The basic idea was to use MRI to produce a sequence of 3D gray scale image slices of various animals, subsequentlyimaged with a clinical CT system. For this purpose, these animals were used: toad, lungfish, python snake and a horseshoe crab. Each animal was sacrificed according to standard procedures at our biological department prior to the experimental procedures. Imaging was done as part of a joint educational initiative between our Biology Institute and Faculty of Health Science, where zoological students are recruited to the hospital medical facilities as part of their educational courses. MRI was done using a Philips Achieva 1.5 T system and CT was performed using a Siemens Somatom system. Axial and sagittal slices were acquired using standard T1w and T2w MRI sequences, and visualization was made using the Mistar software (Apollo Imaging Technology, Melbourne, Australia). Images were visually inspected, both in 2D and 3D, and compared with photographs and anatomy atlases found at library and on the internet.
