目的 观察超声与MSCT在诊断早 产儿颅内出血(ICH)中的应用价值。方法 对42例疑似ICH早产儿的临床资料进行回 顾性分析，所有患儿均接受超声和MSCT 检查，比较2种方法的诊断结果差异。根 据新生儿ICH诊断标准，评估超声与MSCT 对早产儿ICH的诊断效能。结果 超声对 IVH、SAH、SDH检出率及诊断早产儿ICH的 灵敏度、特异度、准确度、阳性预测值、 阴性预测值与MSCT比较差异无统计学意义 (P＞0.05)，MSCT与综合诊断一致性高于 超声。超声、MSCT在诊断早产儿ICH=差异 无统计学意义(P＞0.05)。结论 超声对早 产儿IVH检出率较高，且具有无辐射、便 捷等优势，MSCT在诊断SDH、SAH等方面较 超声更具优势，2种方法各有优劣，联合 应用对及时准确诊断早产儿ICH有一定帮 助。

Objective To observe the application value of ultrasound and MSCT in diagnosing intracranial hemorrhage (ICH) in preterm infants. Methods The clinical data of 42 suspected ICH preterm infants were analyzed retrospectively. All patients were given ultrasound and MSCT. The diagnostic results were compared between the two methods. According to the diagnostic criteria for neonatal ICH, the diagnostic efficacy of ultrasound and MSCT were evaluated in ICH preterm infants. Results There was no significantly difference in the detection rates of IVH, SAH and SDH, and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of ICH preterm infants between ultrasound and MSCT (P>0.05), and the consistency of MSCT and comprehensive diagnosis was higher than that of ultrasound. The correlation of ultrasound and MSCT in diagnosing ICH preterm infants was statistically significant (P<0.05). The dominance was not statistically significant (P>0.05). Conclusion Preterm infants has high detection rate of IVH by ultrasound, and ultrasound has advantages of no radiation anf convenience. MSCT is superior to ultrasound in diagnosing SDH and SAH. The two methods have their own advantages and disadvantages, and the combined application can help the diagnosis of ICH in preterm infants timely and accurately.
