应用多模态MRI成像对探寻微出血发生情况的临床价值分析

Analysis on Clinical Value Multimodal MRI Imaging for Exploring the Occurrence of Microbleeds

目的应用多模态的MRI成像技术,对比在基底节区、丘脑等微出血中各成像序列的应用,选择有效的筛查组合方式,为临床预防治疗微出血提供辅助资料。方法收集本院2017年1月至2019年3月收治的120例神经内科患者的临床资料,对符合研究标准的的76例脑微出血患者MRI图像进行分析,对比常规MRI序列、DWI、T_(2)、T_(1)-VISTA显示微出血情况,分析不同序列扫描系列的一致性。结果在基底节区和丘脑为主要观察区域中,对76例患者的160个区域进行一致性判读。在对其检测中,SWI在92个区域内发现微出血。常规MRI:40个;DWI:56个;T_(2):80个;T_(1)-VISTA:67个。常规MRI序列与SWI的Kappa指数为0.358,一致性较差;DWI、T_(1)-VISTA序列与SWI的结果一致性较好,Kappa指数分别为0.512、0.689;T_(2)序列与SWI的结果一致性高,Kappa指数0.865。结论多模态MRI检查使用不同序列组可有效检出微出血病灶,临床可根据患者个人情况进行序列选择,能为治疗提供可靠依据。

Objective Multimodal MRI imaging techniques were used to compare the application of every imaging sequences in microbleeds of basal ganglia and thalamus,and to select an effective screening combination to provide auxiliary data for clinical prevention and treatment of microbleeds.Methods The clinical data of 120 patients in neurology department admitted to our hospital from January 2017 to March 2019 were collected.The MRI images of 76 patients with cerebral microbleeds meeting the criteria were analyzed.The microbleeds displayed by conventional MRI sequences,DWI,T_(2),and T_(1)-VISTA were compared to analyze the consistency of scan series of different sequences.Results In the basal ganglia and thalamus uesd as the main observation area,160 areas of 76 patients were consistently interpreted.In the detection for them,SWI found microbleeds in 92 areas,conventional MRI found microbleeds in 40,DWI found microbleeds in 56,T_(2)found microbleeds in 80,T_(1)-VISTA found microbleeds in 67.The Kappa index of conventional MRI sequence and SWI was 0.358,and the consistency was poor.The consistency between DWI,T_(1)-VISTA sequences and SWI results.The Kappa index was 0.512 and 0.689,respectively.The consistency of the T_(2)sequence between the SWI results was quite satisfactory.The Kappa index was 0.865.Conclusion Multimodal MRI examination can effectively detect microhemorrhagic lesions using different sequence groups.In clinic,the sequence selection can be based on the patient's individual condition,which can provide a reliable basis for treatment.
