T1, T2, proton density, and diffusion tensor of a Carnegie Stage 23 chemically fixed human embryo were measured to optimize the pulse sequences used for construction of the 3D anatomical database of the human embryo collection (Kyoto Collection). The results clarified that the correlation of the T1 and T2 is high, T1 and T2 of the liver were short comparing with other organs, and the volume of the liquid protons was about 30 % of the embryo specimen.
