Cardiac Imaging

While cardiac ultrasound is the widely used imaging modality for heart assessments, computed tomography (CT), magnetic resonance imaging (MRI) and nuclear imaging are also used and are often complimentary, each offering specific details about the heart other modalities cannot. For this reason the clinical question being asked often determines the imaging test that will be used.

Collaborators from a number of international centers, led by the European Molecular Biology Laboratory-European Bioinformatics Institute, published their findings Wednesday in Nature. Using MRI scans, along with morphology and genetic data, they showed that this network of heart muscle fibers—known as the trabeculae—can influence the heart’s performance.

Thousands of MRI scans help experts understand 500-year-old heart mystery first described by Leonardo da Vinci

Artificial intelligence also played a large role in discovering how this intricate network of muscle fibers can influence health, experts explained in Nature.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
