超声造影在胆囊疾病中的诊断作用

Roles of Contrast-Enhanced Ultrasound in Diagnosis of Gallbladder Diseases

超声造影技术又称为超声对比增强,是利用超声造影剂使血液散射回声增强,明显提高超声诊断的分辨力、敏感性和特异性的技术。该技术可以克服常规超声检查的局限性,提高胆囊良恶性疾病的诊断率,评价胆囊癌对临近肝组织浸润的情况以及评价肾功能不全患者的胆囊疾病情况。本文介绍了超声造影的基本原理,胆囊疾病超声造影的必要性,总结了近些年来国内外部分学者对胆囊疾病的造影超声诊断价值的研究,就不同病理类型疾病的造影特点、造影对良恶性病变鉴别价值、造影在胆囊疾病诊断中的优缺点以及未来发展方向进行了阐述。

Contrast-enhanced ultrasound (CEUS) was also called ultrasonic contrast enhancement,which using ultrasound contrast to increase the echo of blood scattering, improving the definition of ultrasonic diagnosis, and its sensitivity and specificity. This technique could overcome the limitations of conventional ultrasound examination, improve the diagnosis of benign and malignant gallbladder lesions,evaluate the adjacent hepatic metastasis and gallbladder diseases in patients with renal dysfunction.This paper introduced the principle of CEUS and indications for gallbladder diseases, summarized the diagnostic values of gallbladder diseases studied by scholars at home and abroad in recent years, and elaborated CEUS characteristics of several pathological identities, differentiating values of benign and malignant lesions, advantages and disadvantages of CEUS in gallbladder disease diagnosis, and its perspectives.
