Application of susceptibility weighted imaging in diagnosis of cerebral microbleeds

Yao-Qi Han

Abstract

Objective:To investigate the features and the values of susceptibility weighted imaging in the diagnosis of cerebral microbleeds.Methods:97 patients with CMBs underwent MRI examination(including SWI sequences),to analyze four data(magnetic data/ phase data /SWI data /mIP data) and MPR of SWI sequences.Results:CMBs showed rounded or ovaled foci of ≤10 mm in size that appeared hypointensity or mixed-single intensity in SWI data.The presence of CMBs in Magnetic imaging and mIP imaging was similar to SWI data.Phase imaging showed hyperintensity single or mixed-single intensity.Coronal and sagittal of MPR images show CMBs as strip or spindle or teardrop-shaped hypointensity single.Conclusion:To analyze four group SWI data and MPR features of CMBs could improve the diagnostic level of CMBs and provide more imaging information accurately and exhaustively in cerebral vascular damage.
