Endoscopic ultrasonography (EUS) is currently an integral tool for work-up of pancreaticobiliary neoplasms. Tissue acquisition by EUS is possible with fine-needle aspiration (FNA) cytology and histology. However, FNA still carries some limitations and risks of complications. The use of image-enhanced EUS may improve detection and characterization of pancreaticobiliary neoplasms and complement FNA. The present article aims to provide an overview of the current development of contrast-enhanced imaging and elastography in EUS and their potential application in the diagnosis of pancreaticobiliary diseases.
内镜超声检查（EUS）目前是胰腺胆管肿瘤检查的重要工具。通过细针穿刺（FNA）细胞学和组织学检查可实现EUS引导下的组织获取。然而，FNA仍存在一些局限性和并发症风险。使用图像增强EUS可能会改善胰腺胆管肿瘤的检测和特征描述，并补充FNA的不足。本文旨在概述EUS中对比增强成像和弹性成像的当前发展及其在胰腺胆管疾病诊断中的潜在应用。
