Using AI to Predict Strokes

by | Mar 25, 2021 | AI, FDA, Medical Devices, ML, Quality

One of the major purposes manufacturers incorporate AI or ML in their applications is to ease software computations and to predict precise results. I think compared to any other application, a medical application requires a lot of precise computations and therefore, AI is a perfect solution to enhance performance and productivity. While reading the health-tech news, I came across recent research in this regard, the use of AI in predicting a potential stroke or cardiac arrest.

This study was published in February 2020 in Circulation, The American Heart Association Journal. The major component used in this research work is cardiovascular magnetic resonance (CMR) imaging along with a contrast agent. Scanned CMRs provide the quantitative measure of the blood flow to the heart and a contrast agent is a substance that distinctively identifies certain elements during the standard imaging process. The lower the quantitative value of the CMR (pure blood flow), the higher the risk of having a stroke. Presumed to be one of the largest studies of its kind, the AI model was ‘learned’ or trained using CMRs of more than 1000 patients. Following my research, I found that the AI model utilized was Deep Convolutional Neural Network (DCNN).1 DCNNs are indeed the preferred AI model when it comes to image training, testing, and prediction. Once the model was trained and ready, new patient input data was supplied for checking the live predictive output. This input data was constituted by new CMRs along with other health parameters such as age, gender, weight, lifestyle habits, and other existing chronic diseases.2

Using the learned training data, the DCNN model predicted if there are signs of a potential stroke or cardiac arrest for patients of whom new CMRs were supplied for testing. With such predictions, patients can start early treatment and change their lifestyle habits to reduce or even eliminate the chance of a stroke.  This is a monumental achievement for healthcare providers and patients alike.

To summarize, researchers in the healthcare sector are employing AI for predicting the probability of a stroke. But before the software is deployed and installed, manufacturers should ensure that their product is thoroughly validated. EMMA International has experience validating complex software applications that include AI, Cloud, IoT, and Cybersecurity. Also, our experienced quality and software experts can guide you through the FDA regulatory process to ensure your AI/ML-based medical device is FDA compliant.

Process Validation

All right, you have just gotten all of your paperwork together, submitted the right forms to the right people, set up your factory, hired and trained your staff; now it’s time to make the medical devices. The regulatory nonsense is over and done, right?
The Role of Management in Product Quality

The Role of Management in Product Quality

Depending on the factory, some production employees may find it surprising that management has an important role to play in a quality system.  21 CFR 820.20 mandates that “Management with executive responsibility shall establish objectives for, and commitment to, quality”.[1]  The Federal Government expects that management takes an active interest in improving the output of their company, at least in the case of medical device manufacturers.

Corrective and Preventive Action

In addition to helping manufacturers make better products, corrective and preventive actions are important because the process is legally required by the FDA when making medical devices for the US market.
