摘要

双能计算机断层扫描已成为腹部成像的关键工具,特别是对于胰腺病理,如胰腺导管腺癌、创伤评估和急性胰腺炎。它能够提供增强的对比度分辨率,减少伪影,优化辐射剂量,使其在急性和非急性临床环境中都非常宝贵。本文综述双能计算机断层扫描在胰腺成像中的技术进展和临床应用。对2013年至2024年间发表的21项同行评审研究进行了全面回顾,以评估双能计算机断层扫描在所有胰腺成像指征中的作用,包括肿瘤检测、胰腺炎评估、创伤评估和辐射剂量优化。分析包括从多个数据库检索的回顾性和前瞻性研究,包括PubMed、Scopus和谷歌Scholar。这些发现强调了该技术通过虚拟单能成像和碘定量等技术提高诊断准确性、减少图像伪影和降低辐射暴露的能力。与传统计算机断层扫描的比较主要集中在诊断性能指标,如对比噪声比和信噪比。此外,这篇叙述性综述强调了双能量计算机断层扫描在评估非创伤性急性腹部疾病中的临床意义,特别是在老年患者中。

Advances in Pancreatic Imaging: The Expanding Role of Dual-Energy CT in Clinical Diagnosis: A Comprehensive Review.

Dual-energy computed tomography has become a pivotal tool in abdominal imaging, particularly for pancreatic pathologies such as pancreatic ductal adenocarcinoma, trauma assessment, and acute pancreatitis. Its ability to provide enhanced contrast resolution, reduce artifacts, and optimize radiation dose makes it invaluable in both acute and non-acute clinical settings. This narrative review summarizes the technological advancements and clinical applications of dual-energy computed tomography in pancreatic imaging. A comprehensive review of 21 peer-reviewed studies published between 2013 and 2024 was conducted to evaluate the role of dual-energy computed tomography in all pancreatic imaging indications, including tumor detection, pancreatitis assessment, trauma evaluation, and radiation dose optimization. The analysis included retrospective and prospective studies retrieved from multiple databases, including PubMed, Scopus, and Google Scholar. The findings highlight the technology's capacity to improve diagnostic accuracy, reduce image artifacts, and lower radiation exposure through techniques such as virtual monoenergetic imaging and iodine quantification. Comparisons with conventional computed tomography focused on diagnostic performance metrics such as contrast-to-noise ratio, and signal-to-noise ratio. Additionally, this narrative review underscores the clinical relevance of dual-energy computed tomography in evaluating non-traumatic acute abdominal conditions, especially among elderly patients.
