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.

Study finds roasted barley a superior contrast agent for imaging swallowing disorders

When researchers bought more than 200 types of tea, chocolate, herbs and other items they weren’t planning meals for the week. Instead, the team was searching for a contrast agent for imaging patients with swallowing disorders—they landed on barley.

Florescence, microscopic imaging may expand view of cellular processes inside tumors

European researchers have developed a robust macroscale imaging technique based on florescence lifetime imaging microscopy (FLIM) that can analyze cellular processes up to four centimeters in size.

High-resolution image may be key to treating Zika virus

Researchers have captured the highest-resolution image to date of the Zika virus, which caused a global health crisis in 2015, and left thousands of babies with serious birth defects. The research team believes the finding may aid in designing a vaccine to fight the virus.
