摘　　要：目的探讨膝关节骨关节炎的关节软骨的MRI变化。方法收集膝关节骨性骨关节炎患者20例，分2组各10例，分别于半年和1年前后行MRI检查。采用FS-3D—FISP序列软骨成像，测量病损软骨的厚度；采用快速自旋双回波成像测量软骨病变的T2值。结果所有病变软骨厚度及T2值均有变化。半年组软骨T2值和厚度前后变化没有明显差异（P〉0．5）；1年组软骨T2值和厚度前后变化有明显差异（分别为P〈0．05和P〈0．005）。结论MRI可准确显示膝关节骨关节炎关节软骨的变化。Objective To study the changes of articular cartilage in osteoarthritis by MRI. Methods The knees in 20 cases of osteoarthritis were examined by MR. These cases were examined again by MRI half year later in 10 cases and one year later in 10 cases. The thickness of the disordered articular cartilage were measured on FS 3D-FISP sequence. T2 values of cartilage were also measured. Results T2 values and the thickness of disordered cartilages were not changed obviously in half years group. While one year later,the changes of disordered cartilages were significantly different （P〈0. 005）compared with that in the first examination. Conclusion MRI can show the changes of cartilage in osteoarthritis accurately.
