半月板的MRI三维测量及临床意义

目的探讨半月板的MRI三维测量及临床意义。方法采用膝关节专用线圈对86只正常膝关节的半月板的前角、后角及体部进行高度和宽度的测量。结果内侧半月板前角、体部、后角的宽度和高度分别为4．53mm和7.89mm，5．79mm和8．65mm，5．39mm和11．32mm。外侧半月板前角、体部、后角的宽度和高度分别为4.73mm和9．23mm，6．39mm和9．87mm，6．15mm和9．62mm。结论半月板的MRI三维测量对诊断半月板疾病及半月板移植治疗具有重要的参考价值。

Three dimensional quantitative measurements of the menisci by MRI and its clinical Significance

Objective:To investigate the three dimensional quantitative measurements of menisci by the magnetic reso- nance imaging (MRI) and its clinical significance.Methods:Eighty-six normal knee joints were measured.The height and width of the anterior,mid-body and posterior horn of medial and lateral menisci were measured on MRI for limbs. Results:For the medial meniscus,the height and width of the anterior horn were 4.53mm and 7.89mm,the height of width of the mid-body were 5.79mm and 8.65mm,and the height and width of posterior were 5.39mm and 11.32mm, respectively.For the lateral meniscus,the height and width of the anterior horn were 4.73mm and 9.23mm;the height of width of the mid-body were 6.39mm and 9.87mm;and the height and width of posterior were 6.15mm and 9.62mm,re- spectively.Conclusion:The three dimensional quantitative measurements of menisci by the magnetic resonance imaging (MRI) have the significant value in the diagnosis of meniscus of the knee joint and meniscal replacement.
