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.

Gadolinium-enhanced MRI helps diagnose painful shoulder condition

Polymyalgia rheumatica is a musculoskeletal disorder that causes aching and stiffness in the upper arms, neck, lower back and thighs and can be difficult for clinicians to confidently pinpoint since its symptoms occur in many other rheumatic diseases.

3D neural network can help radiologists ID scarring associated with deadly heart condition

The boost in efficiency for measuring such scarring could make it easier for clinicians to overcome the time-consuming process of quantifying late gadolinium enhancement (LGE)—a proven predictor of hypertrophic cardiomyopathy.
