Anyone can see the bright spot on diffusion—what sets you apart is if you can tell them why it’s there!

Can you tell a stroke’s etiology from its appearance on MRI?

Main stroke types:

Artery to artery embolism
—Vulnerable plaque ruptures & causes clot formation
—Occludes the artery & distal blood flow
—Makes a wedge shape

Distal hypoperfusion:
—At the border zones
—Remember borderzones almost look like a fancy letter H for Hypoperfusion = two vertical lines (ant, internal watershed) that have curls at each end (ant & post external watersheds)

Vasculitis
—Inflammation ofvessel wall
—Idiopathic, autoimmune, or infectious
—Remember: Vascu-LIGHT-us = tons of little regions LIGHT up on DWI
—Remember Vascu-LITE-us = usually in LITE vessels or small vessel territories

Impingement on perforators:
—Large vessel plaque covers opening of small perforator in its wall
—Perforators affect the Ps = pons, putamen (lenticulostriate)

Small vessel dz
—Many different pathologies that cause occlusion of small, unnamed vessels
—Remember: Small & subcortical both start w/—tend to be subcortical

Cardioembolic
—Emboli from heart stasis or vegetations
—Remember: Emboli & everywhere both start w/E = emboli go everywhere

So now you know how different etiologies have different distributions on MRI.

Remember, catching a stroke on DWI isn’t the end of your job—it’s the beginning!

Cancer is the second and stroke is the fourth leading cause of death in the US. There is a connection between cancer, its treatments, and the vascular system, leading to an increased incidence of acute ischemic stroke in patients who harbor or were previously treated for an underlying malignancy.

This scientific statement incorporates multidisciplinary expertise, that has critically appraised and has synthesized recent evidence to provide clinical suggestions on the epidemiology, presentation, evaluation, pathophysiology, and treatments for ischemic stroke in patients with active cancer.

[AHA Science @AHAScience]

Brain imaging is essential to exclude hemorrhage in adult and pediatric patients eligible for AIS reperfusion therapies. Although CT-based protocols are more efficient and generalizable, MRI-based protocols may be appropriate in high-resource settings and in pediatric populations if similar time to imaging can be achieved as with CT.

ICE agents wouldn’t even allow a doctor to go check the pulse of the Renee Nicole Good whom they had shot in Minneapolis.

DOCTOR: Can I go check her pulse?”

ICE: NO!

DOCTOR: I’m A physician!

ICE: I Don’t Care!

These are the monsters of Trump‘s America.
