1

what do you look for a pathology in imaging?

 

midline, shift, asymmetry

2

is this MRI, CT, XRay...

 

at what level?

CT

 

left: lateral ventricles so it is very superior

right: brainstem level (the eyeballs are present)

3

which will be anatomical: T1 or T2?

anatomical = white matter is white, grey matter is grey

T1 is anatomical

 

4

Is this T1 or T2?

 

 

T-1


 

 

5

is this T1 or T2?

T 1

6

is this T1 or T2?

T2

7

Which  machine uses T1/T2?

MRI

8

identify how the things look in the image

9

answer

10

answer

1) anterior commissure

2) interthalamic adhesion

3) third ventricle 

4) spleneium 

5) cingulate gyrus 

11

answer

12

What is Flow Void?

In which imaging can you see it and how does it look?

Flowing blood (not bleeding) appears dark on a T2 but not on CT/T1.

 

 

13

answer

14

a bleed is always what color in all CT and MRI?

infarcts, tumors and MS plaque are dark in which?

MRI T1, MRI T2, CT

 

bright

T1 and CT

15

is this T1, T2, CT?

what is the pathology?

 

CT

epidural hematoma

16

is this T1, T2, CT?

What is the pathology?

T1

sub-arachnoid bleed

17

is this T1 or T2, or CT?

pathology?

T1

shaken baby = right is old blood, left is new blood

18

what 2 enhancement can you use for T2?

what do they do?

  1. Proton density (T2-PD)
  2. FLAIR

 

better resolution near the ventricles

19

what enhancements can be used for T1?

when do you use it?

 

what enhancements can we use for strokes?

just GAD for tumors

 

DWI and PWI

20

what is the pathology?

is this CT or MRI?

 

hemorrhage

CT

 

21

if someone has a hemmorrhage, what imaging is the best?

 

If someone has an infarct, is CT good for that?

CT

 

 

no

22

what is the pathology here?

what imagin is being used?

subdural hematomas

CT

 

23

what type of image?

what is the pathology?

what enhancement is used?

 

CT

stroke

DWI

24

what type of image is this?

how do you know?

what is the enhancement?

 

T2

CSF is very bright

none

25

what is the type of image?

what type of enhancement?

what is the pathology?

which artery would be damaged?

T2

FLAIR

infarct on left lower side (spots)

Left MCA

26

what does PWI measure?

what does DWI measure?

change in cerebral blood flow

extent of diffusion of water in short distance

27

what enhancement is used?

DWI and a FLAIR

28

DWI and PWI are good for measuring what?

 

extent of an infarct

 

29

what is this imaging?

what is the pathology?

angiogram

right internal carotid occlusion

30

which area is underperfused?

what should you do?

 

the right side in blue

give clot buster
