Objective To study the clinical application of ultrasound and CT in the diagnosis of neonatal intracra-nial hemorrhage .Methods 140 cases of our hospital who were diagnosed as neonatal intracranial hemorrhage ( ich) were selected as the research objects , all children were performed with ultrasound , CT and a complete imaging diagnostic data,the results of single ultrasound ,CT diagnosis,ultrasound and CT in the diagnosis were analyzed and compared .Results Among the patients, subependymal hemorrhage , intraventricular hemorrhage , subarachnoid hemorrhage were 3 main bleeding parts of the highest detection rate , and in the detection rate of subependymal hemorrhage on ultrasonic CT was significantly higher than that in intraventricular hemorrhage , subarachnoid hemorrhage , parenchymal hemorrhage , subdural hemorrhage detection rate were superior to ultrasound,the differences were statistically significant (P<0.05).The diagnostic accuracy of computed tomography ( CT) , ultrasound and CT in combination with ultrasound were 72.9%, 74.3% and 92.9%respectively,the diagnostic accuracy of CT in combination with ultrasound was significantly higher than that of the two imaging methods alone,there was statistically difference (P<0.05).Conclusion Ultrasound and computed tomography( CT) is an effective approach to clinical diagnosis of neonatal intracranial hemorrhage ,each has its own advantages and disadvantages .Joint application of them can get the best diagnosis results in the process of diagnosis to provide effective basis for the treatment in children .%目的：研究探讨超声、 CT诊断新生儿颅内出血的临床应用价值。方法选取医院收治的140例确诊为颅内出血新生儿作为研究对象，所有患儿均实施超声、 CT诊断并有完整的影像学诊断资料，分别对单独的超声、 CT诊断结果，超声与CT联合诊断结果进行分析和比较。结果140例患者中，室管膜下出血、脑室内出血、蛛网膜下腔出血分别是检出率最高的3个出血部位，且在室管膜下出血的检出率上超声显著高于CT，而在脑室内出血、蛛网膜下腔出血、脑实质出血以及硬膜下出血的检出率上，则有CT优于超声的情况，室管膜下出血和脑室内出血比较均有统计学意义（ P ＜0．05）。 CT、超声以及 CT 联合超声3种诊断方法下的诊断正确率分别为72．9％、74．3％和92．9％， CT联合超声诊断的准确率显著高于2种影像学方法单独诊断的结果，比较差异有统计学意义（ P＜0．05）。结论超声和CT都是临床诊断新生儿颅内出血的有效方法，二者各有优缺点，将其联合应用，可以在诊断过程中获得最佳的诊断结果，为患儿的治疗提供有效依据。
