目的 探讨磁共振(MRI)中扩散加权成像(DWI)序列对可逆性胼胝体压部病变综合征(RESLES)的诊断价值。方法 回顾性纳入2021年5月至2023年4月医院30例RESLES患者为RESLES组,另纳入同期医院30例胼胝体压部缺血性脑梗死患者为对照组,两组患者入院时均接受MRI-DWI序列扫描检查,对比两组MRI表现特点及成像参数[表观扩散系数(ADC)],并绘制ROC分析ADC值对RESLES的诊断价值。结果 RESLES组患者病灶集中在胼胝体压部中线部,且在胼胝体压部中线处呈对称性排列,多为单发病灶,病灶形态相对规则,MRI扫描T1WI稍低信号,T2WI稍高信号,DWI高信号;对照组患者病变大都偏离胼胝体压部一侧,大都为多发病灶,病灶形态相对不规则,MRI扫描低信号,T2WI、DWI高信号;RESLES组ADC值比对照组低(P<0。05);绘制ROC曲线结果显示,ADC值诊断RESLES的AUC=0。767,具有一定诊断价值。结论 MRI扫描检查可清晰显示RESLES患者脑部病变数量、形态、分布情况等特征,能够为RESLES诊断提供重要依据,同时DWI序列参数对RESLES、胼胝体压部缺血性脑梗死具有一定鉴别诊断价值。
Diagnostic Value of DWI Sequence in MRI for Reversible Callosal Compression Syndrome
Objective To investigate the diagnostic value of diffusion weighted imaging(DWI)sequence in magnetic resonance imaging(MRI)for reversible splenial lesion syndrome(RESLES).Methods From May 2021 to April 2023,30 patients with RESLES in the hospital were retrospectively enrolled as the RESLES group,and 30 patients with ischemic cerebral infarction in the corpus callosum were enrolled as the control group.Both patients underwent MRI-DWI sequence scanning when they were admitted to the hospital.The MRI features and imaging parameters[apparent diffusion coefficient(ADC)]of the two groups were compared,and ROC was drawn to analyze the relationship between ADC values and RESLES.Results The lesions in the RESLES group were concentrated in the midline of the corpus callosum,and were symmetrically arranged at the midline of the corpus callosum,and most of them were single lesions with relatively regular morphology.MRI scan showed slightly low signal on T1WI,slightly high signal on T2WI and high signal on DWI.Most of the lesions in the control group deviated from the compression side of the corpus callosum,and most of them were multiple lesions with relatively irregular shapes.MRI scans showed high signals on T1WI,T2WI and DWI.The ADC value of RESLES group was lower than that of control group(P<0.05).The ROC curve shows that the AUC of ADC value in diagnosing RESLES is 0.767,which has certain diagnostic value.Conclusion MRI scanning can clearly show the number,shape and distribution of brain lesions in patients with RESLES,which can provide an important basis for the diagnosis of RESLES.At the same time,DWI sequence parameters have certain differential diagnostic value for ischemic cerebral infarction in RESLES and corpus callosum.
