Lung ultrasound beats chest x-ray for heart failure detection
March 15, 2019 -- Point-of-care lung ultrasound has a higher sensitivity than chest x-ray for detecting symptoms of pulmonary edema in patients with acute decompensated heart failure, according to a new meta-analysis. The findings could indicate that ultrasound is a better choice for these patients, according to a study published March 15 in JAMA Network Open.  Discuss
Accuracy of AI algorithms may drop with independent data
March 13, 2019 -- The performance of artificial intelligence (AI) algorithms for classifying chest x-rays dropped when they were used with patient populations that were different from the ones on which they were trained, according to research published online March 5 in the Journal of Digital Imaging.  Discuss

January 31, 2019 -- An artificial intelligence (AI) algorithm can both detect and show the position of fractures on wrist radiographs with a high level of sensitivity and specificity, according to research published online January 30 in the inaugural issue of the RSNA's new Radiology: Artificial Intelligence journal.  Discuss
Stanford launches huge dataset of chest x-rays for AI
January 25, 2019 -- Researchers from Stanford University have released a massive dataset of more than 224,000 chest x-rays to be used for the development of artificial intelligence (AI) algorithms. The group has also launched a competition for developers of AI algorithms to test their models.  Discuss
AI can identify, triage abnormal chest x-rays
January 23, 2019 -- An artificial intelligence (AI) algorithm was able to accurately identify chest radiographs that contain abnormal findings, enabling automated triage of these exams so they can be interpreted sooner by radiologists, U.K. researchers reported in a study published online January 22 in Radiology.  Discuss
