Evaluate Value of Diffusion Weighted Imaging MRI in Evaluating the Degree of Nerve Damage in Patients with Acute Cerebral Infarction
Objective:To explore the evaluate value of diffusion weighted imaging(DWI)magnetic resonance imaging(MRI)in evaluating the degree of nerve damage in patients with acute cerebral infarction.Method:A total of 150 patients with acute cerebral infarction treated in Suzhou Xiangcheng People's Hospital from September 2021 to August 2023 were retrospectively selected.According to NIHSS score,the patients were divided into mild-moderate group(65 cases)and severe group(85 cases).Both groups underwent routine MRI examination and DWI examination.The apparent diffusion coefficient(ADC)and relative apparent diffusion coefficient(ADC),infarct volume and FLAIR vascular hyperintensity(FVH)sign score of the two groups were compared.The correlation among infarct volume,FVH sign score,ADC and rADC and the severity of acute cerebral infarction was analyzed.The diagnostic value of infarct volume,FVH syndrome score and ADC on the severity of acute cerebral infarction was analyzed.Result:ADC and rADC in severe group was higher than that in mild-moderate group,and the difference was statistically significant(P<0.05).FVH sign score and infarct volume in severe group were higher than those in mild-moderate group,and the differences were statistically significant(P<0.05).Infarct volume,FVH sign score,ADC and rADC were positively correlated with disease severity(P<0.001).Conclusion:MRI DWI has high accuracy and sensitivity in evaluating the degree of nerve damage in patients with acute cerebral infarction,and has high diagnostic value.
