Magnetic resonance imaging (MRI) represents the preferred noninvasive imaging technique to diagnose meniscal pathology in the pre- and postoperative setting. Furthermore, characterization of meniscal tissue MR properties has been possible by the development of advanced MRI techniques. Suspected meniscal tears are a frequent indication for MRI and the International Society of Arthroscopy, Knee Surgery and Orthopaedic Sports Medicine (ISAKOS) classification system has been developed to facilitate accurate and uniform reporting of such meniscal tears. Partial meniscectomy and meniscal suture repair are among the commonly performed procedures and several signs have been described to detect postoperative recurrent tears on MRI. Other techniques that have proven useful for meniscal assessment are ultrasound (US) and computed tomography (CT) arthrography. In recent years, US is being increasingly used in the selective assessment of some meniscal pathology such as tears, parameniscal cysts and meniscal extrusion as it is a relatively inexpensive, accessible, and safe technique. CT arthrography has been advocated as an acceptable alternative in patients with contraindications for MRI, with comparable diagnostic performance.
磁共振成像（MRI）是术前和术后诊断半月板病变的首选非侵入性成像技术。此外，先进MRI技术的发展使得对半月板组织的磁共振特性进行表征成为可能。疑似半月板撕裂是MRI的常见指征，国际关节镜、膝关节手术和骨科运动医学学会（ISAKOS）制定了分类系统，以促进对此类半月板撕裂进行准确和统一的报告。部分半月板切除术和半月板缝合修复是常见的手术，并且已经描述了几种在MRI上检测术后复发性撕裂的征象。其他已被证明对半月板评估有用的技术是超声（US）和计算机断层扫描（CT）关节造影。近年来，超声越来越多地用于某些半月板病变的选择性评估，如撕裂、半月板旁囊肿和半月板挤出，因为它是一种相对便宜、可及且安全的技术。CT关节造影已被提倡作为MRI禁忌患者的可接受替代方法，其诊断性能相当。
