Application of 64 Multi-Detector Helical CT in Evaluation of Fracture of Accessory Nasal Cavity

Objective: To evaluate the diagnostic value of 64 multi-detector helical CT in fracture of accessory nasal cavity.Methods: 188 cases suspected fracture of accessory nasal cavity were performed with 64-MDCT.The data was transmitted to ADW4.2 workstation,and reconstructed by MPR,MIP,VR and generally analyzed with original axial images.Results: All the 69 fracture of accessory nasal cavity were demonstrated clearly by MDCT,and it can revealing the location,types,level and complication of fracture change.Conclusion: 64-MDCT is reliable and accurate in evaluating fracture of accessory nasal cavity,gradually become necessary modality examination in patients after trauma of facial surface.
