🔥Chinese RCT shows PCSK9i in severe ICAD can reduce plaque thickness and luminal stenosis! (No surprise, but will be useful to justify this tx for our high risk patients!!) @ahascience.bsky.social #ISC25 @teachplaygrub.bsky.social @ericajonesmd.bsky.social @strokeupmc.bsky.social
Are you right when it’s bright? Bright cortex on DWI is classically anoxic injury But mimics exist! 6 patterns -Cortex+deep gray -Diffuse Cortex -Focal Cortex -Limbic -Deep gray -WM Ask 3 ?’s: -Acute or chronic? -Acute=metabolic & anoxic. Sz & encephalitis rarer & focal -Chronic, think CJD

1/Have you been cutting corners when it comes to coronal anatomy? Do you just say a lesion is in the inferior frontal region & hope no one asks for details? It’s time to turn the corner on coronal anatomy Open this thread for an easy way to remember this frontal anatomy you need to know!

1/ “Tell me where it hurts” How back pain radiates can tell you where a lesion is—if you know where to look! Do YOU know where to look? Open this thread to see how to remember lumbar radicular pain distributions! And keep this cheat sheet as a BACKUP for when you are dealing w/back pain!

1/Sink or swim! Brain is swimming in CSF! CSF is key for protection, buoyancy, & hormone/waste transport Most know basic ventricular anatomy, but not subarachnoid anatomy How many cisterns do YOU know? Open this thread for a quick guide to the key midline cisterns & what to know for each!

1/Just because it’s called SMALL vessel disease doesn’t mean it doesn’t have a BIG impact! Small vessel disease (SVD) is a BIG contributor to vascular dementia, along w/large vessel cortical infarcts Do YOU know all the faces of small vessel disease? Open the thread for what you need to know!

Is looking at dementia PETs one of your PET peeves? Main patterns 🔹AD Nike swoosh—if you see it, just call it! 🔹DLB Hypometabolism looks like an L. L=Lewy 🔹FTD Ant cingulate role makes an f. f=ftd 🔹Posterior cortical atrophy Anterior temporal sparing makes a C=pCa 🔹Vascular dementia Wedge shaped Vs

Can you only remember temporal anatomy temporarily? It looks like a parfait! Heschl’s is strawberry on top 🔸Heschl sounds like bushel—& bushels=fruit Parfait layers=sup, mid, & inf gyri Glass stem is fusiform gyrus 🔸Stem has fusiform shape! Now your understanding will be, well, parfait!!

Does trying to figure out aphasia leave you speechless? At a loss for words for aphasia types? Remember 3 ?'s: 1. Fluency? Nonfluency=FRONTAL, ant. to fissure of Rolando 2. Comprehension? Impaired=TEMPOROPARIETAL 3. Repetition? Impaired=core PERISYLVIAN Answers give aphasia type & location!

1/ How durable is your knowledge of dural lesions? How’s your knowledge base of the skull base? Know the difference between petroclival & petrous face? Middle fossa & middle sphenoid wing? Clinoid & clivus? Here is a map of the names of skull base meningiomas. How many do you know?

It literally took my radiologist husband a full minute to figure out what was wrong about this picture! How long will it take YOU?? And can you spot the abnormality? Here’s to a year of high resolutions—both in imaging and for New Year’s! Wishing you all the best in 2025!

Can’t metabolize all the metabolic bone diseases? When you see weird bones, do you just say, “suggestive of metabolic bone disease” & hope no one ask questions? Metabolic disease are complex but a few are a slam dunk Bookmark this figure for the 4 classic xray patterns you NEED to know!

1/Knowing spinal arterial anatomy is a given. Knowing spinal venous anatomy is next level Vertebral venous plexus can be both good & evil--good for collaterals, bad for tumor spread, infxn, & emboli...and spinal CSF fistulas! Here’s the anatomy you MUST know if you are doing spine

Wish that your knowledge of autoimmune encephalitis was automatic? Do you feel in limbo when it comes to the causes of limbic encephalitis? Do you know the causes? Or the other patterns of autoimmune encephalitis? Here’s a short video and some hints to help you figure it all out!
1/Season’s Greetings & Happy Arteries! Have you ever noticed how the cerebral arteries branch just like the antlers of a deer? Coincidence? Or is there a reason? Have you ever wondered why? What could drive 2 things so different to look so alike? Answer may surprise you!!
