摘要: 目的:通过半傅立叶采集单次激发快速自旋回波(HASTE)序列和真实稳态进动快速成像(True FISP)序列对常见的几种双胎妊娠合并症进行脑部 MR 征象分析,并比较2种快速成像序列在双胎 MRI 中的应用价值。方法27例双胎妊娠合并症的孕妇行 HASTE 和 True FISP 序列扫描,对2个序列的图像质量、图像伪影进行分析,比较其在双胎结构和病变的显示能力,并分析胎儿脑部的 MR 征象。结果27例中7例出现脑部结构异常。2种序列均可以显示胎儿的解剖和病变,HASTE 序列较 True FISP序列评分均值高,呼吸伪影比 True FISP 序列明显。结论在双胎妊娠合并症的胎儿中,可能出现不同程度的神经系统病变,结合HASTE 和 True FISP 序列对胎儿病变特别是颅脑病变的显示非常重要。 Objective To compare the applications of half-Fourier acquisition single-shot turbo spin-echo(HASTE)sequence and true fast imaging with steady state precession(True FISP)sequence for the delineation of structures and diseases in several twin pregnancy with comorbidities and to explore the clinical value of two series of fast imaging for MRI of fetus.Methods 27 twin preg-nancy women with comorbidities were imaged with HASTE and True FISP sequences.All images were statistically analyzed in re-spect of imaging qualities and artifacts.MR signs of fetal brain were analysized.Results There were abnormal changes in brains in 7 of 27 cases.Both sequences could demonstrate the structures and lesions of the fatus.Imaging quality scores of HASTE were higher than that of True FISP,but with more respiratory blurring.Conclusion There might be varying abnormalities in central nervous system in twin pregnancy with comorbidities.Combining the demonstration abilities of HASTE and True FISP is needed when de-tecting fetus lesions,especially the brain.
