Case: Normal HRCT

HIDE
PrevNext

0:01

Here's an example of a near normal HRCT.

0:04

So here's the inspiratory phase.

0:06

We've done a volumetric acquisition reconstructed very thin.

0:09

These are 1.25 millimeters thin. I like 'em.

0:12

Maybe a little thinner than this, but it's okay.

0:15

See a little bit of motion artifact at the lung base.

0:16

That's just par for the course.

0:18

And there's some scattered nodules,

0:19

but this is as good as you're gonna get in terms of looking

0:23

for fine detail within the lung parenchyma.

0:27

And then I said before, we are going

0:30

to do expiratory series here as well.

0:33

And here's example of a nice expiratory series.

0:35

Lemme mag it up a little bit. These commonly will have

0:39

more motion artifact, as you could see here.

0:41

So good amount of motion artifact here at the lung basis.

0:44

And you just had kind of have to, this is real life,

0:46

you just kinda have to read through it.

0:47

This is the way it is. But you notice the lungs turn

0:50

homogeneously gray here, and that makes sense, right?

0:53

So when the lungs have less gas within them,

0:55

they're gonna become more hyperdense.

0:58

And very commonly you're gonna see augmentation

1:02

of the trachea, specifically the posterior wall.

1:04

The trachea is gonna be sort of convex forward,

1:07

and that's an indication that you're indeed dealing

1:09

with a expiratory case.

1:11

It's a nice example here of a normal ct.
