摘　　要：目的探讨临床诊断新生儿低血糖脑损伤应用电子计算机断层扫描(CT)、磁共振成像(MRI)应用价值。方法择取我院2021年3月至2022年3月低血糖脑损伤患儿20例,所有患儿均需实施CT与MRI检查,分别为CT组与MRI组,统计两组低血糖脑损伤检出率、漏诊率以及误诊率,同时观察两组不同发病时间、是否存在症状表现在本组低血糖脑损伤患儿病例中的占比率,观察两组影像学特征。结果MRI组检出率为85.00%较CT组50.00%更高,差异有统计学意义(P<0.05),MRI组误诊率、漏诊率分别为5.00%、10.00%,较CT组25.00%、25.00%更低,差异无统计学意义(P>0.05);MRI组发病时间≥12h者在本组低血糖脑损伤患儿病例中占比为88.24%,存在症状表现者占比率为88.24%,CT组发病时间≥12h者在本组低血糖脑损伤患儿病例中占比为60.00%,存在症状表现者占比率为50.00%;是否存在症状表现的病例在CT、MRI两种影像学诊断结果占比有一定的影响,差异有统计学意义(P<0.05),但不同发病时间病例则无较大影响,差异无统计学意义(P>0.05)。结论临床诊断新生儿低血糖脑损伤应用电子计算机断层扫描(CT)、磁共振成像(MRI)均具有一定的应用价值,相对CT而言,MRI可促进新生儿低血糖脑损伤检出率提升,但仍存在一定的误诊、漏诊风险,因此可采取CT联合MRI的方式对新生儿低血糖脑损伤加以诊断,以此提升诊断结果精准性,有效改善患儿预后。Objective To investigate the clinical diagnosis of neonatal hypoglycemic brain injury using electron computed tomography(CT)and magnetic resonance imaging(MRI).Methods a total of 20 children with hypoglycemic brain injury were selected from our hospital from March 2021 to March 2022,and all children were required to implement CT and MRI,respectively,for CT group versus MRI group,and the statistical detection rate,missed diagnosis rate,and misdiagnosis rate of hypoglycemic brain injury in the two groups were calculated,while the incidence of different onset times,presence or absence of symptoms in the cases of hypoglycemic brain injury in the two groups were observed,and the imaging characteristics of the two groups were observed.Results the detection rate of 85.00%in the MRI group was higher than that of 50.00%in the CT group,with a significant difference(P<0.05),and the misdiagnosis rate and missed diagnosis rate of 5.00%,10.00%,respectively,in the MRI group was lower than that of 25.00%,25.00%,respectively,with no significant difference(P>0.05);the proportion of children with hypoglycemic brain injury onset≥12 h in the MRI group was 88.24%,the proportion of those with symptomatic presentation was 88.24%,and the proportion of children with hypoglycemic brain injury onset≥12 h in the CT group was 60.00%,the proportion of those with symptomatic presentation was 50.00%;the proportion of cases with or without the presence of symptomatic findings on two imaging diagnostic modalities,CT and MRI,was significantly different(P<0.05),but the proportion of cases with different onset times was not significantly different(P>0.05).Conclusion clinical diagnosis of neonatal hypoglycemic brain injury using electron computed tomography(CT),magnetic resonance imaging(MRI)are all of great value,relative to CT,MRI can promote the detection rate of neonatal hypoglycemic brain injury,but there is still a certain risk of misdiagnosis and missed diagnosis,therefore CT combined with MRI can be adopted to diagnose neonatal hypoglycemi
