1/Welcome to our first OCT #Tweetorial! We'll cover a few key
concepts and share a step-by-step guide on the basics of image
interpretation 🤓 #imagefirst #OCTimaging

2/First things first, what is OCT?

OCT stands for optical coherence tomography which is an imaging modality that uses near-infrared light to provide high definition images of the artery.

4/Here's a view of normal vessel tissue. Media appears as a slightly darker band between the other two layers ("tire" looking dark line).

5/OCT helps to identify different microstructures, tissue and plaque

Here are the three most common types:

6/Here’s one way to remember visualization of most common plaque with OCT:

Fibrotic plaque = full of light
Lipid plaque = absence of light
Calcified plaque = a border can be drawn around it

7/To describe images, we use "attenuation" in regards to light penetration, or
simply "loss of light"
(A) High attenuation=high loss of light, dark image, can't see deep tissue
(B) Low attenuation=light penetrates deep, can see tissue

8/ To help you interpret OCT images, check out this cool algorithm developed by @ZiadAlinyc.

Simply put: can you see the EEL? And what do the lumen and vessel wall look
