Eleven high risk fetuses between 32 and 37 menstrual weeks gestational age were examined by magnetic resonance (MR) imaging. Serial obstetrical sonograms, birth weights, and serial postnatal examinations were obtained in all subjects. Sagittal MR spin echo images obtained using TR = 0.5 sec and TE = 28 msec were useful for assessing subcutaneous fat. Prospective estimates of fetal fat stores correlated with neonatal outcome better than sonographic measurements of fetal growth parameters or actual birth weight. MR appears to be a safe and useful technique that offers information complementary to obstetrical sonography when IUGR is suspected.
对11例孕龄在月经周期32至37周之间的高危胎儿进行了磁共振（MR）成像检查。所有受试者均获得了系列产科超声检查、出生体重和系列产后检查结果。使用TR = 0.5秒和TE = 28毫秒获得的矢状面MR自旋回波图像有助于评估皮下脂肪。胎儿脂肪储备的前瞻性估计与新生儿结局的相关性优于胎儿生长参数的超声测量或实际出生体重。当怀疑胎儿宫内生长受限（IUGR）时，MR似乎是一种安全且有用的技术，可提供与产科超声检查互补的信息。
