Abstract:
Objective To compare the advantages between CT and MRI examination and to evaluate the applied value of diffusion weighted imaging(DWI) in acute cerebral trauma.Methods 54 cases with cerebral trauma were undergone CT and MRI simultaneously,the advantages and disadvantages of both examination were analysed using self-comparative method. Results In showing subarachnoid hemorrhage, ultra-acute cerebral bleeding and bone fracture,CT was better than MRI,but cerebral contusion in 5 cases,laceration of white matter in 5 cases,acute white matter swelling in 2 cases and subdural haematoma in one case were misdiagnosed by CT.DWI was much better to show laceration of white matter and acute cerebral matter swelling than CT and conventional MRI.Conclusion In diagnosing acute cerebral bleeding and bone fracture, CT is better than MRI, for other diagnoses MRI better than CT. DWI should be applied to be a common scan method in diagnose of acute cerebral trauma.
