Appllication of three-dimensional reconstruction of the enhanced CT in infratemporal fossa and parapharygeal space tumors

Objective:To reconstruct three-dimensional CT image of the skull,the blood vessels and the infratemporal fossa and parapharyngeal space tumors using Mimics software,and to discuss the clinical significance of the three-dimensional CT in diagnosis and preoperative surgical design.Methods: Four infratemporal fossa and parapharyngeal space tumors were studied using spiral CT Siemens 16 scanning technology,based on 2 mm thickness,and Mimics software was used to directly read the original image,and surface shaded technology was applied for reconstructing the spatial relationship of the vascular,skull and tumor structures.Results: The three-dimensional reconstruction images can clearly demonstrate the extent of the tumor size,location,and its relation to blood vessels and the skull.Conclusion: The three-dimensional reconstruction of enhanced CT image is conducive to operation plan designed to avoid damaging important anatomical structures.
