“Here we present a method that generates high quality iodine contrasted CT images from embryonic soft tissue. This method has two primary advantages over previous methodologies. First, it allows extraction of high quality nucleic acids following the CT scan, generating a 1:1 correspondence between scan and gene expression or DNA profile. Second, it minimizes the shrinkage artifacts associated with fixation and contrasting. The ability to relate a single sample to its genetic profile will allow study of both partially penetrant models and also increase our understanding of how genotype and phenotype are directly related.”

“A three-dimensional model of the wing musculature of the sparrowhawk (Accipiter nisus) was built using μCT and a 3% iodine-buffered formalin solution to test the ability of the technique for visualising wing musculature and obtaining quantitative data of muscle geometry.  This model allows the identification of the individual muscles comprising the avian wing and can be useful for further biomechanical analysis of flight.”
