Abstract:
Objective To investigate the diagnostic value of MSCT with multi-planar reconstruction(MPR)and maximum intensity projection(MIP)in diagnosis of spinal burst fracture.Methods 45 patients(53 vertebras)with vertebral burst fracture were examined by MSCT and processed with MPR and MIP.The imaging features were analyzed comparatively.Results The axial images clearly demonstrated the vertebral body vertically or transversely burst crack in 49 vertebras(92.5%),bony fragment inserted into the spinal canal and stenosis of spinal canal in 34 vertebras(64.2%).The sagittal images showed kyphosis in 28 vertebras(62.2%).The sagittal and coronal images showed decreased height of the vertebral body in 37 vertebras(69.8%)and depressed fracture of vertebral end plate in 19 vertebras(35.8%).Total 44 fractures were located at spinal appendix,39 were showed by axial images,35 by sagittal images and 33 by coronal images.MIP displayed the space changes of bone structures in all cases and rotary dislocation fracture in 6 cases(11.3%).Conclusion MPR and MIP are of significant values in diagnosis and clinical treatment of spinal burst fracture.
