Sonography经常是腹部诊断调查中首个使用的成像程序。本文的目的是提供一个新的跨学科综述，介绍这种技术的最新突破性进展。在PubMed的文献中进行了选择性的检索。文献检索在2021-2022年进行，包括2004年至2022年的出版物。新型超声软件技术可以分为处理传统B型扫描优化的算法和扩展超声检查范围的新程序。后者包括弹性成像、增强对比超声和与其他横向成像模式结合的图像融合。弹性成像可用于评估患有肝病的患者中脂肪肝、纤维化或肝硬化的存在。一项研究报告了对显著纤维化（F2）的诊断准确率为84-87％，对严重纤维化（F3）的诊断准确率为89-91％，对肝硬化（F4）的诊断准确率为92-93％。增强对比超声用于肿瘤和创伤的评估。一项前瞻性多中心研究发现，其判别恶性病变的敏感性为95.8％，良性病变的特异性为83.1％。图像融合有潜力改善实质器官、血管疾病和前列腺的诊断评估。随着B型扫描的不断改进和高频探头和新型调查技术的发展，超声已成为越来越自主的检查程序。

Sonography is often the first imaging procedure to be used in diagnostic investigation of the abdomen. The aim of this article is to provide a new interdisciplinary overview of recent groundbreaking advances in this modality.A selective survey of the literature in PubMed was conducted. The literature search was carried out in 2021‒2022 and included publications over the period 2004-2022.The novel sonographic software techniques can be divided into algorithms that deal with conventional B-scan optimization and new programs that extend the scope of sonographic examination. The latter include elastography, contrast-enhanced sonography, and image fusion in combination with other cross-sectional imaging modalities. Elastography can be used to assess the presence of steatosis, fibrosis, or cirrhosis in patients with liver disease. One study reported diagnostic accuracy of 84-87% for the diagnosis of significant fibrosis (F2), 89‒91% for the diagnosis of severe fibrosis (F3), and 92‒93% for the diagnosis of liver cirrhosis (F4). Contrast-enhanced sonography is used for evaluation of tumors and trauma. A prospective multicenter study found sensitivity of 95.8% for the characterization of malignant lesions and specificity of 83.1% for benign lesions. Image fusion has the potential to improve the diagnostic assessment of parenchymatous organs, vascular conditions, and the prostate.With continuous improvement of the B-scan and the development of high-frequency probes and novel investigation techniques, sonography has become established as an increasingly autonomous examination procedure.
