摘要
目的:分析急性胼胝体梗死的核磁共振表现特征。方法:收治急性胼胝体梗死患者29例,均经核磁共振检查确诊,有完整的核磁共振检查资料。观察患者的核磁共振表现,并总结影像学资料特征。结果:29例患者经核磁共振共检出梗死灶36个,主要集中在右侧,呈卵圆形、圆形或条带状,无占位效应。梗死部位多为体部和压部,多合并基底节、额叶、脑干等其他颅内病灶梗死。在T1W1上呈低信号或稍低信号,在T2W1上及轴位自由水抑制上均呈高信号,轴位e P1序列弥散成像上呈高信号,T2W1矢状位病灶最清晰,增强扫描可见不均匀边缘强化。结论:核磁共振诊断急性胼胝体梗死,影像学特征明显,易于与其他颅内梗死病变鉴别。
Objective:To analyze the characteristics of nuclear magnetic resonance(MRI)in acute corpus callosum infarction.Methods:29patients with acute corpus callosum infarct were selected,all patients were diagnosed by nuclear magnetic resonance(MRI)and had complete MRI data.The patients were observed.We observed the nuclear magnetic resonance performance,and summarized the characteristics of imaging data.Results:A total of36infarcts were detected by magnetic resonance imaging(MRI)in29patients,mainly in the right side,oval,round or striped,without occupying effect.The main infarct site were body and pressure,combined with basal ganglia,frontal lobe,brain stem and other intracranial lesions infarction.In the T1W1showed low signal or slightly lower signal,in T2W1and axial free water inhibition were high signal,axial eP1sequence dispersion imaging showed high signal,T2W1sagittal lesions the most clear,enhanced scan visible uneven Edge enhancement.Conclusion:MRI diagnosis of acute corpus callosum infarction has obvious imaging features,easy to identify with other intracranial infarction,can be used as a clinical method of clinical diagnosis of the disease
