Abstract

As the access of radiology practices to dual-energy CT (DECT) has increased worldwide, seamless integration into clinical workflows and optimized use of this technology are desirable. In this article, we provide basic concepts of commercially available DECT hardware implementations, discuss financial and logistical aspects, provide tips for protocol building and image routing strategies, and review radiation dose considerations to establish a DECT service line in abdominal imaging.

Key Points

• Tube-based and detector-based DECT implementations with varying features and strengths are available on the imaging market.
• Thorough assessment of financial and logistical aspects is key to successful implementation of a DECT service line.
• Optimized protocol building and image routing strategies are of critical importance for effective use and seamless inception of DECT in routine clinical workflows.
