Summary: British researchers have developed an AI method for analyzing heart MRI scans that rapidly and accurately assesses heart function, potentially saving National Health Service time and resources while improving patient care through faster, non-invasive diagnostics.

Key Takeaways

  • Rapid MRI Analysis: The AI method developed by British researchers allows for the quick and accurate analysis of heart MRI scans, reducing the evaluation time from up to 45 minutes to just seconds, thereby significantly improving patient care and efficiency in the NHS.
  • Extensive MRI Data Training: The AI model was trained using MRI scan data from 814 patients across multiple hospitals, ensuring robust and reliable performance when analyzing heart function, and it was further validated with data from an additional 101 patients.
  • Comprehensive MRI-Based Heart Analysis: Unlike previous studies focusing on two heart chambers, this AI model provides a complete analysis of all four chambers using MRI scans, offering more detailed and consistent assessments that could revolutionize cardiac diagnostics and treatment planning.

British researchers have developed a groundbreaking AI method for analyzing heart MRI scans, potentially saving National Health Service time and resources while improving patient care. Teams from the Universities of East Anglia (UEA), Sheffield, and Leeds in England created an AI model to examine heart images from MRI scans in the four-chamber plane.

Pankaj Garg, MD, PhD, from UEA’s Norwich Medical School and a consultant cardiologist, leads the team pioneering innovative 4D MRI imaging technology for faster, non-invasive, and accurate diagnosis of heart conditions. “The AI model quickly and accurately determines the size and function of the heart’s chambers, comparable to manual methods but much faster,” Garg says. “Unlike the standard manual analysis taking up to 45 minutes, the AI model works in seconds, offering speedy, reliable heart health evaluations to enhance patient care.”

The retrospective study used data from 814 patients at Sheffield and Leeds hospitals to train the AI model, and from another 101 patients at Norfolk and Norwich University Hospitals for testing.

While previous studies have explored AI in MRI scans, this model was trained with data from multiple hospitals and scanners, and tested on a diverse patient group, providing a complete heart analysis using the four-chamber view, unlike earlier studies focused on just two chambers.

UEA PhD student Hosamadin Assadi notes: “Automating heart function and structure assessments saves time, ensures consistency, and could lead to more efficient diagnoses, better treatments, and improved patient outcomes. AI’s potential to predict mortality based on heart measurements could revolutionize cardiac care.”

Researchers suggest future studies should test the model with larger, more diverse patient groups and various MRI scanners to validate its effectiveness in broader real-world scenarios.

Recent research by the same teams has refined heart MRI scan methods for female patients, increasing diagnoses by 16.5% for those with early or borderline heart disease.
