Abstract

Endoscopic ultrasound (EUS) is one of the most important modalities for the diagnosis of digestive tract diseases. EUS has been evolving ever since it was introduced. New techniques such as elastography and contrast enhancement have emerged, increasing the accuracy, sensitivity and specificity of EUS for the diagnosis of digestive tract diseases including pancreatic masses and lymphadenopathy. EUS-elastography evaluates tissue elasticity and therefore, can be used to differentiate various lesions. Contrast-enhanced EUS can distinguish benign from malignant pancreatic lesions and lymphadenopathy using the intravenous injection of contrast agents. This review discusses the principles and types of these new techniques, as well as their clinical applications and limitations.

摘要

内镜超声(EUS)是诊断消化道疾病最重要的手段之一。自引入以来,EUS一直在不断发展。弹性成像和对比增强等新技术不断涌现,提高了EUS对包括胰腺肿块和淋巴结病在内的消化道疾病诊断的准确性、敏感性和特异性。EUS弹性成像可评估组织弹性,因此可用于鉴别各种病变。对比增强EUS可通过静脉注射造影剂来区分胰腺良恶性病变及淋巴结病。本文综述讨论了这些新技术的原理、类型及其临床应用和局限性。
