MR常规序列联合SWI、DWI在新生儿颅内出血疾病中的诊断价值

Diagnostic Value of MR Routine Sequences Combined with SWI and DWI in Intracranial Hemorrhage in Neonates

目的探究MR常规序列同步使用磁敏感加权成像(SWI)和扩散加权成像(DWI)两种技术手段对于新生儿颅内出血的临床诊疗价值。方法选取100名经MR确诊为头颅内部出血的新生儿作为研究对象,MRI扫描包括常规序列(T;WI、T;WI)和SWI、DWI两种功能成像技术手段,对比不同序列对应的影像学特征,同时对相关数据进行整合分析,DWI序列在该过程中主要发挥补充作用。结果在选入研究的100名新生儿患者中,T;WI检测出颅内出血患儿85名,T;WI检测出54名,SWI检出有79名;T;WI、T;WI检查出患儿颅内出血病灶的个数分别是104个和85个,而SWI检测出颅内出血灶有144个,该检查结果一定程度大于常规序列检测结果,两者比较存在统计学差异。结论SWI在检测颅内出血灶方面一定程度优于常规序列,而DWI可借助于磁化率伪影完成对微出血灶的辅助检出工作。将常规MRI和SWI、DWI同步使用会提升新生儿颅内出血灶的诊断能效,为后续的临床治疗提供影像学支撑。

Objective To explore the diagnostic value of MR routine sequences in combination with sensitivity weighted imaging(SWI)and the diffusion weighted imaging(DWI)in the diagnosis and treatment value of neonatal intracranial hemorrhage.Methods 100 neonates with intracerebral hemorrhage diagnosed by MR including conventional MRI(T;WI,T;WI)and functional imaging SWI and DWI were selected as the study objects.The imaging signs of each sequence were compared and the results were analyzed statistically,DWI sequence complemented.Results Among the 100 neonates with intracranial hemorrhage,85 cases were detected by T;WI,54 cases were detected by T;WI,while 79 cases were confirmed by SWI sequence;104 and 85 cases were found by T;WI and T;WI,and 144 cases of intracranial hemorrhage were detected by SWI,which was in some degree more than the conventional sequences.Conclusion SWI has advantage over conventional MRI in the detection of intracranial hemorrhage lesions,while DWI can use magnetic susceptibility artifacts to help detect microbleeds.The simultaneous use of conventional MRI,SWI and DWI will improve the diagnostic efficiency of neonatal intracranial hemorrhage foci and provide imaging support for subsequent clinical treatment.
