[Abstract] Objective: To investigate the value of susceptibility weighted imaging (SWI) for diagnosing acute massive cerebral infarction complicated by hemorrhage (ACIH) by 3.0 T MRI.Materials and Methods: 67 cases of ACIH underwent MRI scanning, the difference of detection rate of hemorrhagic lesions in ACIH was compared between routine sequences (T1WI, T2WI, FLAIR, DWI) and SWI sequence.Results: Of 67 cases ACIH, the conventional sequence detected bleeding lesions in 59 cases, the detection rate of 88.06%. SWI sequence detected 67 cases with the rate of 100%. The detection rate of ACIH with SWI sequence was higher than conventional sequences, the difference was significant. Occult hemorrhage showed the same signal with cerebral infarction without being detected in routine sequences, and clear low signal in SWI sequence. All the area [average (4.32±0.67) cm2] of cerebral hemorrhage in cerebral infarction with SWI sequence were greater than conventional MR sequences [average (2.87±0.48) cm2], the difference was statistically significant.Conclusions: SWI sequence can early detect more hemorrhage lesions than conventional sequences in ACIH, this sequence should be used as supplemental method of massive cerebral infarction.
