Feeling nervous when it comes to nerve imaging?

MR neurography is becoming standard

If you don’t know how to read it, it can be nerve-wracking!

Here’s the cheat sheet you NEED to be able to read these studies!

Read on for the newest SCANtastic:

Here's an easy way to remember the different injury grades on MR neurography:

➡️Class I injury: Neuropraxia
🔸Myelin is injured, but nerve is intact
🔸Nerve is bright on imaging, but normal in size
🌟Remember:
▶️Roman numeral 1 (I) looks like the normal axon of a nerve. Nerve looks normal on imaging except for increased T2 signal

➡️Class II/III injury: Axonotmesis
🔸Axon disrupted, but connective tissue intact
🔸Nerve is both bright & enlarged
🌟Remember:
▶️Roman numerals II & III look just like Roman numeral I but thicker. Nerve is both bright & thickened

➡️Class IV injury: Neuroma in continuity
🔸Only endoneurium is intact
🔸Nerve has focal thickening/neuroma
🌟Remember:
▶️Roman numeral IV is the Roman numerals I & V. Roman number I looks like a nerve & Roman numeral V looks like a sideways scissors. So IV is a nerve that is almost cut completely by scissors

➡️Class V injury: Neurotmesis
🔸Nerve is severed
🔸Nerve shows discontinuity
🌟Remember:
▶️Only the V or scissors remain. No Roman numeral I here for a nerve, so nerve is completely severed & only the scissors remain

Hopefully, these tricks strike a nerve & help you remember the findings of nerve injury on imaging!

With this cheat sheet, you won’t have any trouble getting up the nerve to read MR neurography!

The stroke neurologist is never fully satisfied with ESUS. Rather than repeating loop recorders they look for:

- occult cancer
- branch artery disease
- aortic arch athero
- non-stenotic extracranial large artery athero
- minor valve disease
- LV wall motion abnormalities
- carotid siphon disease
- atrial cardiopathy without Afib
- non-ischemic cardiomyopathy
- hyperhomocysteinemia
