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

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.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.The three-dimensional reconstruction images can clearly demonstrate the extent of the tumor size, location, and its relation to blood vessels and the skull.The three-dimensional reconstruction of enhanced CT image is conducive to operation plan designed to avoid damaging important anatomical structures.PubMed01148-504
