Mouse Embryo Computed Tomography

Identically scaled renderings representing 3D μCT scans of embryos (E10.5 head according to paper methods) subjected to different fixation and scanning procedures.

A - 4% formaldehyde and secondary Bouin's fixation.

B - 4% formaldehyde + 1% glutaraldehyde with Iothalamate meglumine used as a contrast agent.

C - 4% formaldehyde + 5% glutaraldehyde plus contrast agent.

All embryos are shown in right 3/4 inferolateral view.

"Typical μCT renderings are represented by the embryos depicted in Figure 2A-C. The combination of aldehyde fixation and Cysto Conray® yields images (Figure 2B-C) with a surface quality comparable to embryos fixed with Bouin's solution (Figure 2A). Bouin's-fixed embryos appear have a rougher surface texture compared to those fixed with either glutaraldehyde mixture (Figure 2B-C). The identically scaled images of Bouin's fixed embryos appeared generally smaller compared to those fixed with glutaraldehyde mixtures, but a comparison of μCT images only cannot indicate the relative roles of fixation-induced tissue shrinkage or swelling."
