| 目的 探讨衡阳地区缺血性脑卒中患者脑微出血多模态磁共振成像诊断价值。方法回顾性分析131例初步诊断为缺血性脑卒中患者头颅多模态磁共振检查资料,以磁敏感加权成像序列为检出微出血的标准,对基底节区、丘脑微出血进行分级评价。结果与磁敏感成像序列对比,常规MRI序列、磁共振弥散成像、T2*序列、3D-VISTA序列对缺血性脑卒中伴基底节区、丘脑脑内微出血的检出的Kappa值分别为0.366,0.521,0.859,0.673,其中T2*序列与磁敏感加权成像序列检出情况一致性较好。结论多模态MRI成像能够有效探寻微出血发生情况,优化多模态MRI成像序列的筛查可以为临床预防、干预缺血性脑卒中患者出现脑出血提供有力的支持。 |

| Objective To investigate the application and value of the muti-modality MRI in the detecting the cerebral microbleeds (CMBs) in Hengyang City.Methods131 cases of patients,who were diagnosed with ischemic stroke and underwent muti-modality MRI,were retrospectively analyzed and carefully observed.The susceptibility weighted imaging(SWI) sequence were applied as Golden Standard.ResultsThe Kappa value,which is the sequences of conventional MRI,DWI,T2*sequence,3D-VISTA,was 0.366,0.521,0.859,0.673.It means that the T2* and 3D-VISTA show good consistence with the SWI.ConclusionsThe muti-modality magnetic resonance imaging can effectively detect CMBs If making full use of the muti-modality MRI,it can provide a strong protocol for the prevention and intervention of the cerebral hemorrhage of the ischemic stroke patients with CMBs. |
