CT、MRI在诊断脑后部可逆性脑病综合征中的价值

The Value of CT and MRI in the Diagnosis of Posterior Reversible Encephalopathy Syndrome

目的:试验并研究CT、MRI在诊断脑后部可逆性脑病综合征中的临床诊断价值。方法:从于2015年1月至2018年9月来我院进行脑后部可逆性脑病综合征(PRES)诊断治疗的156例患者,对其临床诊断资料进行回顾性分析与比较,并进行CT、MRI临床诊断。结果:CT平扫影像上显示在患者的脑白质区都存在左右对称、边界模糊的低密度、斑片状的影像,并且分布在患者的双侧顶枕叶;MRI扫描影像上则显示在患者的皮质下区或者白质区存在病灶信号,主要是呈现斑片状的异常信号。其中,T1WI上的病灶呈现出的是等信号或者稍低信号,T2WI与T1 FLAIR上的病灶则呈现为高信号,DWI主要呈现为等信号,病灶的边缘模糊,并且存在轻微占位效应。结论:运用CT、MRI扫描在诊断脑后部可逆性脑病综合征中能够提供有效的诊断参考依据,具有广泛的临床诊断价值,值得推广应用。

Objective: To study the clinical value of CT and MRI in the diagnosis of posterior reversible encephalopathy syndrome. Methods: 156 patients with posterior reversible encephalopathy syndrome (PRES) were diagnosed and treated in our hospital from January 2015 to September 2018. The clinical diagnosis data were retrospectively analyzed and compared, and the clinical diagnosis was made by CT and MRI. Results: CT plain scan showed symmetrical, blurred, low-density, patchy images in the white matter area of the patient, and distributed in the patient's bi-parietal and occipital lobes. MRI scan showed that there were lesion signals in the subcortical or white matter area of the patient, mainly showing patchy abnormal signals.. Among them, lesions on T1WI showed equal or slightly low signal, lesions on T2WI and T1FLAIR showed high signal, and lesions on DWI mainly showed equal signal, the edge of lesions was blurred, and there was a slight space-occupying effect. Conclusion: CT and MRI scanning can provide an effective diagnostic reference in the diagnosis of posterior reversible encephalopathy syndrome, which has a wide range of clinical diagnostic value and is worthy of popularization and application.
