Tomo-CAD combo targets lung cancer screening
November 23, 2015 -- What if you had a lung cancer screening modality that was better than x-ray and nearly as good as CT, but with less radiation and expense? Researchers from Hungary are investigating the idea with a digital tomosynthesis system that they assembled themselves, along with homegrown computer-aided detection (CAD) software.
Skip abdominal x-ray for pediatric intussusception
November 20, 2015 -- There's no need to use abdominal radiography to diagnose pediatric intussusception -- ultrasound is better, and it does not expose children to radiation, according to a new study published in the journal Pediatric Surgery International.
Simulator training helps nonrads read chest x-rays
November 10, 2015 -- Nonradiologists can be taught to better detect nodules on chest radiographs using a training program that simulates a real-world radiology environment, rather than through more traditional didactic methods, according to a new study in the November Journal of the American College of Radiology.

October 13, 2015 -- A Texas hospital was able to cut radiologic technologist response time to 10 minutes for orders for stat mobile x-ray exams from the facility's medical intensive care unit, according to a September 29 article in the Journal of the American College of Radiology.
Choosing Wisely drives down imaging use -- sometimes
October 12, 2015 -- The Choosing Wisely initiative seems to have successfully reduced unnecessary utilization of two imaging exams in the U.S. that appeared on a list of overused medical tests, according to a study published October 12 in JAMA Internal Medicine. But two other questionable imaging tests saw no decline.
Study: Emergency patients get duplicate x-ray, CT exams
September 24, 2015 -- If Domino's can track pizzas from order through delivery, why can't we keep better track of patients? That's the question raised by a new study in the Journal of the American College of Radiology that found that many emergency patients got duplicate x-ray and CT exams because doctors weren't sure if their initial orders had been completed.
Decision model cuts unnecessary wrist x-rays by 22%
September 15, 2015 -- Using a clinical decision model developed by Dutch researchers for pediatric wrist trauma could cut unnecessary emergency x-ray imaging for the condition by 22% -- thereby reducing children's radiation exposure and healthcare costs, according to a study published online in Pediatric Radiology.
Digital tomo falls short of CT for lung nodules
September 14, 2015 -- Can digital tomosynthesis occupy a middle ground between CT and conventional radiography in lung imaging? A new study published September 8 in the Journal of Digital Imaging indicates that tomo may have a tough time finding a role in the chest that's not already well-served by the other two modalities.
