摘要
目的探讨磁敏感成像(SWI)对脑外伤微出血的诊断价值。方法对57例脑外伤患者,应用1.5TMR行常规MRI和SWI序列成像检查并结合临床资料进行分析。结果 SWI检出微出血灶55例(96.5%),常规序列检出47例(82.4%),SWI检出8例有脑微出血病灶患者而常规序列阴性,两者对脑内出血检出率差别有统计学意义(P<0.05)。结论 SWI序列对脑内微出血的敏感性高,对脑外伤微出血患者的诊断和治疗有显著的价值。
Objective To explore the diagnostic value of susceptibility weighted imagiag （SWI） in patients with traumatic cerebral microbleeds. Methods 57 patients with traumatic brain Injury were subjected to SWI and conventional MRI sequences at 1.ST MR scanner The imaging foundings and related clinical data were analyzed. Results 55 patients were showed by SWI, and47 patients were showed by conventional MRI sequences ,8 patients with traumatic brain Injury were found by SW1 but conventional MRI sequences were negative It had statistically difference between two groups. Conclusion SWI is semitive to cerebral microbleeds and it has predominant value in diagnosis and treatment to patients with traumatic cerebral microbleeds
