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.

The full force of AI will be felt with digital pathology

Artificial intelligence (AI) is sure to change radiology, but a recent feature in IEEE Spectrum argues its true effect on medicine will be felt not in imaging, but in the pathology lab.

New ghost imaging technique produces cheaper 3D x-rays, less radiation

Using a variation of an unconventional imaging approach called “ghost imaging," an international team of researchers has successfully taken low dose three-dimensional (3D) x-ray images which may help make screening for early signs of diseases and cancer cheaper, safer and more accessible.

Amazon releases AI language processing service for patient records, radiology reports

Tech company Amazon has launched a new medical language processing service that, by using artificial intelligence (AI), can extract data from patient records and reports to help healthcare professionals make better treatment decisions, address data privacy and decrease overall costs, according to a report published Nov. 28 by TechCrunch.

fMRI reveals video game addiction in men increases impulsivity

Using fMRI, researchers found that brain regions associated with impulsivity were altered in men who are addicted to video games, according to new findings presented Nov. 28 at RSNA 2018.

Novel imaging method measures iron minerals in the living brain

A novel imaging technology—magnetoencephalography (MEG)—allows scientists to measure levels of iron-based minerals in the brain, which may provide insight into neurodegenerative disorders such as Alzheimer’s disease, reported researchers from Massachusetts General Hospital (MGH) in Boston.
