Abstract


Objective: advanced multislice CT studies have shown that the fine structure of the nasal bone fine structure of optimal scanning parameters, CT processing parameters and post-treatment CT images of the nasal bone fine structure to explore the CT image post-processing technology in the display nasal bone with The clinical value of the diagnosis of nasal bone fractures. : Select trauma line sinus the paranasal sinuses scan cases 100 cases (age 18-73 years) and 20 cases of dry cranial specimens, Siemens 16-slice spiral CT scan, Wizard workbench scan the original image after processing. Observe the morphological characteristics of the fine structure of the nasal bone, distribution law, next relationship, post-processing image quality score. Statistical analysis was performed based on ratings from the the CT scan singular image post-processing parameters, and a variety of post-processing techniques. Cf the last 35 cases of nasal bone fracture cases, investigate the CT image processing technology fine structure in the observation of the nasal bone and the clinical value of the diagnosis of nasal bone fractures. Results: 1, using collimator 0.75mmm, tube voltage 140KV the tube current 100mAs, into bed speed 6.6rim/rot, matrix 512 × 512, FOV310mm within a certain range (0.6-1.4) to change the pitch of the post-processing image quality no significant difference collimator 0.75mm the tube voltage 140KV, tube current 100mAs, into bed speed 6.6mm/rot, matrix 512 × 512, to obtain the raw data FOV310mm scan, and then use the reconstruction thickness 0.75mm, 50% reconstruction interval and 70 reconstructed image of the convolution kernel for the nasal bone MPR, INSPACE the best image quality, faster reconstruction speed 3, preferred post-processing parameters, image quality 2D post-processing techniques MIP and MPR nasal bone fine structure There was no significant difference. Three-dimensional after processing technology INSPACE shows the The nasal bone fine structure of the image quality was significantly better than the ordinary VRT. Observe the nasal bones subtle structure and application to the diagnosis of nasal bone fractures, the use of CT post-processing image effects significantly better than conventional CT axial tomography image, with the use of two-dimensional, three-dimensional reconstruction of the image separately using a reconstructed image effect. Conclusion: multislice CT after treatment technology can correctly display the structural characteristics of the nasal bone fine structure, distribution law, neighbor relations. Provides a wealth of diagnostic information for the diagnosis of nasal bone fractures, and take full advantage of the CT image post-processing technology can improve the detection rate to avoid the emergence of diagnosis, misdiagnosis nasal bone fracture.
