Hello everybody.

0:02

My name is Dave Sso

0:03

and I'm gonna be teaching you today about

0:06

emergency neuroimaging.

0:08

The goal today is to prepare radiologists either in training

0:13

or otherwise for neuroradiology cases that they would expect

0:16

to see in an emergency department.

0:20

I'm going to do this course a little bit differently in

0:22

that it's gonna be organized not by my usual vitamin C

0:25

and D for those of you who know me, vitamin C

0:28

and D, standing for vascular, infectious, traumatic,

0:32

acquired metabolic idiopathic neoplastic, congenital

0:34

and drugs, categories of pathology.

0:37

Instead, we're gonna organize it by the typical

0:40

clinical scenarios that you see

0:42

for cases in the emergency department,

0:45

and hopefully I'll provide some tips for avoiding some

0:48

of the pitfalls of emergency neuroimaging.

0:52

These six clinical emergency department scenarios

0:56

that will encompass about 95% of

0:59

what you read in the emergency department include,

1:03

number one, a new neurologic deficit.

1:05

So-called TIA, or stroke head trauma.

1:08

This for all those motor vehicle collisions as well

1:10

as patient falls.

1:13

Uh, worse headache of life.

1:15

Again, migraineur who come in with the worst headache

1:18

of their life, or patients potentially

1:20

who have intracranial hemorrhage,

1:22

who have the worst headache of life.

1:24

Number four, found down or change in mental status A MS.

1:29

You'll see that on a lot of the requests

1:31

for the emergency department,

1:32

and that's altered mental status.

1:35

And that may be a patient who is drunk and is found down

1:39

or has used intravenous agents, drug abuse, for example,

1:44

or someone who is just unconscious.

1:47

Number five is a little bit less common.

1:49

That's a patient with a fever and

1:51

or someone who presents with a seizure.

1:54

And the last case is more on the pediatric side.

1:57

And as patients who have ventricular peritoneal shunts,

2:00

you'll see it Stass, VPS, new lethargy.

2:04

So patients who, children who have shunts often come in

2:07

with maybe just the flu symptoms,

2:09

but they're concerned about whether there is shunt failure.

2:12

So with these six clinical emergency department scenarios,

2:16

I think you're gonna cover, as I said, 90 to 95%

2:20

of the cases that you'll see in the ed.
