摘要
目的分析小儿颅脑超声与MRI检查对早期高危儿童脑损伤的诊断价值。方法随机选取我院儿科2018年1月至2018年12月收治的早期高危儿童脑损伤患儿110例,对其使用小儿颅脑超声与MRI进行诊断。比较两种影像学诊断早期高危儿童脑损伤部位及类型,分析小儿颅脑超声与MRI影像学特点。结果110例患儿临床表现出一些非特异性的症状及体征,包括反应低下101例,哭声较正常水平改变84例,自主活动少或肌张力低下81例,继发性呼吸暂停51例,原始反射减弱或消失87例,进食困难41例。以上非特异性临床症状可单独出现也可多个合并出现。MRI总体检出率显著高于颅脑超声(P<0.05)。MRI检出颅内出血率高于颅脑超声(P<0.05)。颅脑超声发现患儿双侧大脑半球都出现中低回声或略低回声。脑沟回稀疏,脑回宽且脑沟浅,脑叶分化不完整,岛叶未见分化呈片状。所有患儿双侧脑室前角细而弯曲,第三脑室呈缝隙状,双侧侧脑室周围白质回声均匀一致增强且回声低于脉络丛。颅脑超声发现脉络丛形态欠规整且回声稍增强4例,将其诊断为脑出血,后经MRI检查提示正常;颅脑超声提示5例患儿侧脑室前角白质回声稍增强,诊断局部脑白质损伤,后经MR检查提示正常。MRI发现110例患儿片状TI信号长T2信号异常,点状及斑片状信号高。结论小儿颅脑超声与MRI都能作为早期高危儿童脑损伤重要影像学方法。而MRI在检出病变部位及反映疾病类型方面优于经颅超声,建议联合应用。
Objective To investigate the clinical application value of cerebral ultrasound and routine MRI in diagnosising brain injury in high-risk neonates.Methods From January 2018 to December 2018,110 cases of early high-risk children with brain injury admitted to the department of pediatrics of our hospital were randomly selected,and all the children received the cerebral ultrasound and routine MRI.The location and type of brain injury in early high-risk children presented by two imaging methods were compared,and the imaging characteristics were also summarized.Results 110 children showed some non-specific clinical symptoms and signs,including 101 cases of hyporesponsiveness,84 cases of crying changes,80 cases of secondary apnea,81 cases of the low autonomic activity or low muscle tension,51 cases of secondary apnea,87 cases of primary reflex weakening or disappearing,41 cases of eating difficulties.The overall detection rate of MRI was significantly higher than that of cerebral ultrasound(P<0.05).The detection rate of intracranial hemorrhage by MRI was higher than that by cerebral ultrasound(P<0.05).Craniocerebral ultrasound showed that both hemispheres were hypoechoic or slightly hypoechoic.The cerebral sulcus was sparse,the gyrus was wide and the sulcus was shallow.The anterior horn of the bilateral ventricle was thin and curved in all the children,and the third ventricle presented a gap shape.The echo of white matter around bilateral ventricles was uniformly enhanced and the echo was lower than the choroid plexus.Cerebral ultrasonography found 4 cases with irregular choroid plexus with slightly enhanced echo,which was diagnosed as cerebral hemorrhage.MRI examination indicated that it was normal.Craniocerebral ultrasound showed slight enhancement of white matter echo in the anterior horn of lateral ventricle in 5 cases,and local white matter injury was diagnosed.MRI examination indicated that it was normal.MRI showed abnormal signals in 110 children.Conclusion both cerebral ultrasound and routine MRI can be used to d
