Abstract:
Objective To explore the diagnostic value of post-processing technique of multi-slice spiral CT(MSCT) in fracture of processus condylaris.Methods 51 cases with fracture of processus condylaris were undergone MSCT scan,the images were reconstucted by multiplanar reconsruction(MPR),surface shaded display(SSD) and volume rendering(VR).Results There were only with fracture lines in 19 cases and fragment displacement of fracture in 32 cases.The axial CT images could show the fracture clearly and the tissue surrounding fracture.MPR in sagittal and coronary could easily display the shift direction of processus condylaris.VR could show three-dimensionalchanges of processus condylaris.SSD may dispay the track and position of fracture’s lines.There were 9 cases with sagittal fracture ofprocessus condylaris,the processus condylaris were divided into two part by a interval on axial images,while processus condylaris appeared asfork on coronary and oblique coronary MPR.Conclusion On the base of axial imaging,according to different trauma and purpose,thedifferent composition of reconsruction can evaluate the fracture of processus condylaris well.
