About this episode
Dr. Guillaume discusses the implications of increased CT angiography use in diagnosing gastrointestinal bleeding.
Gastrointestinal bleeding is a frequent and potentially life-threatening presentation in the ED. With CT angiography increasingly being used as a first-line diagnostic tool, are we improving detection or simply overusing imaging? Join Dr. Guillaume as she discusses this recent JAMA Network Open study examining trends in CTA utilization for GI bleeding and whether rising scan rates are truly leading to better diagnostic yield.
