| 目的 对比分析Star-容积内插屏气检查（Star-VIBE）序列及常规容积内插屏气检查（VIBE）序列胎儿脑图像质量。方法 对81名妊娠中晚期孕妇分别行Star-VIBE序列（自由呼吸）及常规VIBE序列MR体部扫描，比较2种序列图像中胎儿基底核及脑白质部位SNR及CNR，并比较胎儿脑沟回、基底核及丘脑、脑室系统、小脑及脑干部位2种序列图像质量评分。结果 胎儿基底核及脑白质部位Star-VIBE序列图像的SNR、CNR均高于常规VIBE序列（P均<0.01）。胎儿脑沟回、基底核及丘脑、脑室系统、小脑及脑干部位Star-VIBE序列图像质量评分均高于常规VIBE序列（P均<0.01）。结论 Star-VIBE序列扫描获得的胎儿脑图像质量好于常规VIBE序列，显示胎儿颅内结构更清晰。 |

| Objective To compare image quality of fetal brain between Star-volumetric interpolated breath-hold examination (Star-VIBE) sequence and conventional volumetric interpolated breath-hold examination (VIBE) sequence. Methods Totally 81 pregnant women in middle or late stage of pregnancy underwent Star-VIBE sequence (free breathing) and conventional VIBE sequence scanning. SNR and CNR of images in basal ganglia and white matter were compared between Star-VIBE sequence and VIBE sequence. And the images quality scores of brain sulci and gyrus, basal ganglia and thalamus, ventricle system, cerebellum and brainstem were also compared. Results Both SNR and CNR of Star-VIBE sequence images in basal ganglia and white matter were significantly higher than those of conventional VIBE sequence (all P<0.01). Compared with conventional VIBE sequence, Star-VIBE sequence images had higher quality scores of brain sulci and gyrus, basal ganglia and thalamus, ventricle system, cerebellum and brainstem (all P<0.01). Conclusion The quality of fetal brain images obtained with Star-VIBE sequence scanning is better than conventional VIBE sequence, which may show fetal intracranial structure more clearly. |
