Nuclear magnetic resonance proton imaging was used to obtain images of goat fetuses in utero. The long T1 relaxation time of amniotic fluid makes it appear black on proton density images when examined using the Aberdeen imager, and so allows very good discrimination of the position and structure of the fetus. Some fetal internal tissues can be seen on T1 images. These findings suggest that NMR imaging has great potential in pregnancy studies.
利用核磁共振质子成像技术获取山羊子宫内胎儿的图像。羊水的长T1弛豫时间使其在使用阿伯丁成像仪检查时，在质子密度图像上呈现黑色，从而能够很好地辨别胎儿的位置和结构。在T1图像上可以看到一些胎儿内部组织。这些发现表明，核磁共振成像在妊娠研究中具有巨大潜力。
