摘　　要：目的通过分析该院出生的高危足月新生儿的颅脑彩色多普勒超声结果并比较异常者颅脑超声与MRI结果,总结两者在诊断高危足月新生儿颅内疾病的应用价值及差异性。方法收集2017-01~2019-01在该院出生的355例高危足月新生儿的临床资料与出生7 d内的颅脑超声及头颅MRI检查结果。结果颅脑病变阳性者共85例(23.9%),其中颅脑超声诊断室管膜下囊肿66例(18.6%),与头颅MRI的44例(12.4%)比较,差异有统计学意义(P<0.05)。颅脑超声检出脑室内出血与MRI结果相近,差异无统计学意义(P>0.05)。而缺氧缺血性脑病、小脑病变、蛛网膜下腔出血的阳性率MRI高于超声,其中MRI对蛛网膜下腔出血的灵敏度较高,两者比较差异有统计学意义(P<0.05)。结论多普勒超声检查具有安全性、可重复性高等特点,能准确诊断出颅内出血、室管膜下囊肿、缺氧缺血性脑病等高危足月新生儿常见的颅内疾病,但对颅脑边缘及后颅窝的病变分辨率差。Objective To summarize the application value and difference of brain color Doppler ultrasound and magnetic resonance imaging(MRI)in diagnosis of neonatal intracranial diseases by analyzing the results of brain color Doppler ultrasound of high-risk term infants born in our hospital and comparing the results of brain ultrasound and MRI of the abnormal ones.Methods The clinical data of 355 high-risk term infants born in the hospital from January 2017 to January 2019,and the results of the brain ultrasound and MRI examination within 7 days of birth were collected.Results There were 85 cases(23.9%)with positive brain lesions,among them 66 cases(18.6%)with subependymal cyst diagnosed by brain ultrasound,and compared with 44 cases(12.4%)of MRI,the difference was statistically significant(P<0.05).The results of intraventricular hemorrhage detected by craniocerebral ultrasound were similar to those detected by MRI,and the difference was not statistically significant(P>0.05).The positive rates of hypoxic-ischemic encephalopathy,cerebellar lesions and subarachnoid hemorrhage diagnosed by MRI were higher than those diagnosed by craniocerebral ultrasound.Among the three diseases,the sensitivity of MRI in diagnosis of subarachnoid hemorrhage was significantly higher than that of craniocerebral ultrasound(P<0.05).Conclusion Doppler ultrasound is safe and repeatable.It can accurately diagnose intracranial hemorrhage,subependymal cyst,hypoxic-ischemic encephalopathy and other common intracranial diseases of newborns.However,the resolution of the lesions in the edge of brain and posterior cranial fossa is poor.
