Dual-energy computed tomography (DECT) is an exciting technology that is increasing in routine use and has the potential for significant clinical impact. With the advancement of DECT, it is important for radiologists to be aware of potential challenges with DECT acquisition and postprocessing, and to have a basic knowledge of unique artifacts and diagnostic pitfalls that can occur when interpreting DECT scans and DECT postprocessed images. This article serves as a practical overview of potential problems and diagnostic pitfalls associated with DECT, and steps that can be taken to avoid them.
双能计算机断层扫描（DECT）是一项令人振奋的技术，其在常规应用中不断增加，并且具有产生重大临床影响的潜力。随着DECT的发展，放射科医生了解DECT采集和后处理中的潜在挑战，以及掌握在解读DECT扫描图像和DECT后处理图像时可能出现的独特伪影和诊断陷阱的基本知识非常重要。本文对与DECT相关的潜在问题和诊断陷阱以及可采取的避免措施进行了实用概述。
