient's back down toward the bed.
Scan up the neck in a transverse orientation.
The vessel should be nice and round.
And you'll be able to see the Carotid Artery,
the thyroid gland.
And oftentimes, you'll be able to see the Jugular Vein.
Continue to scan up the neck in a transverse manner
and when you start to see the vessel get wide,
then you know you're in the Bulb.
And you wanna continue through scanning
to see the internal and the external Carotid Artery.
You wanna scan the patient from three different angles.
You wanna scan from the Anterior Aspect of the neck,
it's roughly 2 o'clock.
Then from the Lateral Aspect of the neck,
that's probably about 4 o'clock.
And then from a Posterior Aspect of the neck,
which is probably about 5 o'clock.
Three angles, Anterior, Lateral, and Posterior.
Then, you want to turn the patient's head
so that it's facing in the other direction
and you wanna perform the same exam
from the opposite side of the neck.
Now, when you're scanning from
the opposite side of the neck,
the orientation marker stays
the same way it was from the opposite direction.
And you want to scan up again, transverse manner.
Artery should be nice and round.
And again, you're looking for
the widening of the artery wall
to let you know that you're at the Bulb.
Scan through the bifurcation of the
internal and external Carotid Artery.
And you wanna turn the transducer
to a longitudinal orientation.
Again, with the orientation marker
pointing toward the patient's head.
And on this side, again, you want to come from three angles.
From the Anterior approach, roughly 2 o'clock.
From the Lateral approach, about 4 o'clock.
And from a Posterior approach, about 5 o'clock.
So, in summary, the Carotid CIMT Exam
is a Bilateral Exam.
You want to be sure to evaluate
both sides of the patient's neck.
And you wanna come from as many angles as possible.
You wanna come from the Anterior approach,
from the Lateral approach,
and from the Posterior approach
on both sides of the patient's neck.
