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/Need help reading spine imaging? I’ve got your back!
It’s as easy as ABC!
A thread about an easy mnemonic you can use on every single spine study you see to increase your speed & make sure you never miss a thing!
2/A is for alignment
Look for: (1) Unstable injuries
(2) Malalignment that causes early degenerative change. Abnormal motion causes spinal elements to abnormally move against each other, like grinding teeth wears down teeth—this wears down the spine
3/B is for bones.
On CT, the most important thing to look for w/bones is fractures. You may see focal bony lesions, but you may not
On MR, it is the opposite—you can see marrow lesions easily but you may or may not see edema associated w/fractures if the fracture is subtle
@TheAJNR 2/Vascular cognitive impairment, or its most serious form, vascular dementia, used to be called multi-infarct dementia.
It was thought dementia directly resulted from brain volume loss from infarcts, w/the thought that 50-100cc of infarcted related volume loss caused dementia
@TheAJNR 3/But that’s now outdated. We now know vascular dementia results from diverse pathologies that all share a common vascular origin.
It’s possible to lose little volume from infarct & still result in dementia.
So if infarcts are common—which contribute to vascular dementia?
@TheAJNR 2/In the lumbar spine, it is all about the degree of canal narrowing & room for nerve roots.
In the cervical spine, we have another factor to think about—the cord.
Cord integrity is key. No matter the degree of stenosis, if the cord isn’t happy, the patient won’t be either
@TheAJNR 3/Cord flattening, even w/o canal stenosis, can cause myelopathy.
No one is quite sure why.
Some say it’s b/c mass effect on static imaging may be much worse dynamically, some say repetitive microtrauma, & some say micro-ischemia from compression of perforators
