Comprehensive CCTA Analysis

Spimed-AI built a radiology innovation based on an artificial intelligence that automatically classifies coronary lesions from CT scans
Our Story

Dr JF Paul is a radiologist and researcher at the Institut Mutualiste Montsouris with more than 20 years
experience and 110 publications on cardiac imaging to his credit. Thanks to partnership with the Institut Mutualiste Montsouris, he was able to launch the CorEx project to apply AI to coronary disease.

Our Vision

Cardiovascular diseases are the first cause of death in the world. According to the WHO, they are responsible for 17.7 millions death worldwide each year.

To tackle the issue, the coronary CTA is the reference exam (Nice guidelines). That’s why Spimed-AI developed CorEx. With CorEx, only one exam is needed and is used at its highest potential.


The CorEx project started in 2017, building a large annotated database of 10,000 coronary CT images, allowing an automatic anatomical and functional analysis

of coronary scanner images by Artificial Intelligence.

How it works

The solution automatically classifies stenosis according to the international CAD-RADS classification. With CorEx, you can see in seconds which artery is damaged and the severity of the obstruction.


For research use only

An attenuation of more than 80% of the blood flow through the stenosis is the common threshold to consider the stenosis as significant and dangerous. Beyond this point, surgery is recommended. The most common procedures are the stent and the bypass.

For each coronary, the solution predicts if this important threshold is reached or not.

"29,4% of the patients addressed for coronary CT angiography didn’t have pre-test that could have been effective and non invasive."
