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.

Upcoming radiology podcast challenges imaging experts to step up and question the negative AI hype

In an exclusive conversation with HealthImaging, John D. Banja, a professor of medical ethics at Emory University, discusses plans to launch a series of audio chats with radiologists, exploring one of the profession's stickiest issues.

Penn researchers want to know how opioids affect brain development via neuroimaging

A pair of Penn researchers will scan 100 awake 3-5 year old children, comparing the quality of traditional MRI methods to those taken using a motion-correction technology to better understand the connection between opioids and brain development.

Gadolinium-enhanced MRI helps diagnose painful shoulder condition

Polymyalgia rheumatica is a musculoskeletal disorder that causes aching and stiffness in the upper arms, neck, lower back and thighs and can be difficult for clinicians to confidently pinpoint since its symptoms occur in many other rheumatic diseases.

Around the web

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
