摘　　要：目的初步探究颅脑超声与MRI检查应用于新生儿颅内出血诊断中的临床价值。方法选取皖北煤电集团总医院2014年9月至2018年12月收治的90例颅内出血的新生儿患者。分析其影像学征象,对比经颅脑超声和MRI检查对新生儿颅内出血的诊断灵敏度和特异度。结果颅脑超声对新生儿颅内出血的诊断灵敏度及特异度(87.78%、82.22%)与MRI检查(90.00%、85.56%)比较无明显差异(P>0.05)。超声可见一侧或双侧脑室内可见强回声光团,表现为脉络丛增宽,回声增强,边缘不完整,形态不规则与脉络丛分界较清楚;脑实质内出现局灶性团块状强回声。MRI可见T1WI表现为血肿周边高信号,中心等信号,血肿周围的水肿呈低信号;血肿在T2WI上呈低信号;T1WI和T2WI上均为高信号;血肿充分吸收,T1和T2表现为斑点样不均匀略低信号影。结论采用颅脑超声检查和MRI检查均可有效地显示新生儿颅内出血的影像学特点,两种检查对不同类型的新生儿颅内出血的诊断均具有较高的价值。Objective To explore the clinical value of craniocerebral ultrasound and MRI in the diagnosis of neonatal intracranial hemorrhage.Methods 90 neonatal patients with intracranial hemorrhage admitted to our hospital from September 2014 to December 2018 were selected.The imaging signs were analyzed The sensitivity and specificity of craniocerebral ultrasound and MRI in the diagnosis of neonatal intracranial hemorrhage were compared.Results There was no significant difference in the sensitivity and specificity between craniocerebral ultrasound (87.78%,82.22%) and MRI examination (90.00%,85.56%) in the diagnosis of neonatal intracranial hemorrhage (P>0.05).The images of craniocerebral ultrasound can be seen with light mass with strong echo in one or both sides of the ventricle,showing widening of the choroid plexus,enhanced echo,incomplete edges and irregular shapes.And the boundary with choroid plexus was clearer.Focal strong echoes like mass appeared in the brain parenchyma.MRI images showed that T1WI showed high signal around the hematoma and showed equal signal in the center of hematoma.The edema around the hematoma showed low signal.Hematoma showed low signal on T2WI,showed high signal on T1WI and T2WI.The hematoma was fully absorbed,and T1 and T2 showed slightly low and uneven signal shadow like spot.Conclusion Both craniocerebral ultrasound and MRI can effectively show the imaging features of neonatal intracranial hemorrhage.They have high value in the diagnosis of different types of neonatal intracranial hemorrhage.
