Artificial Intelligence

Artificial intelligence (AI) is becoming a crucial component of healthcare to help augment physicians and make them more efficient. In medical imaging, it is helping radiologists more efficiently manage PACS worklists, enable structured reporting, auto detect injuries and diseases, and to pull in relevant prior exams and patient data. In cardiology, AI is helping automate tasks and measurements on imaging and in reporting systems, guides novice echo users to improve imaging and accuracy, and can risk stratify patients. AI includes deep learning algorithms, machine learning, computer-aided detection (CAD) systems, and convolutional neural networks.

Can MR images of dogs offer insights into human brains?

Why do some dogs hunt while others herd? The connection between brain structure and function is well-known in both humans and canines, but new research published in the Journal Neuroscience offers new insight into the relationship between innate brain wiring and learned behavior.

AI built on CCTA images can predict heart attacks

Researchers from the University of Oxford have created a new biomarker based off of coronary CT angiography (CCTA) images that can select patients at a high risk of heart attack five years before they occur.

AI chatbots have a future in healthcare, with caveats

Healthcare consumers are open to interacting with AI chatbots as long as the interaction involves general health information, not patient-specific advice or results from exams.

3D MRI measures heart muscle strain without gadolinium

A new three-dimensional (3D) MRI technique can measure strain in the heart without using potentially-damaging gadolinium, according to new research out of the University of Warwick in the U.K.
