Background Information: Dual-energy CT (DECT) allows enhanced tissue characterization using material decomposition and has found increasing applications in clinical practice. In patients presenting to the emergency department with acute abdomen, DECT has potentially demonstrated a growing spectrum of clinical applications.

Educational Goals/Teaching Points: The goal of this exhibit is to discuss the DECT technology and imaging technique with a particular focus on the emergency setting. We review the various clinical applications of DECT in management of acute abdomen. Additionally, we describe limitations and challenges in integration of DECT with the emergency setting.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: The exhibit will review DECT technologies and imaging protocols and clinical applications of DECT in acute abdomen including gastrointestinal bleeding, trauma to the abdomen, gastrointestinal emergencies, and genitourinary emergencies. The exhibit will also discuss the challenges and limitations of DECT and provide a case-based pictorial review of interesting DECT manifestations of acute abdomen.

Conclusion: DECT is an exciting innovation in CT technology with immense potential applications in evaluation of patients with acute abdomen. Knowledge of the techniques, applications, advantages, and limitations of DECT are imperative to fully explore its potential to improve patient care in an emergent setting.
