In vivo proton magnetic resonance spectroscopy of human fetal brain was performed in the third trimester of pregnancy. Spectra were obtained showing signals assigned to cerebral compounds such as N-acetylaspartate, creatine, and cholines. Relative signal intensities were similar to those observed in neonatal brain spectra recorded during the early postnatal stage.
在妊娠晚期对人类胎儿大脑进行了体内质子磁共振波谱分析。获得的波谱显示出归因于脑化合物（如N-乙酰天门冬氨酸、肌酸和胆碱）的信号。相对信号强度与出生后早期记录的新生儿脑波谱中观察到的相似。
