There is an increasing need for an accurate, noninvasive technique for the evaluation of cartilage. Magnetic resonance (MR) imaging, with its excellent contrast resolution and multiplanar imaging capability, was considered by many as the future gold standard for chondral imaging. Although substantial improvements in MR technology and understanding have occurred, the ideal imaging protocol and the role of MR imaging for cartilage evaluation has not been established. A confusing plethora of sequences have been advocated, with variable results and reproducibility. Often, techniques are not widely available or feasible from a practical point of view and many still require rigorous clinical evaluation. MR arthrography, although invasive and time consuming, provides excellent detailed evaluation of cartilage and can rival arthroscopy for the preoperative evaluation of traumatic osteochondral lesions or osteochondritis dissecans. Recently, encouraging results have been obtained with fat-suppressed imaging; however, further clinical trials are still awaited. This article attempts to place the various chondral MR imaging sequences in perspective, with discussion of their relative benefits and disadvantages.
对用于评估软骨的准确、非侵入性技术的需求日益增加。磁共振(MR)成像具有出色的对比度分辨率和多平面成像能力,被许多人视为软骨成像的未来金标准。尽管MR技术和认识有了实质性的进步,但理想的成像方案以及MR成像在软骨评估中的作用尚未确立。人们提倡了大量令人困惑的序列,其结果和可重复性各不相同。通常,从实际角度来看,这些技术并不广泛可用或不可行,而且许多技术仍需要严格的临床评估。MR关节造影虽然具有侵入性且耗时,但能对软骨进行出色的详细评估,在术前评估创伤性骨软骨损伤或剥脱性骨软骨炎方面可与关节镜检查相媲美。最近,脂肪抑制成像取得了令人鼓舞的结果;然而,仍有待进一步的临床试验。本文试图对各种软骨MR成像序列进行客观分析,并讨论它们的相对优缺点。
