1/You don't need fancy programs to make great #Illustrations!
#Powerpoint is actually an extremely powerful illustrating tool--if you know the secret #hacks!
Here is a đź§µof videos explaining my best tips & tricks so you can make your own great figures, all just w/powerpoint!
2/First, how to make a great 3D vessel in just 3 steps!
The video below shows you that all you need is a gradient, an edge shadow, and an inner glow to make an amorphous curve into a great figure of a vessel:
3/Next, how to get a metallic sheen.
To make metal look real & 3D, you need that bright line of metallic reflection.
The video below shows you how to make a bland colored object reflect light like it's pure gold, just using simple gradients:
4/And of course, one of PPT's most powerful drawing functions isn't even known by most people--the inner shadow function!
It makes figures of humans/bodies look more 3D.
The video below shows how to add 3D shadows right where you need it automatically
5/I am working on making more videos on my powerpoint drawing tips, tricks, & hacks. So keep following for more!
Remember, you don't need expensive programs to make amazing figures for your presentation. You just need powerpoint, some quick tricks, and your own imagination!

Brain MRI anatomy is best understood in terms of both form & function.
Here’s a short thread to help you to remember important functional brain anatomy--so you truly can clinically correlate!
2/Let’s start at the top. At the vertex is the superior frontal gyrus. This is easy to remember, bc it’s at the top—and being at the top is superior. It’s like the superior king at the top of the vertex.
3/It is also easy to recognize on imaging. It looks like a big thumb pointing straight up out of the brain. I always look for that thumbs up when I am looking for the superior frontal gyrus (SFG)
@TheAJNR 2/Everyone knows about the spot sign for intracranial hemorrhage
It’s when arterial contrast is seen within a hematoma on CTA, indicating active
extravasation of contrast into the hematoma.
But what if you want to know before the CTA?
@TheAJNR 3/Turns out there are non-contrast head CT signs that a hematoma may expand that perform similarly to the spot sign—and together can be very accurate.
1/My hardest thread yet! Are you up for the challenge?
How stroke perfusion imaging works!
Ever wonder why it’s Tmax & not Tmin?
Do you not question & let RAPID read the perfusion for you? Not anymore!
2/Perfusion imaging is based on one principle: When you inject CT or MR intravenous contrast, the contrast flows w/blood & so contrast can be a surrogate marker for blood.
This is key, b/c we can track contrast—it changes CT density or MR signal so we can see where it goes.
3/So if we can track how contrast gets to the tissue (by changes in CT density or MR signal), then we can approximate how BLOOD is getting to the tissue.
And how much blood is getting to the tissue is what perfusion imaging is all about.
