Magnetic resonance (MR) imaging is one of the most commonly used imaging modality for evaluating patients with joint pain. Musculoskeletal MR protocols at most institutions consist of 2-dimensional fast spin echo (FSE) sequences repeated in multiple planes. Three-dimensional sequences have also been used to evaluate the musculoskeletal system and have many potential advantages over 2-dimensional FSE sequences. Three-dimensional sequences acquire thin continuous slices through joints with high in-plane spatial resolution, which minimize the effects of partial volume averaging. Newly developed 3-dimensional isotropic resolution sequences can also be used to create high-quality multiplanar reformat images that allow joints to be evaluated in any orientation after a single acquisition. Preliminary results on the use of 3-dimensional isotropic resolution sequences for evaluating the musculoskeletal system are encouraging. However, additional studies are needed to document the advantages of 3-dimensional sequences before they can replace currently used 2-dimensional FSE sequences for evaluating the musculoskeletal system in clinical practice.
磁共振（MR）成像 是评估关节疼痛患者时最常用的成像方式之一。大多数机构的肌肉骨骼MR检查方案由在多个平面重复的二维快速自旋回波（FSE）序列组成。三维序列也已用于评估肌肉骨骼系统，并且与二维FSE序列相比具有许多潜在优势。三维序列通过关节获取具有高平面内空间分辨率的薄连续切片，这将部分容积平均的影响降至最低。新开发的三维各向同性分辨率序列也可用于创建高质量的多平面重组图像，从而在单次采集后能够以任何方向评估关节。使用三维各向同性分辨率序列评估肌肉骨骼系统的初步结果令人鼓舞。然而，在三维序列能够取代目前用于临床实践中评估肌肉骨骼系统的二维FSE序列之前，还需要进行更多研究来证明其优势。
