【摘要】：目的评价超声和MRI测量胎儿侧脑室宽度和诊断侧脑室增宽的一致性。方法回顾性分析200胎胎儿头颅轴位声像图和冠状位MRI测量的双侧侧脑室宽度,评价两种检查方法测量的一致性[采用组内相关系数(ICC)]和诊断侧脑室增宽的一致性(采用κ系数),评价不同MRI医师间测量侧脑室宽度的一致性(采用ICC)。结果超声和MRI测量侧脑室1(宽度较宽的侧脑室)、侧脑室2(宽度较窄的侧脑室)宽度的一致性很好(ICC=0.98、0.96),超声和MRI诊断侧脑室增宽的一致性很好(κ0.8)。2名MRI医师测量侧脑室1、侧脑室2宽度的一致性很好(ICC=0.999、0.997)。结论超声与MRI测量侧脑室宽度和诊断侧脑室增宽具有很好的一致性。
[Abstract]:Objective to evaluate the consistency between fetal lateral ventricular width and lateral ventricular width measured by ultrasound and MRI. Methods the bilateral ventricular widths measured by axial sonography and coronal MRI were analyzed retrospectively. Evaluation of consistency between two inspection methods. [The correlation coefficient (ICCC) in the group was consistent with that in the diagnosis of lateral ventricular widening (魏 coefficient). To evaluate the consistency of measuring the width of lateral ventricle between different MRI physicians (ICC). Results Ultrasound and MRI were used to measure the lateral ventricle 1 (lateral ventricle with wide width). The width of lateral ventricle 2 (lateral ventricle with narrower width) was consistent well with that of ICC 0.98 (0.96). There was a good consistency between ultrasound and MRI in the diagnosis of lateral ventricular widening (魏 0.8.2 MRI physicians measured the lateral ventricle 1, and the lateral ventricle 2 width was well consistent with ICC0.999). Conclusion Ultrasound is in good agreement with MRI in measuring the width of lateral ventricle and in diagnosing lateral ventricular widening.

【正文快照】： 侧脑室增宽是胎儿产前诊断常见的颅内异常[1],目前临床定义侧脑室增宽的标准为侧脑室宽度≥10mm[2]。传统测量胎儿侧脑室宽度的方法是在超声轴位平面上测量侧脑室三角区的横径[3]。近年来MRI逐渐用于胎儿神经系统成像,有广泛的产前诊断适应证[4]。目前MRI测量侧脑室宽度推荐在
