概括。对 36 名妊娠 10 至 38 周的患者进行了磁共振成像 (MRI)，以确定不同妊娠时可识别的胎儿解剖结构。胎儿运动显着降低了妊娠早期和中期的图像质量，但在妊娠末期胎儿的解剖结构得到了清晰的展示。 T2加权序列显示胎儿大脑和肺部具有高信号强度。较短的 TR 导致 T1 权重，从而提供更好的整体解剖结构分辨率。 MRI 揭示了评估肺成熟度和胎儿生长迟缓的潜力。
Summary. Magnetic resonance imaging (MRI) was performed in 36 patients at between 10 and 38 weeks gestation to determine the fetal anatomy that could be identified at different gestations. Fetal motion significantly degraded the image quality in the first and second trimesters, but in the final trimester fetal anatomy was clearly demonstrated. T2 weighted sequences showed the fetal brain and lungs to have a high signal intensity. Shorter TR leading to a T1 weighting gave better resolution of the overall anatomy. MRI has revealed the potential for assessment of lung maturity and the growth‐retarded fetus.
