目的探讨颅脑超声对高危新生儿脑损伤的诊断价值。方法对611例高危新生儿做颅脑超声检查,发现异常者同时以CT对照检查。结果发现异常101例(16.53%),其中脑室周围-脑室内出血59例(58.42%),缺血缺氧性脑损伤32例(31.68%)。结论颅脑超声对脑中央部位病变,如脑室系统出血有更高的准确性和敏感性。 Objective To investigate the diagnostic value of brain ultrasound in brain injury in high-risk neonates. Methods Sixty-one hundred and seventy-one high-risk neonates were examined by CT, and abnormalities were detected by CT. The results showed abnormalities in 101 cases (16.53%), of which 59 cases (58.42%) had periventricular-intraventricular hemorrhage and 32 cases (31.68%) had hypoxic-ischemic brain damage. Conclusion Intracranial ultrasound in the central part of the brain lesions, such as intraventricular hemorrhage with higher accuracy and sensitivity.
