By Bibb Allen, Jr., MD, FACR, ACR DSI Chief Medical Officer | Diagnostic Radiologist, Grandview Medical Center, Birmingham, AL | April 04, 2019

Empowering radiologists to develop AI algorithms at their own institutions, using their own patient data, to meet their own clinical needs, could potentially accelerate the development of AI for diagnostic radiology.Currently, developments in AI for the radiological sciences are being driven by exciting research happening primarily at institutions with extensive informatics and data science resources — and primarily using single institution patient data. While some of these algorithms are achieving performance levels similar to the performance of diagnostic radiologists, it is not clear if and how these tools will be generalized to widespread clinical use across multiple institutions. Without that transition, AI will fail to have broad impact on patient care.

Artificial Intelligence is Everywhere

AI has crept into all aspects of our lives, and the same will be true for radiology.

By Andy DeLaO | Patient Advocate | March 20, 2018

I feel a vibration on my wrist that gently wakes me from my sleep. I roll over, touch the device on my wrist, and lay there for about five more minutes. Then I feel another vibration. I check the time on my phone. It’s 5:30 — time to get up.

My morning ritual starts in earnest: I weigh myself on my digital scale, which shows that my weight is the same as the previous day and automatically syncs with my wearable fitness tracker. As I get dressed, I ask Alexa, a voice-controlled speaker and personal assistant, to play Lose Control by Missy Elliott.

Radiologists must learn the language of AI to make a successful payment policy case.

By Ezequiel Silva III, MD, FACR | Physician | January 23, 2018

Learning the Language of AI

Artificial intelligence (AI) has its own language. So does economics. I feel pretty confident with econ-speak and can throw out phrases like intensity of work or acronyms like CPT, HOPPS, and QPP in rapid fire. But I am not as well-versed in the language of AI — a point that became apparent during a recent “Economics of AI” talk I gave to a room full of radiology AI experts.
