ABSTRACT
Objective To explore the method of three-dimensional reconstruction of fetal bilateral renal artery and its application value of three-dimensional visualization model.Methods One case of 31 weeks fresh fetal bilateral kidney specimens was infused with epoxy resin-titanium dioxide and then casted.Obtained the original two-dimensional CT image data sets through CT thin layer scanning of the casting mold.Reconstructed the three-dimensional model of fetal bilateral renal artery with the Mimics 17.0 software, and the model was compared with the casting mold specimen.Results The casting mold specimen of fetal bilateral renal artery clearly showed the shallow blood vessels, but it was difficult to observe the deep renal arteries.On the contrary,the three-dimensional model of fetal bilateral renal artery could help to observe and measure the deep renal arteries accurately,but it failed to show the shallow blood vessels clearly.Conclusion Based on the advantage of the three-dimensional model fetal bilateral renal artery and casting mold specimens,the direction and distribution of fetal bilateral renal arteries could be displayed with stereoscopic multi-level through the combination of virtual and reality,which may provide a reliable morphological data for anatomy teaching and fetal basic medical research information.
