目的:探讨MRI对诊断外伤所致膝关节损伤的能力。

方法:使用Picker公司15T超导MRI装置对50例膝关节进行检查。

结果:将MRI所显示的半月板损伤分为三级,明确指出了各级信号特点;提出了韧带损伤的直接和间接征象;并将膝部骨质隐匿性病灶分为五型,其中Ⅰ～Ⅲ型多见于急性损伤,Ⅳ～Ⅴ型多见于慢性损伤。

结论:由于MRI的信号特点及其可进行多平面成像,MRI在显示半月板、韧带、关节软骨及滑膜方面明显优于X线平片,在显示骨质情况尤其是显示隐匿性病灶时,可作为X线片的必要补充。

MRI diagnosis of traumatic injury of the knee-an imaging analysis

Abstract:

Objective:To evaluate the usefulness of MRI in knee joint trauma

Methods:MRI images of 50 cases of knee joints were obtained using Picker 1 5T MRI scanner, and compared with the plain films.

Results:The meniscus abnormalities in MRI films were classified into 3 degrees, and the character of every one degrees were described. The direct and indirect signs of the ligament trauma in MRI films were discussed. MRI appearances of osseous lesions in knee joints were classified to five categories,Ⅰ～ⅢMRI categories were commonly found in acute trauma, and Ⅳ～Ⅴ MRI categories were commonly found in chronic trauma.

Conclusion:MRI was better than plain films on showing the appearances of meniscus,ligament,articular cartilage, and synovial membrane. MRI showed intraosseous lesions of knee joint and was important supplements of the plain films.
