摘要：

背景：核磁共振检查弥补了X射线平片及CT在软骨成像方面的不足，能对骨挫伤和关节软骨损伤做出早期诊断。
目的：探讨MRI对股骨远端负重区骨挫伤合并关节软骨损伤的诊断价值。
方法：股骨远端骨挫伤35例，观察关节镜下关节软骨损伤情况，比较与MRI所见骨挫伤之间的相关性。
结果与结论：关节镜下所见关节软骨损伤与MRI所示股骨远端负重区骨挫伤部位基本吻合，后者信号改变的范围与软骨损伤面积成正比。提示，MRI对骨挫伤合并的关节软骨损伤有良好的诊断价值，尤其Ⅰ度软骨损伤，骨挫伤是重要的间接征象。但在某些情况下MRI尚不能真实反映出关节软骨损伤的严重程度。

Abstract:

BACKGROUND: Magnetic resonance imaging (MRI) makes up for a deficiency of X-ray plain films and CT images in cartilage imaging, and can be involved in early diagnosis of bone bruise and cartilage injury.
OBJECTIVE: To explore the value of MRI in diagnosis of articular cartilage injuries complicated with bone bruise of the distal femur.
METHODS: Thirty-five cases of articular cartilage injuries complicated with bone bruise of the distal femur diagnosed by MRI were examined under arthroscopy.
RESULTS AND CONCLUSION: The site of articular cartilage injuries complicated with bone bruise of the distal femur examined under arthroscopy corresponded to MRI findings. The injuries showed by arthroscopy were in direct proportion to MRI. MRI plays an important role in evaluating articular cartilage injuries complicated with bone bruises, and bone bruises are considered as an indication of articular cartilage injuries. While sometimes MRI cannot deliver the severity of cartilage injuries because of instrumental factors.
