Endometriosis is a common yet morbid disease. Imaging plays an important role in diagnosis and treatment planning. Both ultrasound (US) and MRI are used to detect disease. We performed a literature review to assess whether one is superior. A total of 33 studies from the 4482 identified in the initial search were found to assess the efficacy of US and/or MRI in detecting pelvic endometriosis. Most studies were performed at centers with extensive experience with endometriosis, using dedicated US and MRI protocols. A wide range of sensitivities and specificities was reported, but overall weighted means of diagnostic statistics between US and MRI were similar. The choice of dedicated US versus MRI in evaluation of endometriosis should therefore be based on the expertise in the region. The data also showed US had better accuracy for identifying depth of wall invasion in bowel wall disease, whereas MRI better visualized pelvic wall and extraperitoneal disease. Routine US and MRI protocols performed worse than dedicated US and MRI protocols, which may account for delays in diagnoses. Clinical and research efforts directed at improving the sensitivity of routine imaging for diagnosing deep endometriosis could improve patient access to appropriate care.
子宫内膜异位症是一种常见的多发病。影像学检查在诊断和治疗计划中发挥着重要作用。超声波（US）和核磁共振成像都可用于检测疾病。我们进行了文献综述，以评估二者是否各有优劣。在最初搜索到的 4482 项研究中，我们发现共有 33 项研究评估了 US 和/或 MRI 在检测盆腔子宫内膜异位症方面的疗效。大多数研究都是在对子宫内膜异位症有丰富经验的中心进行的，并采用了专门的 US 和 MRI 方案。报告的敏感性和特异性范围很广，但 US 和 MRI 的总体加权诊断统计平均值相似。因此，在评估子宫内膜异位症时，应根据该地区的专业知识选择专用的 US 和 MRI。数据还显示，在确定肠壁疾病的侵壁深度方面，US 的准确性更高，而 MRI 能更好地观察盆腔壁和腹膜外疾病。常规 US 和 MRI 方案比专用 US 和 MRI 方案表现更差，这可能是诊断延误的原因。为提高常规成像诊断深部子宫内膜异位症的灵敏度而开展的临床和研究工作可改善患者获得适当治疗的机会。

Quantitative ultrasound (QUS) and ultrasound-based elastography techniques are emerging as non-invasive effective methods for assessing chronic liver disease. They are more accurate than B-mode imaging alone and more accessible than MRI as alternatives to liver biopsy. Early detection and monitoring of diffuse liver processes such as steatosis, inflammation, and fibrosis play an important role in guiding patient management. The most widely available and validated techniques are attenuation-based QUS techniques and shear-wave elastography techniques that measure shear-wave speed. Other techniques are supported by a growing body of evidence and are increasingly commercialized. This review explains general physical concepts of QUS and ultrasound-based elastography techniques for evaluating chronic liver disease. The first section describes QUS techniques relying on attenuation, backscatter, and speed of sound. The second section discusses ultrasound-based elastography techniques analyzing shear-wave speed, shear-wave dispersion, and shear-wave attenuation. With an emphasis on clinical implementation, each technique's diagnostic performance along with thresholds for various clinical applications are summarized, to provide guidance on analysis and reporting for radiologists. Measurement methods, advantages, and limitations are also discussed. The third section explores developments in quantitative contrast-enhanced and vascular ultrasound that are relevant to chronic liver disease evaluation.
定量超声（QUS）和超声弹性成像技术正在成为评估慢性肝病的无创有效方法。作为肝活检的替代方法，它们比单纯的 B 型成像更准确，比核磁共振成像更容易获得。早期检测和监测弥漫性肝脏病变，如脂肪变性、炎症和纤维化，在指导患者管理方面发挥着重要作用。目前最广泛使用和经过验证的技术是基于衰减的 QUS 技术和测量剪切波速度的剪切波弹性成像技术。其他技术也有越来越多的证据支持，并日益商业化。本综述解释了用于评估慢性肝病的 QUS 和超声弹性成像技术的一般物理概念。第一部分介绍了基于衰减、反向散射和声速的 QUS 技术。第二部分讨论了分析剪切波速度、剪切波弥散和剪切波衰减的超声弹性成像技术。以临床应用为重点，总结了每种技术的诊断性能以及各种临床应用的阈值，为放射科医生的分析和报告提供指导。此外，还讨论了测量方法、优势和局限性。第三部分探讨了与慢性肝病评估相关的定量对比增强和血管超声的发展。
