摘　　要：目的比较T_2加权像(T_2WI)、液体衰减反转恢复序列(Flair)与磁共振(MRI)三维双翻转恢复序列(3D-DIR)对多发性硬化(MS)患者脑内病变的检测能力。方法收集23例MS患者,采用3.0T MRI分别对23例颅内病变患者行T_2WI、Flair及3D-DIR序列扫描,比较三种序列对MS患者颅内不同部位病变的检出率。结果在总体病灶中,3种方法对皮质病灶及近皮质病灶的检出率差异有统计学意义(P<0.05),与T_2WI和Flair序列相比,3D-DIR对皮质病灶及近皮质病灶的检测更敏感。结论应用MR3D-DIR序列可以提高MS患者皮质病变及近皮质病变的检出率。Objective To compare the depiction of brain lesions by T2-weighted image,fluid-attenuatedinversion-recovery sequency and three-dimensional double inversion recovery sequence in patients with multiplesclerosis(MS).Method23patients with MS underwent magnetic resonance imaging(MRI)examination at3.0T,including T2WI,Flair and3D-DIR sequences,to compare the relevance ratio of lesions in different areas of thebrain at these three sequences.Results In total lesions,there were statistical differences among T2WI,Flair and3D-DIR sequences in detecting intracortical lesions and proximai cortical lesions,Compared with T2WI and Flair,3D-DIR was more sensitive to detect intracortical lesions and proximai cortical lesions.Conclusion MRI3D-DIRcan improve the detection of intracortical and proximai cortical lesions in patients with MS.
