				        	Objective:To explore the relationship between abnormality on susceptibility-weighted imaging (SWI)and newly-developed depression after mild traumatic brain injury.Methods:Totally 200 brain injury patients with routine CT and MRI were examined.All patients underwent MRI including conventional MR sequences and SWI.The number and volume of microbleed lesions were semi-automatically outlined and manually counted.All patients were followed up with the Structured Clinical Interview for DSM-Ⅳ Axis I Disorders (SCID-Ⅳ)within 1 year after TBI.Results:The difference in microbleed lesions on SWI was compared between the depressive and non-depressive groups.The depressive group had a higher rate of abnormality on SWI than which in the non-depressive group (P<0.001 ).Among patients that had exhibited microbleed lesions,the number and volume of lesions were greater in the depressive group than the non-depressive group (allP<0.001). These differences in numbers and volume of lesions were found only at the frontal,parietal,and temporal lobes (all P<0.001).Among patients that had exhibited microbleed lesions,the number and volume of lesions in other areas were not significantly different between the depressive and non-depressive groups.Conclusions:SWI was useful to identify the microbleed lesions after mild TBI.The distribution range and location of microbleed lesions were correlated with depression after TBI.
