Application of Single-row CT Axial Helical Scanning Combined with Coronal Plane Recombinant Techniques on the Examination of Nasal

Objective: To explore the application of single row helical CT axial scan images combined with the multi-dimensional reconstruction of coronal images recombinant techniques on the diagnosis of nasal, and to evaluate its diagnostic value and feasibility. Methods: 219 cases who were treated in our hospital from January 2012 to March 2013 were selected to take part in the clinical trial. All the patients were conducted a single row of Otolaryngology spiral axial CT scans combined with the coronal scan plane, then the reconstructed image data with direct coronal the resolution of the scanned image were compared and analyzed so as to assess the quality and use of reconstruction value. Results: The images reconstructed by single-row spiral CT scan axial coronal could identify the boundary clearly and completely. The images that reconstructed by recombinant technology could identify the structure clearly and consistently as well as truly reflected the nasal cavity, para nasal sinuses and structural lesions of the actual situation. But the resolution is more direct coronal scan in patients with somewhat less. Conclusion: Although the resolution is not as good as direct coronal scan images by singlerow spiral CT scan axial coronal, the combination of the original image can still distinguish lesions which basically meets the diagnostic requirements and clinical needs.
