| 摘要：目的 应用超声与MIR对早产儿颅内出血进行同期对照检查，比较两种方法对早产儿颅内出血的诊断价值。方法 对335例临床高度疑似颅内出血的早产儿，同时进行颅脑超声及MRI检查，对两种诊断结果进行分析比较。结果335例颅内出血中，超声诊断符合315例，不符合20例；MRI诊断符合323例，不符合12例。两种检查方法在诊断Ⅰ级脑室出血、硬模下腔出血、蛛网膜下腔出血中均有统计学意义（P≤0.05），对于其他类型脑出血均无统计学意义（P＞0.05）。灵敏度、特异度、准确性方面：Ⅰ级脑室出血超声检查均为100%，MRI检查分别为94%、100%、94%；硬模下腔出血超声检查分别为78%、100%、80%，MRI检查均为100%；蛛网膜下腔出血超声检查分别为77%、100%、79%，MRI检查均为100%。结论 超声与MRI对诊断不同的早产儿颅内出血各有利弊，临床对高危新生儿，特别是早产儿可先行超声检查，需进一步明确诊断时，再行MRI检查。 |

| Abstract: Objective To examine the intracranical hemorrhage of newborns using ultrasound and MRI and compare the diagnosis value between the two test methods. Methods 335 newborns suspected to be intracranical hemorrhage were examined by both ultrasound and MRI. The diagnosis results were compared and analyzed. Results Of all the cases, the ultrasound make 315 right diagnoses and 20 wrong diagnosis; while the MRI make 323 right diagnoses and 12 wrong diagnoses. Between the two test methods, The results of the first level of intraventricular hemorrhage, subdural hematoma and subarachnoid hemorrhage have significant differences (P≤0.05); while the results of other types of cerebral hemorrhage are not statistically different (P＞0.05). Considering the respects of sensitivity, specificity and accuracy, the results of ultrasound were 100% in the case of the first level of intraventricular hemorrhage; while the results of MRI were 94%、100%、94% respectively. The results of ultrasound were respectively 78%、100%、80% in the case of subdural hematoma; while the results of MRI were all 100%. The results of ultrasound were respectively 77%、100%、79% in the case of subarachnoid hemorrhage; while the results of MRI were all 100%. Conclusion There are advantages and disadvantages in the the diagnosis of intracranial hemorrhage of newborns using ultrasound and MRI. With respect to high risk infants, ultrasound can be firstly used particularly for premature infant and MRI for further examination. |
