Clinic value of susceptibility weighted imaging in the detection of cerebral microbleeds

Objective: To evaluate the clinic value of cerebrovasccular in susceptibility weighted imaging (SWI) in the detection of cerebral microbleeds (CMBs). Materials and Methods: The study sample consisted of 172 patients. SWI was used to detect the CMBs number, location and investigate their association with clinic parameter, lacunar infarction and white mattet change. Results: Significant correlations between microbleeds and age, hypertension, blood pressure, lacunar infarction, white matter change were observed. Systolic pressure was found closely associated with CMBs in patients with and without hypertension. In addition, a significant correlation between the severity of CMBs and that of lacunar infarction, as well as white matter changes was noted. Conclusion: SWI is a valuable tool in detecting microbleeds for the prevention and treatment of cerebrovasccular diseases.
