Identically scaled renderings representing 3D μCT scans of embryos 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.
