Answer 3

RE-DO

What are EEG’s good for?

Answer 5

Dx of szrs, certain neurological disorders and ALOC

Question 6

What can EMG’s Dx?

Answer 6

they can detect disorders of the motor units and can indicate the underlying lesion. provide a guide to prognosis

Question 7

What types of things does nerve conduction studies help Dx?

Answer 7

they confirm the presence and extent of peripheral nerve damage.

Question 8

True or False: nerve conduction studies can confirm whether sensory Sx are caused by a lesion proximal or distal to the DRG.

Answer 8

TRUE

Question 9

If a patient presents with mononeuropathy, what can nerve conduction studies also detect?

Answer 9

subclinical involvement of other peripheral nerves

Question 10

True or False: unfortunately nerve conduction studies cant distinguish between a polyneuropathy and mononeuropathy multiplex.

Answer 10

FALSE

Question 11

Nerve conduction studies can see what cause of polyneuropathies?

Answer 11

Compression focal neuropathies

Question 12

In axonal neuropathies, is nerve conduction increased or decreased?

Answer 12

Normal (myelin is A-OK)

Question 13

In demyelinating diseases, is nerve conduction increased or decreased?

Answer 13

Decreased

Question 14

What can MRI’s detect in strokes?

Answer 14

If used early-cerebral infarcts

If used for 2-3 days- hematomas

Question 15

What can CT’s see in strokes?

Answer 15

After 48 hrs, can see hemorrhage

Question 16

What can MRI’s see for tumors?

Answer 16

Everything. MRI’s are like super good at seeing tumors.

Question 17

Answer 17

Can see the tumor but is also good for herniations.

Question 18

Wen do you use MRI’s for trauma?

Answer 18

Good for follow-ups, but nothing acutely.

Question 19

What can u use CT’s for trauma?

Answer 19

Good for acute things, like intracranial hemorrhage.

Question 20

What can MRI’s show for dementia?

Answer 20

Can see abnormal white matter and atrophy

Question 21

What can CT’s see for dementia?

Answer 21

Nothing really. CT’s suck harder for dementia than a cheap hooker using a vacuum.

Question 22

What can MRI’s see for MS?

Answer 22

Detect demyelinating lesions in the white matter or spinal cord.

Gadolinium MRI shows lesions of different ages.

Question 23

What can CT’s show for MS?

Answer 23

NOTHING. GOD CT IS HORRIBLE (except trauma)

Question 24

What can MRI’s show for infections?

Answer 24

White matter edema, focal areas of cerebritis and abscess formation.

Question 25

What can CT’s see for infections?

Answer 25

NOT MUCH OMG CT’S WTF
