A new policy from the US National Institutes of Health (NIH) will end billions of dollars of funding to laboratories and hospitals outside the United States, imperiling thousands of projects on topics such as emerging infectious diseases and cancer.

Time is brain!

So you don’t have time to struggle w/that stroke alert head CT.

Here’s are the FIVE main the CT findings in acute stroke.

--Hyperdense artery sign
Occurs when you see the thrombus in the artery.
Thrombus appears hyperdense bc clot is denser than normal flowing blood—& CT is just a measure of density.

--Blurred basal ganglia/lentiform nucleus.
Usually this region is a triangle of low density white matter surrounding the high density lentiform nucleus
In an acute infarct, this triangle becomes blurred, bc the lentiform nucleus becomes edematous & similar in density to white matter.

--Hypodense regions of brain
When O2 & ATP run out, Na/K pump stops working
Osmotic gradient causes Na & H20 rush into the cell.
More water in the cell = lower density.  For every 1% increase in H20 there is a 2.5 HU decrease in density
Means damage is irreversible

--Insular ribbon
Insula is an internal MCA watershed between the lenticulostriates & M2 sylvian branches
Infarcts relatively early with low blood supply & becomes a low density ribbon

--Sulcal effacement
Normally, brain has sulci that look like ice cracks/crevasses along its surface.
As water accumulates in dead cells, swelling occurs, & the crevasses are effaced by the swollen brain

So now you know the 5 main signs of acute infarct on CT—remember, if you see these five, soon that brain won’t be alive!

New study looking at mild tICHs (GCS 14-15) on Xa's and reversing (w/ 4PCC) vs not. No difference in hemorrhage progression or neuro outcomes btwn groups (some baseline diff in ISS)

I'll be discussing prior lit @EMPRx24 on this controversial topic
