【摘要】：目的探讨经颅二维及三维超声VOCAL技术观察新生儿海马结构形态特征及其与矫正胎龄的关系。资料与方法回顾性分析2013年6月-2014年12月于福建医科大学附属第二医院超声科出生的183例新生儿矫正胎龄32~43周单胎新生儿海马结构的形态特征,经颅脑前囟矢状面扫描至旁矢状面侧脑室中央部-后角层面,并测量其长径、宽径、面积、周长,运用三维超声VOCAL技术测量其体积。采用相关分析评价各测量参数与矫正胎龄间的相关性。结果新生儿的海马结构显示率为100%,形态呈"如意棒"形,矫正胎龄与海马各测量参数均呈正相关(长径:r=0.475,P0.01;宽径:r=0.234,P0.01;周长:r=0.540,P0.01;面积:r=0.428,P0.01;体积:r=0.537,P0.01)。结论经颅脑超声可作为观察测量新生儿海马的有效技术手段,且海马径线与矫正胎龄具有一定的相关性。
[Abstract]:Objective to investigate the morphological characteristics of hippocampal formation and its relationship with corrected gestational age by transcranial two-dimensional and three-dimensional ultrasound VOCAL. Data and methods retrospective analysis was made from June 2013 to December 2014. Morphological features of hippocampal structure of 183 newborns born in the Department of Ultrasonography of the second affiliated Hospital of Fujian Medical University. The sagittal plane of anterior fontanelle of brain was scanned to the central part and posterior horn of lateral lateral ventricle of lateral sagittal plane, and its length, width, area and circumference were measured. Three-dimensional ultrasound VOCAL technique was used to measure its volume. Correlation analysis was used to evaluate the correlation between the measured parameters and corrected gestational age. Results the display rate of hippocampal structure in neonates was 100%. The corrected gestational age was positively correlated with the hippocampal parameters (long diameter: 0.475U, P 0.01). Wide diameter: 0.234% P0.01; The circumference is 0. 540. P. 01. Area: 0. 428. P. 01. Conclusion Transcraniocerebral ultrasound can be used as an effective technique to measure the hippocampus of newborns, and there is a certain correlation between the diameter of hippocampus and the corrected gestational age.
