Magnetic resonance (MR) imaging of articular cartilage has recently become of intense interest because of new developments in the treatment of articular cartilage injury. Recent advances in MR imaging technology has allowed the development of imaging sequences tailored to the assessment of articular cartilage. Several clinical studies have validated the accuracy and reliability of high-resolution, fat-suppressed, three-dimensional, spoiled gradient-recalled MR imaging in the assessment of articular cartilage defects of the knee. The use of other MR imaging techniques is evolving, including the use of fast spin-echo imaging and anionic contrast-enhanced T1-weighted imaging. This article describes the background and rationale to MR imaging of articular cartilage and focuses on its clinical application. Because the knee has been the focus of most research in articular cartilage imaging, the discussion in this article will be largely restricted to this joint.
由于关节软骨损伤治疗方面的新进展，关节软骨的磁共振（MR）成像最近引起了广泛关注。MR成像技术的最新进展使得能够开发出专门用于评估关节软骨的成像序列。多项临床研究证实了高分辨率、脂肪抑制、三维、扰相梯度回波MR成像在评估膝关节软骨缺损方面的准确性和可靠性。其他MR成像技术的应用也在不断发展，包括快速自旋回波成像和阴离子对比增强T1加权成像的应用。本文介绍了关节软骨MR成像的背景和基本原理，并重点阐述了其临床应用。由于膝关节一直是关节软骨成像研究的重点，本文的讨论将主要局限于该关节。
