| 目的 测量中晚孕期正常胎儿大脑大静脉（VOG）管径并探讨其临床价值。方法 选取行MR检查的孕中晚期正常胎儿86胎，观察单次激发快速自旋回波（SS-FSE）序列、快速成像稳态采集（FIESTA）序列、DWI序列、快速反转恢复运动抑制（FIRM）序列下VOG及脑静脉窦的成像清晰度，获得“优势”序列，以此测量VOG管径，对所得测量值与孕周行Pearson相关分析。结果 SS-FSE序列对VOG及静脉窦的成像清晰度优于其他序列（P<0.05），以此序列测量胎儿VOG横径为（2.92±；0.35）mm，VOG横径随孕周的增加而增大，与孕周呈正相关（r=0.762，P<0.05），线性回归方程为Y=0.799+0.070X（P<0.05）。结论 SS-FSE序列是显示胎儿VOG及静脉窦的一种可靠的、有效的检查方法；对正常胎儿VOG管径的测量及相关研究可为临床提供一定的参考依据。 |

| Objective To measure the diameter of the fetal vein of Galen (VOG) in middle and late pregnancy, and to explore its clinical value. Methods A total of 86 cases of normal fetuses in middle and late pregnancy who underwent MR examination with the single shot-fast spin echo (SS-FSE), fast imaging employing steady-state acquisition (FIESTA), DWI and fast inversion recovery motion insensitive (FIRM) sequence were selected. The image quality of VOG and cerebral venous sinus in each sequence were observed and compared. The advantage sequence was used in the measurement of VOG diameter. The correlation between the VOG diameter and gestational age was analyzed by Pearson correlation. Results SS-FSE sequence was superior to other conventional MR sequences on the image quality of VOG and cerebral venous sinus (P<0.05); the normal fetal VOG diameter was (2.92±0.35)mm. The diameter of VOG was positively correlated with gestational age (r=0.762, P<0.05), the linearly equation was Y=0.799+0.070X (P<0.05). Conclusion SS-FSE sequence is a reliable, effective examination technique, which can clearly display fetal VOG and venous sinus. The measurement and related research of normal fetal VOG may provide reference for clinical practice. |
