[Application of MSCT and post-processing images to fractures of nasal bone in forensic identification].
OBJECTIVE
To evaluate the application of MSCT and post-processing images to fractures of nasal bone in forensic identification.


METHODS
134 cases were examined by thin slice scanning with MSCT and all of the data were sent to workstation for MPR and SSD. The result of MSCT was compared with that of X-ray.


RESULTS
There are 55 (41.04%) cases of linear fracture, 46 (34.33%) cases of comminuted fracture, 27 (20.15%) cases of depressed fracture and 6 (4.48%) cases of no fracture in this sample. With X-ray or CR, 48 (35.82%) cases were misdiagnosed or underdiagnosed. 133 (99.25%) cases were confirmed by MSCT. Significance difference was found between X-ray and MSCT (chi2= 45.0816, P<0.001).


CONCLUSIONS
MSCT and post-processing images might be the chief evidence for nasal fractures in forensic identification.
