| Abstract: | Objective To study the CT signs of DAI in acute phase of brain injury in order to provide a imaging evidence for the diagnosis of DAI.Materials and Methods The CT imagesdata and its correlated clinic feature of 14 cases with DAI were analyzedretrospectively.Results Thediffuse brainedema were found in 14 cases.11 cases had hemorrhagelesions(less than 2 cm in diameter)in brain parenchyma which were at corticomedullaryjunction,callosum,brain stem,basal gandlia,internal capsule.Subarachnoid hemorr hage 9 cases,4 cases were associated with,epidural hematoma/subdural hematoma,and skull fracture 2 cases.Conclusion CT manifestation and its correlated clinic feature of DAI can provide reliable evidence for the earlyaccurate diagnosis of DAI. |
