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.

PET scans reveal women’s brains appear 3 years younger than men’s

With the help of PET scans, researchers have found women’s brains appear to be three years younger than men’s. The findings, published in Proceedings of the National Academy of Sciences, may explain why women tend to remain mentally sharper longer than men.
