Traumatic brain injury,

0:02

which we often refer to as TBI,

0:05

affects over 10 million people worldwide each year.

0:10

It is the most common cause for head CT after

0:14

headache in the emergency department.

0:17

Number three would be mental status change,

0:20

at least in our practice,

0:21

often that may be due to either drug use or alcoholism.

0:26

It is the leading cause of central nervous system

0:28

morbidity in patients less than 40 years of age and seems

0:33

to be increasing as we have increasing motor vehicle

0:36

collisions, as well as other forms of transportation

0:40

that are being employed each year.

0:42

Concussion and mild traumatic brain injury are all the rage

0:47

with regard to research and this is

0:50

also included in sports injuries.

0:53

In this course, I will talk about the various appearances

0:56

of traumatic injuries to the brain on both CT and MRI.

1:01

I will stress the indications for surgery that should be

1:05

included in your reports when you are dictating cases,

1:09

either on CT or MRI in patients who

1:12

have had traumatic brain injury.

1:13

We will also discuss the phenomenon of primary injury

1:17

versus secondary injury,

1:18

with the understanding that most patients

1:20

who die from traumatic brain injury, die from the

1:24

secondary injuries rather than the initial primary injury.

1:27

And finally,

1:28

I would talk to you about the basics of hemorrhage with

1:32

regard to the causes of the different signal intensity

1:35

characteristics on MRI and the density

1:38

characteristics of hemorrhage on CT.
