ＭＲ是一种无创性的安全检查方法。ＭＲ是磁场内核能量吸收和发射产生的一种现象 ,它依赖于能影响组织化学特性的内在组织参数 ,尤其是人体组织内的氢原子 ,这是ＭＲＩ的基础。肌肉骨骼组织成分特别适于做ＭＲ检查 ,ＭＲＩ正逐渐推广应用于骨关节病变的诊断和鉴别诊断[1] ,有助 MR is a non-invasive method of safety inspection. MR is a phenomenon that arises from the energy absorption and emission in the magnetic core. It relies on intrinsic tissue parameters that affect histochemical properties, especially hydrogen atoms in human tissues, which is the basis of MRI. Musculoskeletal tissue composition is particularly suitable for MR examination, MRI is gradually applied to the diagnosis and differential diagnosis of bone and joint disease [1], is helpful
