AI algorithm predicts lung disease, adverse events on CT
October 13, 2017 -- Recent studies have demonstrated the power of artificial intelligence (AI) software to detect disease, but how well can it predict future adverse events? The extent to which AI can assess smokers' risk for lung disease on CT was reported in a new study published in the American Journal of Respiratory and Critical Care Medicine.  Discuss
AI gives one-stop shopping for urinary stone evaluation
October 5, 2017 -- An artificial intelligence (AI) algorithm can accurately detect and classify urinary stones based solely on images from noncontrast single-energy CT scans, according to research presented at last week's Society for Imaging Informatics in Medicine's Conference on Machine Intelligence in Medical Imaging.  Discuss
Imaging lands high on list of overused medical exams
October 5, 2017 -- Medical imaging exams occupied five of the top 10 spots in a literature review of studies on overused medical procedures published October 2 in JAMA Internal Medicine. The study authors recommended that additional regulation might be necessary to curb practices that increase healthcare costs and do not help patients.  Discuss
CT radiation dose tracking reveals global disparities
October 3, 2017 -- The growing use of radiation dose tracking software has revealed an inconvenient truth: There are substantial differences around the world in the amount of radiation dose being used for CT scans, according to a Swiss study published online in the American Journal of Roentgenology.  Discuss
Can MRI challenge CT in diagnosing appendicitis?
September 29, 2017 -- CT has long been the go-to tool for diagnosing appendicitis in kids, but concerns about radiation have radiologists exploring other modalities. Whether MRI could be one of these alternatives was the subject of a study published in the October issue of the American Journal of Roentgenology.  Discuss
CTA helps direct use of clot removal for stroke patients
September 26, 2017 -- Determining which stroke patients should undergo mechanical clot removal hinges on a complex network of clinical imaging factors. Measuring collateral blood flow through CT angiography (CTA) can help optimize the process, according to a study published online September 25 in JAMA Neurology.  Discuss
Study questions value of CT scans after NCSLC surgery
September 15, 2017 -- Performing frequent CT scans after surgery for non-small cell lung cancer (NSCLC) may not necessarily improve overall patient survival rates, according to findings presented at the European Society for Medical Oncology 2017 congress in Madrid.  Discuss
Simple interventions reduce outpatient CT wait times
September 12, 2017 -- Many patient visits to the hospital involve imaging, and one of the most important metrics patients use to measure satisfaction with radiology services is exam wait time. So how can wait time be streamlined?  Discuss
Bottoms up: Oral contrast preferred over missed finding
August 31, 2017 -- If given a choice between drinking oral CT contrast and missing a finding on an unenhanced imaging scan, patients prefer the contrast, according to results of a study published August 28 in the Journal of the American College of Radiology.  Discuss
Kids get more CT radiation at nonpediatric hospitals
August 28, 2017 -- Children who had CT scans at nonpediatric hospitals in Arkansas received twice the radiation dose as kids who were scanned at hospitals with a dedicated pediatric trauma center using optimized scanning protocols, according to a study published online August 25 in the Journal of the American College of Radiology.  Discuss
