A website whose name says it all, the Multi-Dimensional Human Embryo site offers visitors an in-depth view of human embryos at 10 developmental stages (ranging from postovulatory days 28–56). The three-dimensional image datasets were acquired by magnetic resonance microscopy (MRM) over a number of years. (For you MRM aficionados out there, the collection includes images acquired by T1-, T2-, and Diffusion-weighted pulse sequences.) Visitors to the site first select a developmental stage, which subsequently allows them to browse photographs, animations, and MRI slices associated with that stage. The website contains a small list of links to related sites, and the technical information page provides the experimental details for specimen preparation and imaging. Overall, the website is easy to navigate and offers a fascinating glimpse into human development.
