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. 

A monarch is wowed by the wonders of modern medical imaging

The Queen of England and the Duke of Edinburgh have given two thumbs up to a new and sprawling neuroimaging center in Wales. 

Sheryl Crow named Hologic's national celebrity spokesperson for breast cancer educational campaign

Researchers image iron distribution in Alzheimer brains

An Australian chemist exploring the role of iron levels in Alzheimer’s disease has led an international effort to map these levels in deceased brains and compare them with iron levels in non-Alzheimer’s brains.

MRI may illuminate new avenues for schizophrenia treatment

Using MRI with covariance analysis, researchers have revealed tissue increases over time in the brains of patients with schizophrenia. The increases suggest these brains may be compensating for lost capacity and perhaps trying to protect themselves against further damage. 

FDA approves stand-alone 3D screening with Siemens Tomosynthesis Platform

Siemens Healthineers has received the approval of the FDA in the use of their Mammomat Inspiration with Tomosynthesis Option, the first and only digital mammography system to use a 3D digital breast tomosynthesis (DBT) platform as a stand-alone screening and diagnostic system.

Mother’s voice lights up child’s brain, and the connectivity predicts social skills

Children respond to their mothers’ voices differently than they respond to the voices of women they don’t know. That’s a no-brainer. But it’s something of a revelation to observe specific regions of a kid’s brain lighting up in fMRI when Mom speaks—and to find that the strength of connections between regions predicts how adept the child will become at social communication.

fMRI shows prayer beating back alcohol cravings in the brain

After looking at drinking-related images and then reciting prayers as part of a recent study, 20 long-sober members of Alcoholics Anonymous reported less craving for a drink than when they read irrelevant news or remained passive. Meanwhile, fMRI confirmed the effect, revealing participants’ brains lighting up most during the prayer interim. 

Survey: Severe stroke prognoses differ depending on the doctor

A survey of 742 physicians across the US found that after a intracerebral hemorrhage (ICH), doctors make varied recommendations and very different decisions regarding care.
