2/Let's use this french fry illustration I used for my varices🧵
I use the curve function to create shapes. It has the most control for drawing--the freeform function causes uneven lines.
After drawing the shape, I use the shape fill function to fill it in it w/the color I need
3/ 3D effects begin w/the gradient fill. I use the gradient fill that powerpoint offers for my selected color--it knows how to chose them so that the gradient is smooth
4/ Now to get more advanced w/focal shadows. Using the curve function, I draw shapes where I want shadows. Then I fill these in using the eyedropper function on the Shape Fill menu. I touch the eyedropper to the darkest part of the gradient to fill them in w/a nice dark shadow.
5/ Now these shapes need to be blurred so they look more like shadows. I select them and go to the "Shape Effects" menu & select "Soft Edges." I⬆️the size of the soft edge until they look like good shadows. It is different for every shape, but usually you need at least 5 point
6/Now for highlights. I use the curve function to draw shapes where I want highlights. Similar to shadows, I use the eyedropper function to fill in the shapes--but instead of putting the eyedropper on the darkest part of the gradient, I put it in the lightest part of the gradient
7/However, for highlights, the lightest part of the gradient isn't light enough. So I select the shape, go to shape fill color & select "More colors." This brings up a box where you can lighten the shade of that color--the same way light would lighten it if it was shining on it.
8/Now it is time to blur these highlights the same way we blurred the shadows--using the soft edges function, increasing the soft edge until you get desired look of your highlight.
9/Now we add details. First, I drew the McDonalds logo using the curve function. Then I used the curve function to draw a single fry. I took that fry & copied & pasted it over &over again--each time rotating it & stretching it to make it look like there were many different fries
10/Voila! That is how you make a very professional illustration using only PPT & in only a few easy steps! Excited to see what you will create w/these new skills!
I post more of my tips for creating these illustrations in PPT--so if interested click to follow me @teachplaygrub

1/ I always say, "Anyone can see the bright spot on diffusion images—what sets you apart is if you can tell them why it’s there!”
If you don't why a stroke happened, you can't prevent the next one!
Can YOU tell a stroke’s etiology from an MRI?
Here’s a thread to show you how!
2/First a review of the vascular territories.
I think the vascular territories look a butterfly—w/the ACA as the head/body, PCA as the butt/tail, and MCA territories spreading out like a butterfly wings.
3/Of course, it’s more complicated than that.
Medially, there are also small vessel territories—the lenticulostriates & anterior choroidal.
I think they look like little legs, coming out from between the ACA body & PCA tail.
1/Asking “How old are you?” can be dicey—both in real life & on MRI!
Do you know how to tell the age of blood on MRI?
Here’s a thread on how to date blood on MRI!
After reading this, when you see a hemorrhage, your guess on its age will always be in the right vein!
2/If you ask someone how to date blood on MRI, they’ll spit out a crazy mnemonic about babies that tells you what signal blood should be on T1 & T2 imaging by age.
But mnemonics are crutch—they help you memorize, but not understand
If you understand, you don’t need to memorize
3/If you look at the mnemonic, you will notice one thing—the T1 signal is all you need to tell if blood is acute, subacute or chronic.
T2 signal will tell if it is early or late in each of those time periods—but that type of detail isn’t needed in real life
@TheAJNR 2/Since the prehistoric days of medicine (1979!), we knew that some brain tumor patients treated w/radiation (XRT) initially declined, but then get better.
Today, we see this on imaging, where it looks worse early, but then gets better.
Now we call this pseudoprogression.
@TheAJNR 3/Why does this happen?
XRT induces a lot of inflammatory changes—from initiating the complement cascade to opening the blood brain barrier (BBB)
It’s these inflammatory changes that make the imaging look worse.
