近年来，3 T MRI技术发展十分迅速，已广泛应用于软骨病变的诊断和疗效评价。各种软骨成像序列不断被开发和应用，目前已从传统的二维、三维形态成像向生化成分成像转变，以期能够对关节软骨形态学改变之前的软骨生化改变进行显示，为早期软骨损伤诊断和监测提供临床参考依据。目前，关节软骨生化成分成像技术包括T2 mapping、T2*mapping及T1ρ成像等。就3 T MR关节软骨生化成分成像的临床应用及研究进展予以综述。

In recent years, 3 T MRI system is growing so rapidly that it has been widely used in the diagnosis and evaluation of the curative efficacy of cartilage lesions. The various imaging sequences of cartilage are being developed and applied constantly. Nowadays it begins to transform from traditional two dimensional and three dimensional morphological imaging to biochemical composition imaging. The biochemical composition imaging can show the biochemical changes prior to morphological changes of cartilage and provide clinical references about early diagnosis and monitoring of cartilage damage. At present, the biochemical composition imaging technology of articular cartilage includes T2 mapping, T2*mapping, T1ρ, etc. In this paper, we reviewed the applications and progresses of 3 T MRI biochemical composition imaging in articular cartilage.
