Abstract：Objective To investigate the effectiveness of SWI (Susceptibility Weighted Imaging) in diagnosis of hemorrhagic cerebral infarction. Methods Altogether 40 cases of hemorrhagic cerebral infarction patients underwent routine MRI (Magnetic Resonance Imaging), DWI (Diffusion Weighted Imaging) and SWI scanning so as to compare the detection rate of hemorrhagic cerebral infarction and display of the number of hemorrhage lesions. Additionally, the influence of different SWI sequences on demonstration of cerebral infarction lesions and surrounding micro-hemorrhagic lesions as well as intravenous changes in cerebral infarction lesions were observed. Results The SWI sequence demonstrated its superiority over DWI sequences and conventional MRI sequences in the detection rate of hemorrhagic cerebral infarction and display of the number of hemorrhage lesions (respectively χ2=37.5, χ2=51.82, P﹤0.05). Among 40 cases, micro-hemorrhage was seen outside the cerebral infarction region in 14 patients; small intravenous branches decreased markedly in 26 cases; veins obviously increased in 13 cases. Conclusion SWI showed superiority over conventional MRI and DWI sequences in positive detection rate of of hemorrhagic cerebral infarction, which could be taken as the first-choice examination method for hemorrhagic infarction.
