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.

Deep learning rivals fellowship-trained radiologists at segmenting breast cancers on MRI

Researchers trained their platforms on more than 60,000 individual breast scans, significantly more than most architectures.

Staged cyberattack altering mammography images deceives both AI and radiologists

If artificial intelligence software makes a false prediction it can lead to harmful consequences for patients, providers and insurers, experts from the University of Pittsburgh cautioned.

Stand-alone AI can reduce radiologists’ screening mammography workloads by 90%

The technique may also prove cost-effective if radiologists are free to only focus on AI-recalled findings.

New hope for ‘mechanically dynamic’ tissue that’s been damaged

Mechanical engineers have developed injectable hydrogels that can fuse with frequently moving tissues—like those of the heart, muscles and vocal cords—to repair damage and restore function.
