CAD of chest tomosynthesis works best for new readers
December 26, 2017 -- Computer-aided detection (CAD) of digital chest tomosynthesis studies helped improve the diagnostic performance of inexperienced readers in a study by Japanese researchers published December 13 in Radiology. But CAD's effect was not statistically significant with physicians who had more experience.  Discuss
Quantitative analysis may help classify thyroid nodules
December 22, 2017 -- The echogenicity of solid thyroid nodules is often assessed qualitatively during evaluation on ultrasound. But this task can also be performed quantitatively, potentially offering a useful tool for determining malignancy risk, according to research presented at the RSNA 2017 meeting in Chicago.  Discuss
Deep learning analyzes PET for signs of dementia
December 22, 2017 -- A deep-learning algorithm that analyzed FDG-PET was able to differentiate between normal cognition and dementia. Such models could someday help radiologists diagnose Alzheimer's disease, especially if they don't see the condition often, according to a study presented at the RSNA 2017 meeting.  Discuss
How often are lung nodules missed on CAC scoring scans?
December 21, 2017 -- If an incidental lung nodule is present on a CT coronary artery calcium (CAC) scoring scan, how often is that nodule actually detected and worked up? Not as often as one might expect, according to researchers who analyzed the reasons why nodules might be missed in a presentation at RSNA 2017.  Discuss
How 2018 coding changes will affect radiology practices
December 21, 2017 -- Are you ready for new revisions to current procedural terminology (CPT) codes set to take effect in the Medicare system in 2018? Rebecca Farrington of Healthcare Administrative Partners helps you get up to speed in this new article.  Discuss
JACR: Rads want more help with point-of-care ultrasound
December 21, 2017 -- Radiologists would like more support from the American College of Radiology (ACR) for point-of-care ultrasound, according to an analysis of data from the ACR's 2017 workforce survey published December 19 in the Journal of the American College of Radiology.  Discuss
US improves success rate of pediatric artery cannulation
December 20, 2017 -- Ultrasound-guided radial artery cannulation in children is twice as successful as the traditional technique that has long been used to place cannulas, involving palpation of a patient's radial pulse, according to research published in the December issue of the Journal of Ultrasound in Medicine.  Discuss
AI can spot large pneumothoraces on chest x-ray
December 20, 2017 -- Artificial intelligence (AI) algorithms can automatically detect large pneumothoraces on chest x-ray exams -- potentially speeding up the detection and reporting of these critical findings, according to research presented at the RSNA 2017 meeting in Chicago.  Discuss
FDA issues directive on GBCA labeling, safety research
December 19, 2017 -- The U.S. Food and Drug Administration (FDA) on Tuesday issued a directive requiring that manufacturers of gadolinium-based contrast agents (GBCAs) add a new warning to their product labeling that notifies healthcare providers that patients could retain gadolinium long after an MRI scan.  Discuss
X-ray fluorescence detects retained gadolinium in bone
December 19, 2017 -- As the safety of gadolinium MRI contrast is hotly debated, one of the challenges has been detecting gadolinium deposition in living patients. Canadian researchers may have found a solution to the dilemma with an x-ray fluorescence system that can noninvasively detect trace elements of gadolinium in exposed individuals.  Discuss
