Comparative Study of DWI and SWI Combined with Conventional MRI Sequence and Ultrasound in HIE Diagnosis
Objective Exploring the application value of conventional magnetic resonance imaging sequences combined with diffusion-weighted imaging(DWI)and magnetic sensitivity weighted imaging(SWI)in the diagnosis of neonatal hypoxic-ischemic encephalopathy,and comparing them with ultrasound diagnosis of neonatal hypoxic-ischemic encephalopathy.Methods A retrospectively analyse was conducted on 56 children clinically diagnosed with HIE,and Number of detected lesions by multimodal magnetic resonance imaging and ultrasound examination of the brain were compared with each other.Results The number of cases of subarachnoidal/subdural hemorrhage,parenchymal hemorrhage,and cerebral infarction/neuronal necrosis was more than that of ultrasound,and the difference has significant statistical significance(P＜0.05).The number of cases of subependymal/intraventricular hemorrhage was less than that of ultrasound by multimodal magnetic resonance imaging of the brain,and the difference has significant statistical significance(P＜0.05).There was no significant difference in the number of cases of periventricular leukomalacia/cystic degeneration on multimodal magnetic resonance imaging of the brain compared with ultrasound.Conclusion Cranial multimodal magnetic resonance imaging has certain advantages over ultrasound in the diagnosis of HIE,and the two are complementary.
