The article deals with the MRI-based in vivo examination of early somatic embryos. The volume of water in the embryos was measured using two different methods. The first technique applied was proton density (PD) measurement of the sample via MRI (realized at the ISI, ASCR Brno). The second approach consisted in the dehydration and subsequent weighing of the sample (realized at MENDELU, Brno).Both the methods were compared. The correlation coefficient of the volume of water measured by these techniques is 0.816. The aspects of major interest for the investigation of the related biological processes are the various image contrasts and the change of the relaxation times T1 and T2 on the boundary between the embryo and the substrate.
