Objective To analyze the correlation between serum hs -CRP levels and MR Imaging in ischemic cerebrovascu-lar patients.To explore the hs -CRP serum levels in ischemic cerebrovascular patients incidence of early diagnosis and prognosis e-valuation application value.Methods 300 cases of ischemic cerebrovascular disease as the research object were selected from May 2013 to December 2014.The disease is classified into acute cerebral infarction group 100 cases, acute phase of cerebral infarction group 140 cases and transient ischemic attack 60 cases.Among 100 cases of patients with acute cerebral infarction group, in accord-ance with the MR Imaging data, they can be subdivided into three groups.Group A: lacunar infarction group 28 cases; Group B:small area of infarction group 50 cases and group C: large area of infarction group 22 cases.Another 40 healthy physical examination were selected as control group.The hs -CRP serum levels were made correlation analysis with MR Imaging.Results The acute cerebral infarction and transient ischemic attack group serum hs -CRP level difference compared with the control group with statisti-cal significance (p<0.05); The SPSS Spearman correlation analysis result shows that the hs -CRP serum levels and MR Imaging data shown in the infarction area and the body has a direct correlation .Conclusion The ischemic cerebrovascular disease patients se-rum hs-CRP level with MR Imaging have shown increased infarct size and raise.Damage area is bigger, and the corresponding serum hs-CRP levels changes more violently.
