Objective To explore diagnostic value of magnetic sensitive weighted imaging in hemorrhagic cerebral infarction. Methods Twenty five patients with ischemic cerebral apoplexy admitted in the Radiology Department of the Hospital were selected as research subjects,retrospective analysis was made according to their clinical data,the patients underwent conventional magnetic resonance imaging(MRI),weighted diffusion imaging and magnetic sensitive weighted imaging,and internal infarct hemorrhage lesions detected via different scanning sequences were compared according to results of image analysis. Results Forty seven hemorrhage lesions were found in 25 patients,SWI sequence had 46 hemorrhage lesions shown,T1WI sequences displayed 27 hemorrhage lesions,DWI sequence displayed 16 hemorrhage lesions,and T1W2 displayed 11 hemorrhage lesions. The positive rate of SWI sequence on hemorrhage lesions was much higher than that of T1WI,T1W2 or DWI(p＜0.05),and the differences were significant.Fourteen patients were found to suffer from micro hemorrhage conditions. Conclusion The image of magnetic sensitive weighted imaging used in clinical diagnosis of hemorrhagic cerebral infarction casts certain characteristics,the display of magnetic sensitive weighted imaging on focal hemorrhage conditions were better than conventional MRI and DWI sequence,changed in veins in infarcts and conditions of tiny hemorrhage lesions may be got by this technique, which can offer important reference basis for clinical treatment,delivering high value of clinical use.
