Abstract

Over the past two decades, multidetector computed tomography (CT) has become a powerful diagnostic tool in emergency medicine relied upon for a variety of conditions. More recently, the development of dual-energy CT technology has enhanced the ability of radiologists to diagnose and distinguish between a variety of conditions, improving accuracy and patient care. The ability to separate material density pairs allows for highly specific observations, and helps to avoid diagnostic pitfalls. Dual-energy CT has benefits in diagnosing conditions of the liver, gallbladder, kidneys, adrenals, pancreas, large and small bowel, as well as vascular structures. It also has benefits in diagnostic evaluation of patients in the setting of trauma. When its benefits are harnessed, dual-energy CT has the potential to significantly improve patient care in the emergency department.
