title: [Clinical application of multiplanar reconstruction and volume rendering with 64-slice spiral CT in the complex midfacial fracture].
abstract: OBJECTIVE
  To evaluate the value of clinical application of multiplanar reconstruction (MPR) and volume rendering (VR) with 64-slice spiral CT in the complex midfacial fracture.
  
  
  METHODS
  Forty-six patients with the complex midfacial fracture were examined with 64-slice spiral CT, then MPR and VR were performed in work station.
  
  
  RESULTS
  Of 46 patients, there are 366 fractures. MPR imaging clearly showed all (the rate were 100%). VR imaging could show all zygomatic fracture and mandibular fracture (the rate were 100%), but the showed rate were 94.3% in maxillary fracture, 93.2%. in orbital fractures, 13.0% in ethmoid fractures, 55.6% in sphenoid bone fracture,the mean rate were 86.3%. VR imaging could show the fracture location, range, fragment displacement from different direction by rotating picture and demonstrate the course of fracture line and deformities caused by fracture.
  
  
  CONCLUSIONS
  MPR imaging combination with VR imaging has important clinical value in diagnosing the complex midfacial fracture. 64 slice CT may improve displaying tiny and deep fracture.
