[Abstract] Objective: To evaluate the detection ability of MR susceptibility weighted imaging (SWI) in the cerebral micro-bleedings (CMB) and recessive cerebral micro-bleedings (rCMB).Materials and Methods: Magnetic resonance images of 45 cases with cerebral micro-bleeding were retrospectively analyzed. The features including size and location of the cerebral micro-bleedings were observed, and the detection rate of MRI and SWI were compared. These sequences of magnetic resonance imaging (T1WI, T2WI, FLAIR, DWI) and SWI were carried out. SWI was the VEN-BOLD-HR gradient echo sequence.Results: Altogether, 197 CMBs were deceted with a total of 162 CMB lesions on MRI, 191 CMB lesions on SWI. The detection rate of SWI is 1.18 times of the routine sequences. There was statistic difference in showing cerebral micro-bleeding among those sequences(χ2=22.90, P<0.01).Conclusion: SWI has a higher value in the detection of CMB and rCMB than the routine sequences, and should be one of the conventional sequences.
