Diagnostic value of SWI sequence scan for intracranial hemorrhage in neonates with hypoxic ischemic encephalopathy
Objective To explore the diagnostic value of susceptibility weighted imaging(SWI)sequence scan for intracranial hemorrhage in neonates with hypoxic ischemic encephalopathy(HIE).Methods A total of 144 children with HIE complicated with intracranial hemorrhage preliminarily diagnosed in our hospital from June 2018 to April 2021 were selected as the research objects,and all of them underwent MRI examination.The detection of intracranial hemorrhage in HIE children by MRI routine sequence and SWI sequence were compared;the number of hemorrhagic lesions detected in different parts by MRI routine sequence and SWI sequence were compared.Results Among 144 cases preliminarily dignosed with HIE complicated with intracranial hemorrhage,83 cases of intracranial hemorrhage were detected by T1-weighted imaging(T1WI)sequence,and the detection rate was 57.64%(83/144);59 cases of intracranial hemorrhage were detected by T2-weighted imaging(T2WI)sequence,with a detection rate of 40.97%(59/144);32 cases of intracranial hemorrhage were detected by fluid-attenuated inversion recovery(FLAIR)sequence,and the detection rate was 22.22%(32/144);119 cases of intracranial hemorrhage were detected by SWI sequence,and the detection rate was 82.64%(119/144).The detection rate of intracranial hemorrhage in T1WI sequence was higher than that in T2WI sequence and FLAIR sequence,and the differences were statistically significant(P<0.05);the detection rate of intracranial hemorrhage in T2WI sequence was higher than that in FLAIR sequence,and the difference was statistically significant(P<0.001);the detection rate of intracranial hemorrhage in SWI sequence was higher than that in T1WI sequence,T2WI sequence and FLAIR sequence,and the differences were statistically significant(P<0.001).The number of hemorrhagic lesions detected by T1WI sequence was significantly higher than that of T2WI sequence and FLAIR sequence,and the differences were statistically significant(P<0.001);the number of hemorrhagic lesions detected by T2WI sequence was significantly higher than that of FLAIR sequence,and the difference was statistically significant(P<0.001);the number of hemorrhagic lesions detected by SWI sequence was significantly higher than that of T1WI sequence,T2WI sequence and FLAIR sequence,and the differences were statistically significant(P<0.001).Conclusion SWI sequence scan has a high diagnostic value for children with HIE complicated with intracranial hemorrhage,it can clearly show the location and number of lesions,which is helpful for clinicians to observe and judge,and then implement targeted treatment.
