摘要
目的应用超声与MRI对早产儿颅内出血行同期对照检查,比较两种方法的诊断价值。方法对335例临床高度疑似颅内出血的早产儿行颅脑超声及MRI检查,对比分析两种方法的诊断结果。根据新生儿颅内出血诊断标准,计算超声与MRI的诊断敏感性、特异性及准确率。结果颅脑超声和MRI诊断Ⅰ级脑室出血、硬膜下腔出血及蛛网膜下腔出血比较差异均有统计学意义(χ~2=4.17、5.14、8.10,均P<0.05),诊断其他类型脑出血比较差异均无统计学意义。超声和MRI诊断Ⅰ级脑室出血的敏感性、特异性及准确率分别为100%、100%、100%和94%、100%、94%,诊断硬膜下腔出血的敏感性、特异性及准确率分别为78%、100%、80%和100%、100%、100%,诊断蛛网膜下腔出血的敏感性、特异性及准确率分别为77%、100%、79%和100%、100%、100%。结论超声与MRI对不同类型早产儿颅内出血的诊断各有优势,临床对高危新生儿,特别是早产儿可先行超声筛查,需进一步明确诊断时再行MRI检查。
Objective To examine the intracranical hemorrhage of premature neonates by ultrasound and MRI,and compare the diagnostic value of two methods. Methods Three hundreds and thirty-one premature neonates suspected to be intraeranical hemorrhage were examined by ultrasound and MRI. The diagnostic results were compared and analyzed. According to the criteria for the diagnosis of neonatal intracranial hemorrhage,the diagnostic sensitivity,specificity and accuracy of ultrasound and MR1 were calculated. Results Between two methods,the results of the first level of intraventricular hemorrhage, subdural hematoma and subarachnoid hemorrhage had significant differences （χ2=4.17,5.14,8.10, all P〈0.05 ）, while the results of other types of cerebral hemorrhage had no significant difference. The sensitivity, specificity and accuracy of ultrasound in diagnosis of the first level of intraventricular hemorrhage were all 100% ,while the results of MRI were 94% , 100% ,94% , respectively. The results of ultrasound in diagnosis of subdural hematoma were 78%, 100%, 80%, respectively while the results of MRI were all 100%. The results of ultrasound in diagnosis of subarachnoid hemorrhage were 77%, 100% ,79% ,respectively, while the results of MRI were all 100%. Conclusion There are advantages and disadvantages in diagnosis of intracranial hemorrhage of premature neonates by ultrasound and MRI. With respect to high risk neonates,ultrasound can be firstly used particularly for premature neonates and MRI for further examination.
