Will #AI enhance care of patients?
Yes!
How?
-Improved reliability
-Atherosclerosis guided Rx
-Risk prediction
-Requires validation ✅

Proud to share my #SCCT2021 talk (1/5)
AI & ML in #YesCCT: New Frontiers in Atherosclerosis

AI & ML in #YesCCT: New Frontiers in Atherosclerosis

-The field of #YesCCT has evolved rapidly
-Current CV risk prediction models are inadequate – can AI help?
-Average imager may read > 1 billion pixels per day
#SCCT2021 (3/5)
#AI & ML in #YesCCT: Atherosclerosis

-Be mindful of caveats, ensure validity & avoid hype
-Opportunity to improve #CCT reproducibility (in conjunction w/ education!)
-#CLARIFY - algorithm validation
-#CLARIFY– high accuracy for %stenosis

@mirvatalasnag
#AI/ML in #YesCCT: Atherosclerosis #SCCT2021 (4/5)

-Comprehensive evaluation of atherosclerosis that is challenging, even for expert readers!
-Plaque allows us to understand the spectrum of atherosclerotic risk
-Low stenosis patient may have high plaque volume!

@mirvatalasnag
#AI & #ML in #YesCCT: Atherosclerosis #SCCT2021 (5/5)

-New future paradigm of AI guided prevention is emerging
-Opportunities to study disease progression
-Potential to better understand Rx non-response
-Ensure rigor-#PRIME
-The future is here!

Great session on Artificial Intelligence and Machine learning with session chairs @imagingmedsci, Dr. Bratt, @michael_t_lu, @ivanaisgum, Dr. Al'Aref and @DeCeccoCN at #SCCT2021!

#ICYMI - Here's a brief tweetorial from the #YesCCT session (1/7)
@mirvatalasnag @HeartOTXHeartMD
#AI & ML in #YesCCT: #SCCT2021 #Tweetorial (2/7)
1⃣: The big picture & black box by Dr. Michael Lu
-Multiple “black box” definitions
-Explainability
-Predictability
-More accurate than SOC, visualizes output (& modifiable), communicates uncertainty (eg grey-zone FFR-CT)
3⃣#AI & ML in #YesCCT #SCCT2021: New frontiers in atherosclerosis @AChoiHeart

-Use of #CNN for whole heart stenosis & atherosclerosis
-Improved reproducibility of stenosis to enhance guideline adherence
-Individualized risk prediction
-New Rx paradigm!
