【摘要】 目的 探究1.5T高场磁共振在胼胝体变性诊断及鉴别诊断中的应用价值。方法 选取8例经过磁共振成像确定的胼胝体变性患者进行常规矢状面T2WI序列扫描, 同时进行轴位T2WI、磁共振扩散加权成像(DWI)、T1WI、FLAIR等序列扫描, 判断1.5T高场磁共振在胼胝体变性诊断及鉴别诊断中的实际应用效果。结果 8例患者经过1.5T高场磁共振诊断均呈现出对称分布的病灶, 且矢状位T2WI序列表现为较为典型的“夹心蛋糕征”, 6例患者DWI均呈现出弥散受限状態。结论 1.5T高场磁共振在胼胝体变性疾病检查中具有较为明显的效果, 可以及时判断出患者是否发生胼胝体变性疾病, 因此具有更高的应用价值。

【Abstract】 Objective To investigate the application value of 1.5T high field magnetic resonance in the diagnosis and differential diagnosis of corpus callosum degeneration. Methods A total of 8 corpus callosum degeneration patients confirmed by magnetic resonance imaging all received conventional sagittal T2WI sequence scan, and sequence scans of axial T2WI, magnetic resonance diffusion weighted imaging (DWI), T1WI and FLAIR at the same time, so as to determine the practical effect of 1.5T high field magnetic resonance in the diagnosis and differential diagnosis of corpus callosum degeneration. Results 8 patients had symmetrical lesions diagnosed by 1.5T high field magnetic resonance, and the sagittal T2WI sequence showed a typical “sandwich cake” sign. DWI of 6 patients showed a diffusion-limited state. Conclusion 1.5T high field magnetic resonance provides obvious effect in the examination of corpus callosum degeneration disease, and it can promptly determine the occurrence of corpus callosum degeneration disease. So it contains higher application value.

胼胝体变性也被称为原发性胼胝体变性, 该疾病属于脱髓鞘性病变, 相对较为罕见, 目前为止, 医学研究领域并没有研究出胼胝体变性疾病的致病原因, 但是该疾病多发于慢性酒精中毒患者[1]。由于致病原因不明, 因此提高治疗有效性就要尽早诊断出患者是否患有原发性胼胝体变性疾病, 因该疾病在临床中缺少特异性表现, 通过直观判断无法有效为患者诊断出病情, 而使用1.5T高场磁共振手段为胼胝体变性患者进行诊断时, 能够产生特征性影像, 且随着影像诊断学发展, 对胼胝体变性患者的早期诊断可能率逐渐提高。
