摘要
目的探讨三维容积超声与磁共振(MRI)成像技术在诊断新生儿颅内出血中的应用效果。方法将南昌天使妇产医院2017年9月至2019年12月收治的62例颅内出血新生儿作为研究对象,收集其临床资料和三维容积超声、MRI影像学资料,观察两种检查方法的影像学表现,并对比其在新生儿颅内出血中的诊断结果。结果三维容积超声检查显示有54例发生颅内出血,超声表现为颅内不同部位和不同程度的强回声改变,其诊断新生儿颅内出血准确率为87.10%。MRI检查显示有53例发生颅内出血,影像学表现为颅内不同部位T_(1)WI、T_(2)WI信号的异常表现,其诊断新生儿颅内出血准确率为85.48%。三维容积超声诊断室管膜下出血优于MRI(P<0.05),诊断其他颅内出血部位与MRI无显著差异(P>0.05)。结论三维容积超声与MRI成像技术在新生儿颅内出血诊断中均有一定价值,且三维容积超声在诊断室管膜下出血方面优于MRI。
Objective To investigate the effect of three dimensional volume ultrasound and magnetic resonance(MRI)imaging in the diagnosis of neonatal intracranial hemorrhage.Methods From September 2017 to December 2019,62 neonates with intracranial hemorrhage were treated in Nanchang Angel Obstetrics and Gynecology Hospital.The clinical data,three-dimensional volume ultrasound and MRI imaging data were collected,the imaging findings of the two methods were observed,and the diagnostic results of intracranial hemorrhage in neonates were compared.Results Three dimensional volume ultrasound showed intracranial hemorrhage in 54 cases.Ultrasound showed strong echo changes in different parts and degrees of the brain.The accuracy of intracranial hemorrhage in severed neonates was that 53 cases of intracranial hemorrhage occurred on 87.10%.MRI.The imaging findings showed T_(1)WI in different parts of the brain and the abnormal signal on T_(2)WI.The accuracy of diagnosis of intracranial hemorrhage in neonates was 85.48%.Three-dimensional volume ultrasound was superior to MRI in the diagnosis of subependymal hemorrhage(P<0.05),but there was no significant difference in the diagnosis of other intracranial hemorrhage sites and MRI(P>0.05).Conclusion Three dimensional volume ultrasound and MRI imaging are valuable in the diagnosis of neonatal intracranial hemorrhage,and three dimensional volume ultrasound is superior to MR in the diagnosis of subependymal hemorrhage.
