多模式磁共振检查对急性脑出血患者的应用价值

Application Value of Multimode Magnetic Resonance Inspection in Patients with Acute Cerebral Hemorrhage

目的探讨多模式MRI检查对急性脑出血患者的应用价值。方法收集53例急性脑出血患者的CT和多模式MRI影像资料,对比CT和多模式MRI对急性脑出血、动脉瘤、动静脉畸形、脑微出血的检出率,采用配对χ2检验。对比CT与MRI测量急性脑出血体积,采用Wilcoxon带符号秩检验。结果 CT与多模式MRI对急性脑出血、动脉瘤、动静脉畸形、脑微出血的检出率分别为100%VS 100%、0 VS 13.2%、0 VS 3.8%、0 VS 28.3%。T2WI、DWI、T2*GRE、CT测量急性脑出血体积中位数(四分位数)分别为5.5(2.0,10.7)mL、7.6(3.1,13.0)mL、8.9(3.3,15.9)mL、8.6(3.1,15.2)mL,T2WI、DWI测量血肿体积与CT比较差异均有统计学意义(P<0.05),T2*GRE与CT比较差异无统计学意义(P>0.05)。结论对于急性脑出血患者,多模式MRI在短时间内一次性检查即可为临床诊治方案的制定提供可靠、较全面的影像信息。

Objective To explore the application value of Multimode magnetic resonance imaging(MRI)inspection in patients with acute cerebral hemorrhage.Methods CT and multimode MRI of 53 patients with acute intracerebral hemorrhage were collected.The detection rates of acute cerebral hemorrhage,arterial aneurysm,arteriovenous malformation(AVM)and cerebral microbleeds(CMBs)were compared between CT and multimode MRI.Group differences were evaluated with Pairedχ2 test.The volumes of acute cerebral hemorrhage measured by CT and MRI were also compared.Group differences were evaluated with Wilcoxon signed rank test.Results The detection rates of acute cerebral hemorrhage,arterial aneurysm,AVM and CMBs between CT and multimode MRI were 100%VS 100%,0 VS 13.2%,0 VS 3.8%and 0 VS 28.3%,respectively.The medians of acute cerebral hemorrhage volumes(quartiles)measured by T2WI,DWI,T2*GRE and CT were 5.5(2.0,10.7)mL,7.6(3.1,13.0)mL,8.9(3.3,15.9)mL and 8.6(3.1,15.2)mL,respectively.Differences in hematoma volume measured by T2WI and DWI showed statistical significance compared with CT(P<0.05),while that between T2*GRE and CT was not statistically significant(P>0.05).Conclusion Multimode MRI can provide reliable and comprehensive imaging information for patients with acute cerebral hemorrhage through a single inspection within a short time.
