摘　　要：目的:探讨BSSFP序列三时相扫描技术在胎儿心血管系统磁共振检查中的应用价值。材料与方法:回顾性分析38例经产前超声提示未见异常的胎儿心血管系统磁共振图像,均行BSSFP序列单时相及三时相扫描。由三位MRI医师分析两组图像中四腔心、主动脉弓层面解剖结构,并对两组图像进行评分。结果:38例图像中,对主动脉弓层面的显示,BSSFP序列单时相和三时相扫描评分差异有统计学意义(P=0.048);对四腔心层面的显示,两者评分差异无统计学意义(P=0.620)。结论:BSSFP序列三时相扫描技术有助于提高胎儿心血管系统图像质量,尤其是主动脉弓层面,能更好显示胎儿心外大血管解剖结构,为胎儿心血管结构的显示提供了一种新的成像思路。Objective:To explore the application value of BSSFP sequence with three-phase in fetal cardiovascular MRI.Materials and Methods:The MR images of 38 cases of fetal cardiovascular system with no abnormality revealed by prenatal ultrasound were retrospectively analyzed,and all of them were scanned by BSSFP sequence with single-phase and threephase.Three MRI doctors analyzed the anatomical structure of the four-chamber view and the transverse aortic arch view and scored them in the two groups of images.Results:Statistical differences were found between the single-phase scanning and three-phase scanning scores of the transverse aortic arch view(P=0.048).As for the four-chamber view for 38 selected patients,there was no significant difference(P=0.620).Conclusion:The BSSFP sequence with three-phase is helpful to improve the image quality of fetal cardiovascular,especially at the transverse aortic arch view,which can better display the anatomical structure of fetal extracardiac vessels and provide a new imaging idea for the display of fetal cardiovascular structure.
