The diagnostic value of susceptibility weighted imaging in patients with cerebral spontaneous microhemorrhage

Objective To investigate the susceptibility weighted imaging(SWI) in the diagnosis of cerebral microbleeds stove.Methods 165 patients with clinically suspected cerebral infarction and trauma underwent MRI scan and SWI scan sequence.The MRI image data were anlysed.Results For 107 patients with cerebral microhemorrhages,SWI sequences were round,oval,speckled low signal,distributing in the cortex,cortex and basal ganglia.Among them,47 patients had lacunar cerebral infarction,11 had cerebral infarction,12 had cerebral contusion and laceration.SWI showed no microhemorrhage in 58 cases.Conclusion The SWI sequence can reveal brain microhemorrhage and is a valuable tool for diagnosis of microhemorrhage in patients suffering from hypertension,lacunar infarction,acute cerebral infarction patients and traumatic brain injury.
