Magnetic resonance imaging appears to be a particularly promising approach to the evaluation of articular and periarticular abnormalities. Its ability to produce images in multiple planes directly (without reconstruction) provides a unique advantage over CT for the radiologist when he attempts to interpret the complex three dimensional anatomy of most joints. The inherent contrast resolution of MR is excellent, and with the use of surface coils, spatial resolution is sufficient to permit the identification of the small soft tissue structures in and around joints. Artifacts generated by respiratory and cardiac motion are not a problem in MRI of the joints as they are in MR scanning of the body. Based on all these qualities, we believe that MRI will play an important role in the diagnosis of joint abnormalities.
磁共振成像似乎是评估关节及关节周围异常情况的一种特别有前景的方法。它能够直接在多个平面上生成图像(无需重建),这在放射科医生试图解读大多数关节复杂的三维解剖结构时,相较于CT具有独特优势。MR固有的对比分辨率极佳,并且通过使用表面线圈,空间分辨率足以识别关节内及周围的小软组织结构。呼吸和心脏运动产生的伪影在关节的MRI中不像在身体的MR扫描中那样是个问题。基于所有这些特性,我们认为MRI将在关节异常的诊断中发挥重要作用。
