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!

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.
If you don’t know the time of stroke onset, are you able to deduce it from imaging?
Here’s a thread to help you date a stroke on MRI!
2/Strokes evolve, or grow old, the same way people evolve or grow old.
The appearance of stroke on imaging mirrors the life stages of a person—you just have to change days for a stroke into years for a person
So 15 day old stroke has features of a 15 year old person, etc.
3/Initially (less than 4-6 hrs), the only finding is restriction (brightness) on diffusion imaging (DWI).
You can remember this bc in the first few months, a baby does nothing but be swaddled or restricted. So early/newly born stroke is like a baby, only restricted
1/”I LOVE spinal cord syndromes!” is a phrase that has NEVER, EVER been said by anyone.
Do you become paralyzed when you see cord signal abnormality?
Never fear—here is a thread on all the incomplete spinal cord syndromes to get you moving again!
2/Spinal cord anatomy can be complex. On imaging, we can see the ant & post nerve roots. We can also see the gray & white matter. Hidden w/in the white matter, however, are numerous efferent & afferent tracts—enough to make your head spin.
3/Lucky for you, for the incomplete cord syndromes, all you need to know is gray matter & 3 main tracts. Anterolaterally, spinothalamic tract (pain & temp). Posteriorly, dorsal columns (vibration, proprioception, & light touch), & next to it, corticospinal tracts—providing motor
