Researchers have created a new AI based image analysis that uses optical coherence tomography (OCT) pictures to detect plaque erosion in arteries of the heart.

Plaque erosion in arteries should be monitored because if it breaks apart, it can impede blood flow to the heart, resulting in a heart attack or other dangerous diseases.

Acute coronary syndrome occurs when cholesterol plaques lining the arteries begin to disintegrate, resulting in an abrupt reduction in blood flow to the heart and necessitating immediate treatment.

Our innovative technology could aid in the clinical diagnosis of plaque erosion and the development of new medicines for heart disease patients.

What is Optical Coherence Tomography Used For

OCT is a micron-scale optical imaging technology that, when combined with a tiny catheter, can be used in blood vessels to obtain 3D images of the coronary arteries that supply blood to the heart.

Despite the fact that doctors are increasingly adopting intravascular OCT to look for plaque erosion, the enormous amount of data generated and the complexity of visual interpretation of the pictures has resulted in high interobserver variability.

To address this issue, develop an objective, automatic method based on OCT scans that uses AI to detect plaque and detect erosion. In the publication, discussing about novel technique and show that it is accurate enough to be used as a basis for clinical diagnosis.

“Without any further input, a new AI-based method can automatically detect the presence of plaque erosion using the original OCT pictures,”. “The capacity to detect plaque degradation objectively and automatically will lessen the time-consuming manual assessment required for diagnosis.”

Apply AI Based Image Analysis

There are two primary steps in the new technique. To begin, an AI model known as a neural network is used to predict areas of possible plaque erosion using the original image and two bits of shape information.

A post-processing technique based on clinically interpretable features refines the initial prediction, simulating the knowledge professional physicians need to establish a diagnosis.

“Needed to create a new AI model that included explicit shape information, which is a vital characteristic for detecting plaque degradation in OCT pictures,”.

“The underlying intravascular OCT imaging technology is extremely important because it is currently the highest resolution imaging modality available for diagnosing plaque erosion in living patients.”

The imaging probe is automatically pushed back into a catheter when OCT is used for intravascular imaging, producing hundreds of images per each retraction.

The researchers used 16 pullbacks of 5,553 clinical OCT pictures with plaque erosion and 10 pullbacks of 3,224 images without plaque erosion to test their approach.

With a positive predictive value of 73 percent, the automated technique correctly predicted 80 percent of plaque erosion cases. They also discovered that the automated method’s diagnosis closely matched those of three expert physicians.

While more safety testing and regulatory permission are needed before the approach can be used in patients on its own, believes it might be used to help diagnose plaque erosion.

“Physicians do a last check on the algorithm’s findings before establishing the cause of acute coronary syndrome and the appropriate therapy options.”

Studying New Treatments

By avoiding the time-consuming and difficult process of manual image processing, the approach can also be used to analyze enormous amounts of existing OCT data.

This could aid scientists in better identifying and treating plaque erosion. A stent, for example, is commonly used to restore decreased blood flow in patients with acute coronary syndrome, but new research suggests that some medications may provide a less intrusive alternative.

“Intravascular imaging combined with AI technology can be a very useful tool for diagnosing and treating coronary artery disease,” .

“In the future, this innovative technique could aid clinicians in developing tailored therapy regimens for the best management of patients with acute coronary syndrome,”.

To increase the effectiveness of the AI model, the researchers are currently aiming to improve their new technique by better incorporating 3D information and including more unlabeled data.

They also intend to train and assess the system using a larger dataset with a global population in the future.

They also want to see how it could be utilized in different therapeutic scenarios to show how effective and valuable it could be.


Using intravascular OCT images, a new approach makes it easier to detect plaque degradation.

what is optical coherence tomography used for? Using optical coherence tomography (OCT) pictures, researchers have created a new artificial intelligence (AI) technology that can automatically detect plaque erosion in arteries. Plaque in the arteries should be monitored because when it breaks up, it can impede blood flow to the heart, resulting in a heart attack or other dangerous diseases.

People May Ask 3

Q- What is the purpose of an OCT test?

A- Optical coherence tomography (OCT) is a noninvasive imaging technique that creates images of the back of your eye using reflected light. Diabetic retinopathy and glaucoma are two disorders that can be diagnosed and managed using it.

Q- What is picture analysis based on artificial intelligence (AI)?

A- The process of identifying certain attributes of specific objects in an image is known as image recognition. Object detection, object recognition, and segmentation are common approaches used in AI-based picture recognition.

Q- What is plaque erosion and how does it happen?

A- An acute thrombus in direct contact with the intima in a denuded endothelium area is characterized as plaque erosion. As a result of an intimal fibroatheroma in the coronary artery wall being prone to erosion or rupture, plaque events occur.

Q- What is plaque and how does it affect your arteries?

A- Fatty compounds, cholesterol, cellular waste materials, calcium, and fibrin are all found in plaque. The artery walls thicken and stiffen when it builds up in the arteries. Atherosclerosis is a chronic, slow-moving illness that can begin in childhood. It can, however, move quickly.

Q- What causes artery plaque formation?

A- When cholesterol sticks to the inside of an artery’s wall, plaque forms. To combat the cholesterol, the body sends white blood cells to catch it, which then convert into foamy cells that spew more fat and produce more inflammation. Muscle cells in the artery wall grow as a result, forming a cap over the affected area.
