磁敏感加权成像在新生儿颅脑损伤诊断中的应用价值
Application value of susceptibility-weighted imaging for neonatal craniocerebral injury
摘要
Abstract
Objective:To evaluate the value of susceptibility weighted imaging(SWI)in the diagnosis and differential diagnosis of neonatal craniocerebral injury.Materials and Methods:A retrospective collection of 900 neonates suspected of intracranial hemorrhage(ICH)after cranial ultrasound screening in Shanxi Children's Hospital was completed with conventional MRI and SWI.The chi-square test was used to compare the detection rates of conventional MRI and SWI for different hemorrhage sites.The chi-square test was used to evaluate the differences in different sites of ICH in preterm and term infants.Results:(1)SWI has a higher detection rate of neonatal ICH than conventional MRI(24.0%vs.19.8%,P<0.05);(2)For hemorrhage in the lateral ventricles,cerebral cortex,cerebellar hemispheres,and subdural/epidural hemorrhages,SWI detects a greater number and extent of lesions than conventional MRI(P<0.05);(3)The detection rate of hemorrhage lesions in germinal matrix and lateral compartment was higher in preterm infants than term infants,and the detection rate of hemorrhage lesions in subarachnoid space was lower than in term infants(P<0.05).Conclusions:SWI is somewhat superior to conventional MRI in detecting neonatal ICH and identifying punctate white matter lesion and microhemorrhagic lesions.Therefore,it is recommended that conventional MRI combined with SWI sequences should be used for comprehensive diagnosis in order to improve the efficacy of detecting ICH lesions and provide an imaging basis for clinical diagnosis and treatment.关键词
