AI can find, classify pleural effusions on chest x-rays
May 18, 2018 -- An artificial intelligence (AI) algorithm has shown promising results for finding and classifying pleural effusion on chest x-ray studies, potentially helping to speed up interpretation times and triage priority cases.  Discuss
MITA hails FDA quality report, seeks legislative action
May 16, 2018 -- The Medical Imaging and Technology Alliance (MITA) said it strongly supports a new initiative by the U.S. Food and Drug Administration (FDA) to promote the adoption of quality management principles in equipment servicing; however, the group is also calling on Congress to take legislative action to protect patient safety.  Discuss
Can ultrasound screen for fetal growth restriction?
May 15, 2018 -- Can second-trimester ultrasound screening for fetal growth restriction reliably predict if a baby will go on to have a low birth weight for his or her gestational age? Not in most cases, according to recent research from Vanderbilt University Medical Center in Nashville, TN.  Discuss
Will AI cause radiologists to go the way of horses?
May 14, 2018 -- Will radiologists meet the same fate from the advent of artificial intelligence (AI) as horses following the development of machine power? It's possible, according to an opinion article published online May 11 in the Journal of the American College of Radiology.  Discuss
How will AI impact image interpretation process?
May 9, 2018 -- Will artificial intelligence (AI) lead radiologists to begin overcalling potential abnormalities during image interpretation? Not necessarily, if a recent study that assessed the impact of computer-aided detection software on patient recall rates in screening mammography is any indication.  Discuss
New framework facilitates radiology AI algorithms
May 9, 2018 -- How can artificial intelligence (AI) algorithms best be developed and implemented in radiology? A new framework created by the American College of Radiology's Data Science Institute will show the way, according to an article published online May 5 in the Journal of the American College of Radiology.  Discuss
AI can prescreen chest CT studies for pneumothorax
May 7, 2018 -- An artificial intelligence (AI) algorithm can be highly sensitive for detecting pneumothorax on chest CT images, potentially enabling radiologists to quickly prioritize these life-threatening cases for priority review, according to research from Massachusetts General Hospital and Harvard Medical School.  Discuss
Automated breast density assessment informs cancer risk
May 1, 2018 -- Can software that calculates breast density perform as well as a radiologist and help identify a woman's future risk of breast cancer -- in particular, the risk of invasive interval cancers? Yes, it can, according to research published May 1 in the Annals of Internal Medicine.  Discuss
CMS proposes overhaul of meaningful use program
April 25, 2018 -- The U.S. Centers for Medicare and Medicaid Services (CMS) has proposed a number of changes to its Inpatient Prospective Payment System and the Long-Term Care Hospital Prospective Payment System for 2019, including renaming and overhauling its meaningful use IT stimulus program.  Discuss
Will ultrasound and AI become the tricorder of the future?
April 19, 2018 -- Artificial intelligence (AI) will soon bring many benefits to point-of-care ultrasound (POCUS), and perhaps one day it will enable these systems to fulfill the promise of the legendary tricorder from "Star Trek." But it could also lower the bar in terms of who is able to read POCUS scans -- potentially threatening physicians.  Discuss
