The application value of 3.0T MR susceptibility-weighted imaging in cerebral microhemorrhage with traumatic brain injury

Cui Ming-hui

Abstract

Objective: To study the diagnostic value of susceptibility weighted imaging(SWI) in the cerebral microhemorrhage with traumatic brain injury.Methods: Twenty cases with cerebral microhemorrhage underwent T2* and SWI sequence.Results: In twenty cases,SWI and T2* of the microhemorrhage lesions were 18 cases and 7 cases and the detection rate were 90% and 35% respectively.The difference was statistically significant by statistical analysis of the score results(P0.005,χ2 test).All lesions were showed on basically bleeding SWI sequences clearly,microbleeds the number was 12.55 ± 7.35(P 0.001,paired t test).Conclusion: SWI was superior to the conventional T2* for cerebral microhemorrhage with traumatic brain injury.
